The operation of the lock mechanism 130 will be described.
First, as shown in FIG. 4, a state in which the movable members (the handle 620, the rod 550, the rotation plate 540, the first holding member 520 and the second holding member 530) are in the lock position will be described. The grip portion 621 of the handle 620 is located at the first position P1 which is not pulled in the opposite direction to the Y direction. Further, since the leg portion 622 also extends in the Y direction, in the holding device 500 connected to the rod 550, the first holding member 520 and the second holding member 530 are positioned in the vertical direction (Z direction), The concave notch 521 of the first holding member 520 and the concave notch 531 of the second holding member 530 form an elliptical through hole 522. Therefore, at the lock position of the movable member, the lock pin 305 of the case 300 is inserted into the through hole 522. That is, the lid 400 is locked to the case 300 in the closed state via the first gripping member 520 and the second gripping member 530 and the lock pin 305. As described above, when the movable member is at the lock position, the position of the grip portion 621 (operation portion) is at the first position P1. The handle 620, the rod 550, the pivot plate 540, the first gripping member 520, and the second gripping member 530 are examples of movable members.

  Next, as shown in FIG. 7, a state where the movable member is in the unlocking position will be described.

  In the unlocked position, the grip portion 621 of the handle 620 is located at the second position P2 pulled in the opposite direction to the Y direction. The second position P2 of the grip portion 621 protrudes in the opposite direction of the Y direction which is the operation direction of the grip portion 621 more than the first position P1 described above. In addition, when the gripping portion 621 is pulled, the leg portion 622 pivots downward, the rod 550 moves downward, and the pivoting plate 540 and the first gripping member 520 center on the second support pin 514 as a counterclockwise. It turns around. Thus, the second gripping member 530 also pivots clockwise about the third support pin 515. Here, the first rear protrusion 520 b and the second rear protrusion 530 b are pushed by the lock pin 305 of the case 300 and move in the direction opposite to the Y direction. That is, the lid 400 is opened by the distance D by the operation of pulling the handle 620. Further, as shown in FIGS. 8 and 9, when the grip portion 621 of the handle 620 is pulled and the leg portion 622 pivots downward, the leg portion 622 with respect to the tip surface of the large diameter portion 633 of the movement limiting pin 630 When the pressure is released, the biasing force of the coil spring 640 causes the movement restricting pin 630 to protrude in the direction opposite to the X direction and engage with the notch 624 of the leg 622. Therefore, in the unlocked position, the movement restricting pin 630 holds the leg portion 622 downward and the lid 400 in the open state.

  Here, when the movable member is in the lock position, the movement restricting pin 630 is pressed by the leg 622 as shown in FIG. When it is urged (see FIG. 5), the tip end is located at the allowable position P3 pressed against the side surface 625 of the leg 622. When the movement restricting pin 630 is in the allowable position P3, as shown in FIG. 4, the movable member is allowed to move from the locked position to the unlocked position.

  On the other hand, when the movable member is in the unlocked position, as shown in FIG. 8, the movement restricting pin 630 engages with the handle 620 and the unlocked position of the first gripping member 520 and the second gripping member 530 Movement from the to the lock position is restricted. Further, in the unlocked position, as shown in FIG. 9, the movement restricting pin 630 is located at the restricting position P 4 engaged with the leg portion 622 of the handle 620. When the movement restricting pin 630 is in the restricting position P4, as shown in FIG. 7, the movement of the first gripping member 520 and the second gripping member 530 from the unlocked position to the locked position is restricted. Also, the lid 400 is held in the open state.

Next, the operation of the lock release mechanism 700 will be described.
First, as shown in FIG. 10, in the locked position, the large diameter portion 633 of the movement restricting pin 630 is engaged with the notch portion 624 of the leg portion 622, and the leg portion 622 is turned downward. . Then, when a dedicated key is inserted into the key hole 713 (see FIG. 3) of the cylinder lock 710 and the rotation plate 720 is rotated together with the inner cylinder 712, as shown in FIG. The movement limiting pin 630 moves in the X direction together with the bracket 631. Then, the movement restricting pin 630 is disengaged from the notch portion 624 and the engagement is released, and the grip portion 621 of the handle 620 can be turned. Therefore, when the grip portion 621 is pushed in the Y direction, as shown in FIG. 4, the leg portion 622 pivots upward and the rod 550 rises. Then, the first gripping member 520 and the second gripping member 530 are pivoted, and the lid 400 is locked to the case 300 in the closed state via the first gripping member 520, the second gripping member 530, and the lock pin 305. . Thus, the lock release mechanism 700 releases the restriction on the movement of the movable member from the lock release position to the lock position by the lock mechanism 130 in response to the operation of the key.
