  As shown in FIGS. 15 and 17, the first rotor 50 is disposed on the front side of the second rotor 60, and the housing 20 rotates on the cylindrical portion 51 of the first rotor 50 and the bearing portion 62 of the second rotor 60. By inserting the shaft 33, the first rotor 50 and the second rotor 60 are coaxially and rotatably mounted on the housing 20.

  Further, the winding portion 16 of the torsion coil spring 15 is disposed on the outer periphery of the receiving portion 52 of the first rotor 50 and the receiving portion 63 of the second rotor 60, and the one end portion 17 is the spring pull of the first rotor 50. The other end 18 is hooked by the hooking groove 53 b and is sandwiched and attached by the spring clamping portion 64 of the second rotor 60.

  In the above state, the cam inclined surface 55 of the first rotor 50 and the cam inclined surface 65 of the second rotor 60 are disposed so that the lowest ends thereof are opposed to each other, and the first rotor 50 and The second rotor 60 is urged to rotate by the torsion coil spring 15 so that the lowest ends of the cam inclined surfaces 55 and 65 are close to each other as shown by the arrows in FIG. ing. In addition, the 1st rotor 50 or the 2nd rotor 60 rotates independently of each other without being affected by the rotational operation of the other rotors.

  Next, the pair of rods 70 and 80 connected to the pair of rotors 50 and 60 will be described.

  As shown in FIG. 1, the pair of rods 70 and 80 has a rod shape extending linearly with a predetermined length. In this embodiment, the rod 80 is formed longer than the rod 70. Moreover, the front-end | tip part of the rod 70 has comprised the engaging part 71 in which the outer surface made the taper shape, and becomes a part engaged / disengaged to the lock | rock part 3 formed in the glove box 1 (FIG.23 and FIG.24). reference). Further, as shown in FIGS. 21 and 23, a frame-shaped rod holding portion 73 projects from the distal end portion of the rod 70 slightly toward the proximal end portion. On the other hand, as shown in FIG. 5, a magnet 83 is embedded on the back surface side of the contact portion 81 on the distal end side of the rod 80, and this is in contact with and joined to the magnet attracting member 5 disposed in the glove box 1. It is a part to do.

  The rod 70 and the rod 80 are respectively connected to the base end portions thereof, and are urged to rotate by the torsion coil spring 15 as indicated by the arrows in FIG. 16, the contact portion 81 of the rod 80 is brought into contact with the magnet attracting member 5 so that the engagement portion 71 of the rod 70 is engaged with the lock portion 3 as shown by the arrow in FIG. Both rods 70 and 80 are biased so as to be in the direction.

  As a result, the rod 70 is normally biased in the direction in which the engaging portion 71 engages with the lock portion 3 via the first rotor 60 that is rotationally biased by the torsion coil spring 15, as shown in FIG. 23. As described above, when the lid 7 is closed, the engaging portion 71 is engaged with the lock portion 3.

  On the other hand, in the rod 80, the magnet 83 provided at the contact portion 81 is attracted to the magnet attracting member 5 disposed in the glove box 1 by a magnetic force, and the magnetic attracting surface 5 a of the magnet attracting member 5 and the magnet 83. The magnet attracting member 5 and the magnet 83 are joined by contacting the magnetic attracting surface 83a with each other (see FIGS. 6 and 23), and in this state, the rod 80 is slid to apply an external force in the shearing direction. Can be peeled off (see FIG. 24).

  Then, when the operating member 40 is pushed into the housing 20, as described above, it rotates so that the lowest ends of the cam slopes 55, 65 of the rotors 50, 60 are separated from each other, and the rod 70 The engagement portion 71 slides in a direction not engaging the lock portion 3 to release the lock, and the magnet 83 of the contact portion 81 of the rod 80 is magnetically attracted by the magnetic attracting surface 83a and the magnet attracting member 5. By sliding in the direction away from the magnet attracting member 5 along the surface 5a, the contact lock by the magnetic attraction between the magnet 83 and the magnet attracting member 5 is released (see FIG. 24), and the opening 2 of the glove box 1 is released. The lid 7 is designed to open.

