Further, a stopper 75a obtained by bending a part of the plate 75 is formed so as not to rotate excessively when the pressing lever 76 rotates in the closing direction.

  The operation of the lock mechanism 60 as described above will be described. When the cover 20 is closed to the housing part 30, the hook part 22 formed at the tip of the cover 20 pushes the upper part of the claw 62b of the rotary hook part 62, and the claw 62b is hooked on the hole 22a of the hook part 22 before long. . At this time, the rotating hook portion 62 tries to rotate in the opening direction by the bias of the spring 65a, but the opening / closing lever 63 is biased in the closing direction by the spring 65b, so that the stopper 62a of the rotating hook portion 62 is moved to the opening / closing lever 63. The cover lock portion 61 is locked in the closed state by receiving the cutout portion 63a.

  When the cover lock portion 61 is locked, the pressing portion 63c formed at the end portion of the opening / closing lever 63 stops in a state where the pressing lever 76 of the electromagnetic locking portion 71 is pressed and the tip of the plunger 73 is pulled out. At the same time, the spring 65b is biased in a direction to maintain this state.

  In order to release the lock of the cover lock portion 61, the solenoid 72 is operated by an electric signal so as to return the pulled out plunger 73. Then, when the plunger 73 returns, the pressing lever 76 rotates and presses the pressing portion 63 c of the opening / closing lever 63. As a result, the open / close lever 63 that has received the stopper 62a of the rotary hook 62 is released, and the rotary hook 62 rotates in the opening direction by the bias of the spring 65a. Then, the claw 62b hanging on the hole 22a of the hook portion 22 of the cover 20 is released and the cover 20 is unlocked.

  When the cover 20 is unlocked, the rotary hook 62 rotates in the opening direction by the bias of the spring 65a, and the convex portion 62d hits the stopper 64 and stops. At this time, the notch 63a of the opening / closing lever 63 stops in a state where the stopper 62a of the rotary hook 62 has escaped, and is in a standby state until the cover 20 is closed again.

  The lock mechanism 60 is not limited to the present embodiment as long as it uses a solenoid 72 that is an electromagnetic switch. For example, the cover lock unit 61 may be configured to release the lock by directly transmitting the operation of the plunger 73 of the solenoid 72 to the rotary hook unit 62. Further, as a means used for urging the cover 20, the rotary hook 62, and the opening / closing lever 63, a cylinder or the like sealed with air or oil may be used.
