  The operation device for the glove box 1 according to the present invention includes the stopper mechanism STP, the knob 80, and the cam portion 18 provided in the box housing 10, and each rod rod 50 is moved from the unlocked state shown in FIG. To the locked state shown in Fig. 1, or from the locked state to the unlocked state. The manner in which the operating device for the glove box 1 operates each rod rod 50 will be described below with reference to FIGS. 9A to 11A are cross-sectional views as viewed downward from the height of the upper surface of each rod rod 50, and FIGS. 9B to 11B are respective engagement protrusions 60b of the stopper body 60. Sectional drawing which looked at the downward direction from the height of is shown.

The operating device for glove box 1 operates each rod rod 50 from the unlocked state to the locked state as follows.
In the unlocked state of each rod rod 50 (see FIG. 9), the front extension 64 of the stopper body 60 faces diagonally left frontward. As shown in FIG. 9B, each engagement protrusion 60 b of the stopper body 60 is at a position away from each engagement groove 72 a of the case 70.
When the box body 20 is pushed into the box housing body 10 (see FIG. 10), the contact 64a of the stopper body 60 moves along the cam portion 18 of the box housing body 10. As a result, the stopper body 60 rotates clockwise to the rotational position in FIG. 10 against the urging force in the rotational direction by the spring S, and each rod rod 50 slides outward of the box body 20. Each engagement protrusion 60b of the stopper body 60 moves to the center position of each engagement groove 72a shown in FIG. 10B, and linearly moves downward by the urging force of the spring S in the linear movement direction. It is dropped into the joint groove 72a.
When the box body 20 is released from the pushing operation, the stopper body 60 rotates counterclockwise from the rotation position of FIG. 10 to the rotation position of FIG. Each engagement protrusion 60b of the stopper body 60 rotates while being dropped into each engagement groove 72a of the case 70 by the urging force of the spring S in the linear movement direction, and engages with the side wall W of each engagement groove 72a. By doing so (see FIGS. 11 to 12), the rotation is stopped at the rotational position of FIG. With the rotation of the stopper body 60 from the rotational position in FIG. 10 to the rotational position in FIG. 11, the contact 64 a of the stopper body 60 moves rearward along the cam portion 18 of the box housing body 10. Then, the box body 20 is pushed back toward the rear side by the dimension that the contact 64a has moved to the rear side. In FIG. 11, the design plate 24 is positioned on the open surface of the box housing 10, and the box body 20 is in a state of being closed with respect to the box housing 10.
In synchronization with the engagement protrusions 60 b of the stopper body 60 engaging the side walls W of the engagement grooves 72 a of the case 70, the lock portions 50 b of the rod rods 50 are rear surfaces of the lock holes 14 of the box housing 10. (See FIG. 11). Due to the engagement between the lock portions 50b and the lock holes 14, the rod rods 50 can maintain the locked state. In addition, in the locked state of each rod rod 50, the position of each rod rod 50 is regulated by the engagement of each engagement protrusion 60b with each engagement groove 72a. The engagement allowance of each engagement protrusion 60b with respect to each engagement groove 72a is set to be smaller than the engagement allowance with respect to each lock hole 14 of each rod rod 50.

The glove box 1 operating device operates each rod rod 50 from the locked state (see FIG. 11) to the unlocked state (see FIG. 9) as follows.
In the locked state of each rod rod 50, when the knob 80 in the free state is pushed up, the left and right restriction release protrusions 80b of the knob 80 are dropped into the engaging grooves 72a of the case 70. The mating protrusions 60b are pushed upward from the respective engaging grooves 72a (see FIGS. 12 and 13). By the linear movement of the stopper body 60, the engagement of the engagement protrusions 60b with respect to the engagement grooves 72a is released. In FIG. 13, only the engagement release of the engagement protrusion 60b by the right-side restriction release protrusion 80b is shown.
When the engagement of each engagement protrusion 60b with respect to each engagement groove 72a is released, the stopper body 60 is counterclockwise from the rotation position of FIG. 11 to the rotation position of FIG. Rotate. Along with this, each rod rod 50 is pulled back inward, and the engagement of the lock portion 50b of each rod rod 50 with each lock hole 14 is released (see FIG. 9). The stopper body 60 stops rotating at the rotational position of FIG. 9 when each rod rod 50 is received by the rod receiving portion 32 of the box body 20 as shown in FIG.
As the stopper body 60 rotates counterclockwise from the rotational position in FIG. 11 to the rotational position in FIG. 9, the contact 64 a of the stopper body 60 moves rearward along the cam portion 18 of the box housing body 10. Then, the box body 20 is pushed back toward the rear side by the dimension that the contact 64a has moved to the rear side. Thereby, the design board 24 will be located back rather than the open surface of the box accommodating body 10 in the unlocking state (refer FIG. 9) of each rod rod 50. FIG. That is, when each rod rod 50 is operated in the unlocked state by the operation of the knob 80, the box body 20 automatically pops out from the box housing 10 and can be freely opened.

In the above-described embodiment, the engagement allowance between each engagement groove 72a and each engagement protrusion 60b in the stoper mechanism STP is set smaller than the engagement allowance for keeping each rod rod 50 in the locked state. Thus, in order to put each rod rod 50 in the unlocked state, the knob 80 is operated to disengage the engagement grooves 72a having small engagement allowances from the engagement protrusions 60b and the positions of the rod rods 50. What is necessary is just to cancel | release regulation and the operation stroke of the knob 80 at this time can be made small.
In the above-described embodiment, the stopper body 60 of the stoper mechanism STP operates each rod rod 50 in a locked state against the urging force of the spring S when the box body 20 is closed, and the spring body STP is attached. Each engaging protrusion 60b is configured to be engaged with each engaging groove 72a by force. Thereby, even though each rod rod 50 is constantly receiving the urging force in the unlocking direction, when the box body 20 is closed, the position of each rod rod 50 is restricted to the locked state by the stopper mechanism STP.
In the above-described embodiment, since the single spring S functions to give two different urging forces to the stopper body 60, the number of members is smaller than when each urging force is given by an individual spring. Reduction can be achieved.
In the above-described embodiment, since the knob 80 is installed in the lower part of the box body 20, the appearance design of the glove box 1 can be improved.
In the above-described embodiment, the box body 20 automatically pops out from the box storage body 10 when each rod rod 50 is operated in the unlocked state by the operation of the knob 80, so that the box body 20 can be easily pulled out.

Although the best mode for carrying out the present invention has been described above with reference to the drawings, this embodiment can be easily changed or modified without departing from the spirit of the present invention.
For example, by providing a stopper mechanism STP and a knob 80 on a drawer-type functional member (for example, a tray) provided on a console or the like, and providing a cam portion 18 on the console body, each rod rod 50 can be provided in the same manner as in the above-described embodiment. Can be operated in a locked state and an unlocked state.
