In addition, when the transmission gear support 117 is positioned upward (see FIG. 5), the lock arm 114 is prevented from lowering its tip below a predetermined position by the stopper 114A.

  Next, the operation of the embodiment of the present invention will be described.

  First, the operation when the drawer body 12 is pulled out from the state in which the drawer body 12 is stored in the housing 11 will be described.

  FIG. 4 shows a state in which the drawer body 12 is stored in the housing 11.

  In this state, the lock arm 114 is engaged with the lock groove 105 provided in the upper part of the movable portion 101, and the drawer body 12 is locked so as not to be pulled out from the housing 11.

  The transmission gear support 117 is positioned below, and the transmission gear 108 held by the transmission gear support 117 is engaged with the drive gear 107 and the power gear 109.

  The spring spring 110C is wound around the spring shaft A110A.

  In this state, when the operation knob 120 is pushed in (direction of arrow C in FIG. 5), the transmission gear support movable portion 113 is moved to the vehicle front side (arrow D in FIG. 5) via the operation bar 121 as shown in FIG. Direction). When the transmission gear support portion movable portion 113 moves to the front side of the vehicle, the pin 116A provided on the side surface of the transmission gear support portion 117 along the guide grooves 113A and 113B provided on the left and right side surfaces of the transmission gear support portion movable portion 113. 116B move upward, and the transmission gear support 117 also moves upward (in the direction of arrow E in FIG. 5). As a result, the transmission gear 108 moves upward, and the transmission gear 108 does not mesh with the drive gear 107 and the power gear 109.

  When the transmission gear support 117 moves upward by a predetermined distance, the engagement between the lock arm 114 and the lock groove 105 is released.

  As a result, the movable portion 101 starts to slide in the direction of arrow F in FIG. 5 due to the weight of the drawer body 12, and the drawer body 12 begins to be pulled out from the housing 11.

  At this time, the drive gear 107 meshes with the movable rack gear 103, but the drive gear 107 can freely rotate in the direction of the arrow KA in FIG. 12 is pulled out.

  When the drawer body 12 is pulled out to some extent, the drive gear 107 changes from the movable rack gear 103 to the movable rack gear 102 (see FIG. 6). Also in this case, since the drive gear 107 can freely rotate in the direction of the arrow KB in FIG. 6, the pulling body 12 is pulled out without the force of pressing the pulling out of the pulling body 12 acting.

  Since the movable rack gears 102 and 103 are movable in the sliding direction of the movable portion 101, when the drive gear 107 changes from the movable rack gear 103 to the movable rack gear 102, the gear mesh is adjusted, and the gear meshes. Smooth transitions can be made without losing power.

  When the drawer body 12 is fully pulled out, the gear connection knob 118 provided on the vehicle front side (left side in FIG. 7) of the movable portion 101 causes the transmission gear support portion movable portion 113 to move to the vehicle interior side (arrow in FIG. 7). (G direction), the transmission gear support part movable part 113 moves to the vehicle interior side. When the transmission gear support portion movable portion 113 moves to the vehicle interior side, the pin 116A provided on the side surface of the transmission gear support portion 117 along the guide grooves 113A and 113B provided on the left and right side surfaces of the transmission gear support portion movable portion 113. 116B move downward, and the transmission gear support 117 also moves downward (in the direction of arrow H in FIG. 7). As a result, the transmission gear 108 moves downward, and the transmission gear 108 meshes with the drive gear 107 and the power gear 109. At the same time, the operation bar 121 moves to the vehicle interior side (in the direction of arrow I in FIG. 7), and the operation knob 120 that has been pushed in returns to its original position.

  Next, the operation when the drawer body 12 is stored in the housing 11 from the state in which the drawer body 12 is pulled out from the housing 11 will be described.

  When the drawer body 12 is pulled out from the housing 11 and the operator pushes the drawer body 12 into the housing 11 (in the direction of arrow J in FIG. 8) from the state shown in FIG. Move forward (in the direction of arrow K in FIG. 8). Accordingly, the drive gear 107 is rotated in the direction of the arrow KB in FIG. 8 by the movable rack gear 102, and this rotation causes the transmission gear 108 to move in the direction of the arrow LA in FIG. 8, and the power gear 109 and the mainspring shaft A 110 A in FIG. Rotate in the direction. When the mainspring shaft A110A rotates in the direction of the arrow MA in FIG. 8, the mainspring spring 110C wound around the mainspring shaft A110A starts to be wound around the mainspring shaft B110B.

