Accordingly, the projection 35 of the operation knob 12 is pressed against the cam surface 63 of the second sliding member 14, and the second sliding member 14 is pulled into the main body housing 11 against the urging force of the spring 16. This operation is also performed in synchronization with the first sliding member 13 via the rotor 15, and the first sliding member 13 is also drawn into the main body housing 11. As a result, the left and right rods 18 connected to both sliding members are pulled into the glove box 72, and the locking claws 74 are extracted from the locking holes 76 of the recess 71 as shown in FIG. The engagement is released and the glove box 72 can be opened.

  In this embodiment, since the key cylinder 17 is disposed on the side of the operation knob 12, a space for inserting a hand on the back side of the operation knob 12 can be made relatively wide. Further, when the operation knob 12 is rotated, the upper edge portion thereof comes close to the top wall 21 of the main body housing 11, but as shown in FIG. 2, a stepped portion 21 a is provided on the front side of the top wall 21. It is possible to prevent the upper edge portion from interfering with the main body housing 11.

  In the present invention, since the rotor 15 is attached to the bottom wall 22 of the main body housing 11, as described above, the width of the top wall 21 can be reduced and the stepped portion 21a can be provided. The width of the housing 11 in the front-rear direction can be reduced, and the entire apparatus can be made compact. As a result, in the present invention, the thickness of the front panel of the glove box 72 shown in FIG. 11 can be made relatively thin, and the opening 78 can be widened to make it easy to put in and out the contents.

  Next, an operation of locking the glove box 72 in the closed state using the key cylinder 17 will be described. When the glove box 72 is closed, a key (not shown) is inserted into the key hole 47 of the key cylinder 17 and the key is rotated to rotate the rotating portion 49 and bring the protrusion 48 to the position shown in FIG. Move. Accordingly, as described above, the movement of the second sliding member 14 into the main body housing 11 is restricted, and the movement of the first sliding member 13 into the main body housing 11 via the rotor 15 is also restricted. As a result, even if the operation knob 12 is pulled up, both sliding members do not move, so the rod 18 does not move and the locking claw 74 cannot be pulled out from the locking hole 76. Thus, the glove box 72 can be locked in the closed state.

  Further, when the lock by the key cylinder 17 is released, the key is inserted into the key hole 47, the rotating portion 49 is rotated in the opposite direction to the above, and the protrusion 48 is moved to the position shown in FIG. . As a result, the second sliding member 14 can be pulled into the main body housing 11, and thus the glove box 72 can be opened as described above by pulling up the operation knob 12.
