BEST MODE FOR CARRYING OUT THE INVENTION
As shown in FIGS. 1 to 3, the vehicle door outside handle device 1 mainly includes a bezel 2 and a handle grip 3. The bezel 2 is an elongated member having a recess 21 formed in the center, and is bolted to a door outer panel 4 of a vehicle door with a seal member 5 interposed therebetween. The handle grip 3 is a rod-shaped member extending in the longitudinal direction of the bezel 2, and one end thereof is rotatably supported by the bezel 2.
[0011]
Arm portions 31 and 32 are formed on one end side and the other end side in the longitudinal direction of the handle grip 3, a U-shaped groove 33 is formed on the arm portion 31, and a hole portion is formed on the arm portion 32. 34 are formed.
[0012]
The opening 22 through which the arm portion 31 of the handle grip 3 is inserted and the opening 23 through which the arm portion 32 is inserted are formed in the bezel 2. The hole 34 of the arm portion 32 of the handle grip 3 inserted into the opening 23 receives the bell crank link 6 rotatably supported on the back surface of the bezel 3. The bell crank link 6 is connected to an open lever (not shown) of the vehicle door lock device via a rod, a cable, or the like.
[0013]
A shaft portion 24 is formed integrally with the bezel 2. The shaft portion 24 is located in the opening portion 22, extends in the up-down direction (and the up-down direction) of the shielding door, crosses the opening portion 22, and has a U-shape of the arm portion 31 of the handle grip 3. It is fitted in the groove 33. As a result, the handle grip 33 is supported by the bezel 2 so as to be rotatable about the shaft portion 24 in a direction substantially perpendicular to the door outer panel 5 (and in the direction indicated by A).
[0014]
As shown in FIG. 3, the U-shaped groove 33 formed in the arm portion 31 of the bezel 3 is constituted by a pair of bearing surfaces 33a and 33b arranged to face each other. The bearing surfaces 33a and 33b are capable of slidingly contacting the outer peripheral surface 24a of the shaft portion 24 in the vertical direction of the vehicle door, respectively, and sandwich the shaft portion 24 between the bearing surfaces 33a and 33b. Each of the bearing surfaces 33a and 33b has a convex shape having a pair of inclined surfaces 33c and 33d such that a substantially central portion in the vertical direction of the vehicle door projects and both end portions in the vertical direction are lower than the central portion. In the portion, the outer peripheral surface 24a of the shaft portion 24 is in line contact with the outer peripheral surface 24a. In both end portions, a predetermined gap B is formed between the portion and the outer peripheral surface 24a of the shaft portion 24. Thus, the handle grip 3 is moved up and down in the vehicle door until the inclined surfaces 33c and 33d of the bearing surfaces 33a and 33b come into surface contact with the outer peripheral surface 24a of the shaft portion 24 about the center of the bezel 2 as shown in FIG. (In the direction C shown in FIG. 3) by the clearance B. The shaft portion 24 of the bezel 2 has a pair of wall portions 24b which hold the support surface 33b side of the arm portion 31 of the handle grip 3 with a gap enough to allow the handle grip 3 to rotate in the vertical direction of the vehicle door. It is formed to extend. The wall portion 24b suppresses vertical play of the handle grip 3 with respect to the bezel 2.
[0015]
In the above-described configuration, when the handle grip 3 is raised and operated, the handle grip 3 is moved around the shaft portion 24 disposed at one end thereof and the outer peripheral surface 24a of the shaft portion 24 and the bearing surfaces 33a, 33b of the U-shaped groove portion 33. 2 and 3 in the direction indicated by A in FIG. Accordingly, the hole 34 on the other end rotates the bell crank link 6 to operate the open lever of the door lock device, and as a result, the vehicle door is opened.
[0016]
When the handle grip 3 is raised and operated, the rotation direction of the handle grip 3 (direction substantially orthogonal to the door outer panel 5) in the operation direction of the vehicle outside handle device 1 itself, depending on the mounting position on the door outer panel 5. (The wall 24b of the shaft 24 is bent without suppressing the inclination). At this time, the handle grip 3 is moved by the gap B between the outer peripheral surface 24a of the shaft portion 24 and the bearing surfaces 33a, 33b of the U-shaped groove 33 in accordance with the inclination of the handle grip 3 in the operation direction shown in FIG. It rotates in the direction. Thereby, the twist between the shaft portion 24 and the U-shaped groove portion 33 is eliminated, and the sliding friction between the outer peripheral surface 24 of the shaft portion 24 and the bearing surfaces 33a, 33b of the U-shaped groove portion 33 is reduced, so that the handle grip 3 Smooth operation (operation with light operation force) is ensured. The play in the rotational direction of the handle grip 3 is suppressed by the line contact between the outer peripheral surface 24a of the shaft portion 24 and the bearing surfaces 33a, 33b of the U-shaped groove portion 33 at the central portion in the vertical direction of the vehicle door.
[0017]
As described above, since the twist between the shaft portion 24 and the U-shaped groove portion 33 at the time of the raising operation of the handle grip 3 is eliminated, an excessive load due to the twist is not applied to the U-shaped groove portion 33, The strength of the U-shaped groove 33 can be ensured without increasing the weight, for example, by increasing the thickness of the U-shaped groove 33.
[0018]
In the present embodiment, the shaft portion 24 is formed in the bezel 2 and the U-shaped groove portion 33 is formed in the handle grip 3. On the contrary, the U-shaped groove portion 33 is formed in the bezel 2 and the handle grip is formed. The shaft portion 24 may be formed in 3.
[0019]
【The invention's effect】
According to the present invention, the handle grip is supported rotatably in the vertical direction of the vehicle door around the substantially central portion of the shaft portion and the U-shaped groove in the vertical direction of the vehicle door. The turning operation can raise and operate the handle grip without prying the shaft portion and the U-shaped groove portion. Thus, the load applied to the U-shaped groove and the sliding friction between the outer peripheral surface of the shaft and the bearing surface of the U-shaped groove can be reduced.
