た位置に保持されるようになっている。A hook 42 serving as a locking member is integrally connected to the lock shaft 22 at the end on the opening side of the recess 16. The hook 42 has a substantially F shape, and the long side portion is along the side wall of the recess 16 and the end of the long side portion is a thin portion 44 as a connecting member so that the tip of the short side portion faces the opening center side of the recess 16. Is connected to the lock shaft 22 with
The thin portion 44 is deformed so that it can swing with respect to the lock shaft 22. In this hook 42, a rib 46 is formed from the short side portion protruding from the middle portion of the long side to the vicinity of the thin portion 44, and a spring locking protrusion 48 is formed at the end portion of the rib 46 on the thin portion 44 side. ing. One end of a compression coil spring 50, which constitutes another part of the swing of the locking member having the intermediate portion housed inside the lock shaft 22, is fitted to the spring locking projection 48. The other end of the compression coil spring 50 is fitted into the case 20 and urges the hook 42 together with the lock shaft 22 toward the opening side of the recess 16. In response to this urging force, when the open / close door 12 is in the non-fully closed state shown in FIG. 1, the lock shaft 22 moves toward the opening side of the recess 16 where the claw 36 abuts the peripheral wall of the recess 16 of the engaging hole 39. Located at the limit of movement,
42 is held at a position inclined along the slope 28 of the case 20 toward the side wall of the recess 16.

うにされている。The hook 42 has a short side portion protruding from the middle portion of the long side as a door contact portion 52, and when the opening / closing door 12 is fully closed, the hook portion 18 of the opening / closing door 12 is brought into contact with the door contact portion 52 and the hook portion 18 It is adapted to be pressed by and to receive a moving force inward of the recess 16. Upon receiving this moving force, the hook 42 is moved inward of the recess 16 together with the lock shaft 22 when the opening / closing door 12 is fully closed. Hook 42
16 is guided by the inner wall of the case 20 when it is moved inward, and is swung in the direction of arrow B in FIG.
In the fully closed position, the sloped surface of the case 20 as shown in FIG.
It is arranged to be substantially parallel to the side wall of the recess 16 apart from 28. The lock shaft 22 projects during the movement of the recess 16 inward.
The projection 34 is pushed out from the inside of the case 20 by hitting the projection 34, and the projection 34 is made to correspond to the engaging groove 38 at the fully closed position of the opening / closing door 12.

阻止される。As a result, the hook 42 is guided by the inner wall of the case 20 and is moved in the direction of the arrow B in FIG. Then, the locking part 54 is inserted into the concave part 17 of the opening / closing door 12 and is locked to the hook part 18 so as to be substantially parallel to the side wall of the recess 16 away from the inclined surface 28 of the case 20. On the other hand, the lock shaft 22 is moved to the inner side of the recess 16 while the block 40 is held by the frictional force with the inner wall of the case 20 to hold the engagement groove 38 at the end of the recess 16 on the opening side. The lock shaft 22 is moved to the inner side of the recess 16 so that the projection 34
Is pushed out from the inner wall of the case 20, and the projection 34 corresponds to the engagement groove 38 at the fully closed position of the opening / closing door 12. When the projection 34 corresponds to the engagement groove 38, the flexible portion 32 is restored in shape and the projection 34 enters the engagement groove 38, and the movement of the lock shaft 22 toward the opening of the recess 16 is prevented.
これによって開閉扉12が全閉位置でロツクされる。As a result, the opening / closing door 12 is locked at the fully closed position.

ブロツク40に乗り上げられる。In order to open the opening / closing door 12 from this state, the opening / closing door 12 may be pushed inward of the recess 16. When the open / close door 12 is pressed, the hook 42 is pressed and the hook 42 is further pushed into the recess 16 together with the lock shaft 22 against the biasing force of the compression coil spring 50. When the lock shaft 22 is pushed in, it is pressed by the block 40 and the projection 34 is pulled out from the inside of the engaging groove 38,
You can ride on Block 40.

される。Here, when the opening / closing door 12 is no longer pressed, the compression coil spring 50 urges the hook 42 so that the hook 42 is recessed together with the lock shaft 22.
Moved to the opening side of 16. When the lock shaft 22 is moved to the opening side of the concave portion 16, the block 40 is moved relatively to the lock shaft 22 by the frictional force with the projection 34 so that the projection 34 does not enter the engagement groove 38. The lock shaft 22 is moved until the pawl 36 comes into contact with the inner peripheral wall of the engaging hole 39 of the case 20 on the opening side of the recess 16. On the other hand, the hook 42 is on the slope during the movement of the lock shaft 22.
The direction in which the locking portion 54 is guided by the 28 and disengages from the hook portion 18 (first
When the rock shaft 22 is swung in the direction opposite to the arrow B direction in the figure and the movement of the lock shaft 22 is stopped, as shown in FIG.
The locking portion 54 is inclined along 28 and is pulled out from the recessed portion 17 of the opening / closing door 12 and disengaged from the hook portion 18, whereby the locking state of the opening / closing door 12 is released and the opening / closing door 12 can be opened. It is said that

開放する。That is, the closing operation of the opening / closing door 12 pushes the door contact portion 52 against the opening / closing door 12, so that the hook 42 pivots and the locking portion 54 is inserted and engaged in the recess 17 of the opening / closing door 12, and at the second position. The pushing force to the lock shaft 22 is transmitted. At the second position of the lock shaft 22, the lock shaft 22 is unlocked by pushing the open / close door 12 and the hook 42 is swung in the opposite direction when the lock shaft 22 is moved to the first position, and the locking portion 54 is disengaged from the recess 17. Then, the opening / closing door 12 is opened.
このように本実施例では、開閉扉12に磁性体を設定する
ことなく、開閉扉12をロツクでき、しかも従来のくわえ
