に当接するように被嵌されたものである。(Example) The details of the present invention will be described in detail below with reference to a typical example shown in the drawings. 1 is a permanent magnet made of a metal ferromagnetic material or a compound ferromagnetic material, typical examples of which are ferrite and pyrotite. The permanent magnet 1 is designed to have a short planar rectangular or rectangular shape or any other arbitrary shape determined depending on the intended purpose of use, and the permanent magnet 1 is made of iron, It is placed on a ferromagnetic plate 2, typically made of nickel-cobalt or an alloy or compound thereof, or an alloy or compound of manganese-chromium, from one magnetic pole surface a, and is then adsorbed by any method described below. It is firmly attached. Reference numeral 3 denotes a bottomed dish-shaped case made of a non-magnetic material having a bottom surface 3a and a side surface 3b.An engagement hole 3d parallel to the side surface 3b is opened from one side surface 3b' in the bottom surface 3a. The matching hole is provided with a hole edge 3c that is shorter than the side surface 3b', and the permanent magnet 1 is inserted between the side surface 3b' and the hole edge 3c, and is attached to protrude from the edge of the side surfaces 3b and 3b'. The permanent magnet 1 is held in the case 3 by causing the secured locking piece 3e to bypass the circumferential surface of the ferromagnetic material 2 which is attracted and fixed to the permanent magnet 1. Case 3 is generally made of brass or synthetic resin from the viewpoint of aesthetic appearance and protection of permanent magnet 1 from damage, but it is not limited to this and is conceptually always used. Magnetic and diamagnetic materials are used. Of course, in order to maximize the force acting between the magnetic poles, the case 3 is made as thin as possible and is fitted onto the permanent magnet 1 so as to come into close contact with it.

である。(Effects) As described above, the present invention has a characteristic structure, in particular, the permanent magnet 1 is relatively small and simple, and the engaging plate portion 4c is attached to the edge of the permanent magnet 1 in the opening direction when in use.
The main magnetic closing circuit is configured via the engagement plate part 4c at the edge of the opening, and the inner part connected to the edge of the opening is made into a relatively wide magnetic pole end surface, The ferromagnetic plate 4 having the contact plate part 4c is magnetically attached in a detachable manner, and the plate part 5c of the mounting leg member 5 is made flush with the attracting surface of each of the ferromagnetic plates 2 and 4. This prevents the end face of the engaging plate portion 4c from separating from the suction surface, especially from tilting, due to external pressure applied to the opening edge, thereby ensuring reliable suction.

た。 In attaching the leg members 5 to the ferromagnetic plates 2 and 4, it is possible to omit welding, any other adhesive means, and the labor and cost of assembly, thereby avoiding assembly errors and losses due to them. At the same time, the leg member 5 does not come off unless the engagement tool is removed from the material to which it is attached, such as a bag or handbag, making it possible to securely attach the engagement tool and making it extremely easy to assemble the engagement tool.

立てるのでパーツが嵩張らず運搬、格納に便利で
ある。 Furthermore, since the leg member 5 can be attached by simply inserting it into the slits 2b and 4b, it can be assembled at the site where the engaging tool is attached, so the parts are not bulky and are convenient to transport and store.
又、各部品はすべてプレスの一工程で作成でき
るので製作コストが低廉であり、前記の組付コス
トの安さと相俟つて低廉な製品提供を可能とした
ものである。 In addition, since all the parts can be made in one press process, the manufacturing cost is low, which, together with the aforementioned low assembly cost, makes it possible to provide a product at a low cost.
