Slide it in the direction opposite to arrow a of 11. As a result, the boss 21 and the guide groove 22 formed on the end cover 4
The locking projection 23 is separated from the pivot 8 and the guide rail 19 formed on the mounting board 5, and the end cover 4 is removed from the mounting board 5. When the end cover 4 is removed as described above, by pulling the rotating plate 9 provided at the end of the shield plate 3 to the outside, the elastic projection 8 3 of the pivot 8 is elastically deformed inward and rotated. The plate 9 is allowed to pass through the shaft hole 11, whereby the shield plate 3 is removed from the cap body 1.

ので、その構造の簡略化を図ることが可能となる。As described above, according to the present invention, the mounting substrate fixed to the cap body is provided with the pivot, the locking portion and the lock member,
The shield plate is attached by fitting the shaft hole of the shield plate to the pivot of the mounting board, and the end cover is attached to the boss, the locked portion and the lock hole of the mounting board as the pivot, the locking portion and the lock member. Since they are engaged and attached to each other, the shield plate and the end cover can be easily attached to and detached from the attachment substrate without using screws such as screws, which allows the shield plate to be replaced in a short time. It becomes possible to do. Further, when the shield plate is attached to the pivot of the mounting substrate, the shaft hole of the shield plate is temporarily fixed by the elastic protrusion, so it is necessary to hold the shield plate by hand when attaching the end cover subsequent to the shield plate. Is eliminated and workability is improved. Furthermore,
Since the means for temporarily fixing the shield plate and the means for preventing the end cover from coming off to the outside are provided on the pivot of the mounting substrate, the structure thereof can be simplified.
