d, and the pinion gear 9
and the tip of the rear protrusion 7c is in a position where it can come into contact with the interlocking member 3b when the cylinder lock 3 is in the unlocked position, but not in contact with the interlocking member 3b when it is in the locked position. It is set. Further, a spring member 10 is compressed between the inner surface of the right side wall 7e of the slide member 7 and a spring receiving plate 8a protruding from the bottom plate 8, and biases the slide member 7 in the right direction.

Further, a locking member 12 is rotatably supported in a penetrating state on the bottom plate 8 near the case partition wall 2f, and a hook portion 12a is formed at the lower end of the downward protruding portion of the locking member 12. A spring 13 is wound around the upper protrusion inside 2 to bias it clockwise in the figure. On the other hand, a striker 14 is inserted from the box body at a position corresponding to the hook portion 12a.
is provided in a protruding manner so that it can be engaged with and disengaged from the hook portion 12a.

Next, the operation of the above device will be explained.

In the cylinder lock 3, the key hole 3a is in the unlocked position at the solid line position in FIG. 1, and the locked position at the chain line position. In the unlocked position, as shown in FIGS. 2 and 3, the interlocking member 3b of the cylinder lock 3 is located close to the locking member 12, the protrusion 3c is located in the middle of the groove 9a, and, The lock plates 6, 6 housed in the cylinder lock 3 protrude into the unlocking side key protruding grooves 5, 5. At this time,
The slide member 7 is biased by the spring member 10 so that the right side portion 7a protrudes to the right from the case top wall 2g. Further, the locking member 12 is biased by a spring 13 so that the hook portion 12a is attached to the striker 14.
The opening/closing lid 1 is held in the closed position.

When performing an opening operation at the unlocked position, first, the right side wall 7e of the slide member 7 is pushed inward in a direction orthogonal to the axial direction of the cylinder lock 3, as shown in FIGS. 5 and 6. With this operation, the tip of the rear protrusion 7c of the slide member 7 comes into contact with the interlocking member 3b of the cylinder lock 3, rotates the interlocking member 3b, and comes into contact with the upper side of the locking member 12, thereby locking the locking member 12.
Rotate counterclockwise to disengage from the striker 14. At this time, the cylinder lock 3 rotates until the lock plates 6...6 reach the side ends of the grooves 5. On the other hand, the rack gear 7d of the front protrusion 7b of the slide member 7 meshes with the pinion gear 9 to rotate the pinion gear 9 clockwise. At this time, the groove 9a moves along the protrusion 3c, and the protrusion 3c is positioned on the right side of the groove 9a. As described above, when the fingers are inserted into the gaps A and B with the striker 14 disengaged, the partition wall 2f and the right side wall 7e of the slide member are grasped and pulled forward, and the opening/closing lid 1 is opened.

Also, when the opening/closing lid 1 is closed and released, the locking member 12 is rotated by the spring 13 and the striker 14 is rotated by the spring 13.
At the same time, the cylinder lock 3 is rotated by the rotation of the lock member 12 via the interlocking member 3b, and the slide member 7 is moved to the right by the spring member 10 to the unlocked position shown in FIGS. 1 to 3. to return to.

On the other hand, when the key is inserted into the cylinder lock 3 and the cylinder lock 3 is rotated 90 degrees clockwise to the locked position, the interlocking member 3b is moved to the protrusion 7c of the slide member 7.
As shown by the arrows in FIGS. 3 and 4, the pinion gear 9 rotates without interference, and the protrusion 3c also rotates, so that the pinion gear 9 is rotated clockwise after coming into contact with the left end of the groove 9a of the pinion gear 9. Rotate in conjunction with the direction. Therefore, the rack gear 7d of the slide member 7 moves to the left, and the slide member 7 moves to the left. In the locked position, the entire right half 7a of the slide member 7 is held in the center of the case located below the case top wall 2g. At this time, the protrusion 7c of the slide member 7 is also moving to the left, or is in a position parallel to the lock member 12 and not in contact with each other, as shown in FIG. Therefore, even if the slide member 7 is operated,
The locking member 12 does not rotate and is securely locked.

Note that this invention is not limited to the above embodiment, and as shown in FIGS. 9 and 10, instead of the pinion gear 9, a cam 3'd is provided protruding from the outer periphery of the cylinder lock 3', and a slide At the tip of the protruding part 7'b of the member 7', there is an engaging part 7'f that protrudes to the left side of the cylinder lock 3'.
may be formed. In this embodiment, when the cylinder lock 3' is in the unlocked position, as shown in FIG.
The cam 3'd is located on the right side of the slide member engaging portion 7'f, and can therefore push the slide member 7' to the left to release the lock member 12 via the first protrusion 3'b. On the other hand, when the cylinder lock 3' is rotated to the lock position, the cam 3'd pushes the engaging portion 7'f and moves the slide member 7' to the left, so that the slide member 7' is at the center hidden under the case top wall 2g. and hold in the locked position.

As is clear from the above explanation, according to the glove box locking device of this invention, when the glove box is locked, the slide member moves to the center of the case and is hidden by the top wall of the case and becomes invisible, but when it is unlocked, it is located on the right side. This has the advantage that it can be seen sticking out from the top wall of the case, and that it can be determined at a glance whether or not it is locked.