  When the operator stores the drawer body 12 in the housing 11 to some extent, the drive gear 107 is switched from the movable rack gear 102 to the movable rack gear 103 as shown in FIG. In this state, drive gear 107 rotates in the direction of arrow KA in FIG. 9, transmission gear 108 rotates in the direction of arrow LB in FIG. 9, and power gear 109 and mainspring shaft A110A rotate in the direction of arrow MB in FIG. At this time, the mainspring spring 110C wound around the mainspring shaft B110B begins to return to the mainspring shaft A110A. Therefore, the urging force causes the power gear 109, the transmission gear 108, and the drive gear 107 to rotate independently, and the operator pulls out the drawer body. Even if 12 is not pushed in, the movable part 101 moves to the front side of the vehicle (in the direction of arrow L in FIG. 9), and the drawer body 12 is stored in the housing 11.

  When the drawer body 12 is stored in the housing 11, the lock arm 114 is fitted into the lock groove 105, and the drawer body 12 is locked (see FIG. 4).

  FIG. 10 shows a schematic diagram of the first embodiment. In this embodiment, the above-described opening / closing control unit is applied to the drawer body 12 that is slid in parallel from the housing 11 and pulled out.

  Except for the movable portion 201 being linear, the structure is the same as that of the above-described embodiment, and the open / close control unit performs the same operation, and thus the description thereof is omitted.

In this embodiment, a fixed rack gear and a pinion gear are used instead of the movable rack gears 102 and 103, and the rotation of the drive gear when changing to the rack gear is kept smooth.
Since only the movable rack gears 102 and 103 are different from the above-described embodiment, only the structure and operation of this portion will be described.

  As shown in FIG. 11, the movable portion 101 includes a long hole 101 </ b> A in the center along the long direction.

  A fixed rack gear 122B is attached to the opening of the housing 11 on the upper surface of the long hole 101A (hereinafter referred to as the vehicle interior side). Further, a pinion gear 123 having a radius r1 (r1 <D1) is centered on a position at a predetermined distance D1 from the vehicle front side end portion of the fixed rack gear 122B on the vehicle front side (left side in FIG. 11) of the fixed rack gear 122B. The movable portion 101 is supported so as to be rotatable in the sliding direction. Here, the gear of the pinion gear 123 is set at an interval and a position where it can mesh with the drive gear 107.

  On the other hand, a fixed rack gear 122A is attached to the vehicle front side of the lower surface of the long hole 101A. Here, the vehicle interior side (right side in FIG. 11) end of the fixed rack gear 122A and the vehicle front side end of the fixed rack gear 122B are separated by a predetermined distance D2 (r1 <D2).

  When the drive gear 107 changes from the fixed rack gear 122A to the fixed rack gear 122B, it first meshes with the pinion gear 123 and then meshes with the fixed rack gear 122B. In this case, since the pinion gear 123 is rotatable, if the predetermined distances D1 and D2 and the radius r1 of the pinion gear are set so as to match the gear interval of the drive gear 107, the drive gear 107 is engaged with the gear. It is possible to change from the fixed rack gear 122A to the fixed rack gear 122B while maintaining smooth rotation without losing any trouble. The same applies when the drive gear 107 changes from the fixed rack gear 122B to the fixed rack gear 122A.

  As described above, in the embodiment of the present invention, when the drawer body is pushed and stored in the housing, the drawer body is automatically stored in the housing from the middle of storage, and the drawer body is locked in the storage state. Convenience can be improved.

  Further, since the drawer opening / closing mechanism includes a drawer locking mechanism, it is not necessary to provide a separate locking mechanism for locking the drawer.

  Further, since the drawer body is not provided with an opening / closing mechanism, the storage volume of the drawer body is not impaired, and the design is not impaired.

  Furthermore, the opening / closing mechanism can be housed in a gear case and can be used as a common part.

  As mentioned above, although the Example of this invention was explained in full detail with drawing, an Example is only an illustration of this invention and this invention is not limited only to the structure of an Example. Accordingly, it goes without saying that design changes and the like within a scope not departing from the gist of the present invention are included in the present invention.

  For example, based on the above-described embodiment and Example 2, it can be applied as a mechanism in which a movable rack gear and a fixed rack gear are combined.

  Furthermore, the application of the present invention is not limited to the vehicle glove box, and as long as the drawer body is pulled out from the housing, for example, a cup holder, an ashtray, a tray for a vehicle, a kitchen or furniture drawer, etc. Anything is applicable.