  In this embodiment, the rod 70 and the rod 80 form a “movable lock member”. In this embodiment, the engaging portion 71 of the rod 70 is engaged with and disengaged from the lock portion 3 and the abutting portion 81 of the rod 80 is brought into contact with and joined to the magnet attracting member 5. Another locking part 3 having a hole shape or a protrusion shape may be provided on the body so that the tip of the rod 80 is engaged or disengaged. Further, the pair of movable lock members are configured to be “releasably coupled to the lock portion”. This is because, as described above, the movable lock member is engaged with and disengaged from the lock portion, or the magnet attracting member. This includes the case where the movable lock member comes into contact with and joins.

  Further, in this embodiment, as shown in FIG. 1, the operating member 40, the first rotor 50 and the second rotor 60, and the rod 70 are attached to the opening 2 of the glove box 1 so as to be openable and closable. Located on one side of the driver. FIG. 1 shows the case where the vehicle is a right steering wheel.

  Furthermore, the locking device 10 of this embodiment has a holding means that holds the engaging portion 71 of the rod 70 in a retracted state so that the engaging portion 71 does not engage with the locking portion 3.

  As shown in FIGS. 21 to 24, the holding means includes a frame-like holding frame 75 disposed inside the rod insertion hole 9 a (see FIG. 3) of the box 9 constituting the lid 7, and the holding frame. 75, and a lever 77 that is rotatably mounted to 75. A tip 77a of the lever 77 has a pin shape, is inserted through a long hole 75a formed in the holding frame 75, and can swing within the long hole 75a. Further, as shown in FIGS. 22A and 23, the lever 77 is inserted and arranged in the rod-shaped rod holding portion 73 of the rod 70 with the base end portion 77 b in a state where the operation member 40 is not pushed. Furthermore, the base end 77b side is urged to rotate toward the panel 8 side of the lid 7 by an urging means (not shown) (see the arrow in FIG. 23).

  Then, the operation member 40 is pushed in from the state in which the opening 2 of the glove box 1 is locked in the closed state with the lid 7 and the engaging portion 71 of the rod 70 is biased in the direction of engaging with the locking portion 3. When the first rotor 50 is rotated and the engagement portion 71 of the rod 70 is slid in a direction not engaged with the lock portion 3, the lever 77 is rotated by the urging force of the urging means (not shown). The end portion 77b is engaged with the lower end portion 73a of the rod holding portion 73 of the rod 70 (see FIGS. 21 and 24), and the engagement portion 71 of the rod 70 is held in a state where it is not engaged with the lock portion 3. It has become.

  Further, when the lid 7 is pushed into the opening 2 of the glove box 1 in the above state, the tip 77a of the lever 77 is pressed against the periphery of the lock portion 3, and the lever 77 against the urging means (not shown). And the base end portion 77b is inserted into the rod holding portion 73, so that the holding state of the engaging portion 71 of the rod 70 is released, and the engaging portion 71 of the rod 70 becomes the locking portion 3 again. It is biased in the engaging direction (see FIGS. 22A and 23).

  Next, functions and effects of the lock device 10 and the operation device 11 made of the above-described components will be described.

  The locking device 10 includes a first rotor 50 so that the lowest end portions of the cam inclined surfaces 55 and 65 are brought close to each other by the torsion coil spring 15 before the opening 2 of the glove box 1 is closed. The second rotor 60 is urged to rotate (see FIG. 19C), and the rod 70 is engaged with the lock portion 3 in the direction of engaging the lock portion 3 via both rotors 50 and 60. Both rods 70 and 80 are biased in the direction in which the contact portion 81 of 80 is brought into contact with the magnet attracting member 5 (see FIGS. 16 and 23). In addition, the case where the base end part 77b of the lever 77 is inserted into the rod holding part 73 of the rod 70 and the pull-in holding of the rod 70 is released will be described (see FIGS. 22A and 23).

  In the above state, when the lid 7 is pushed to close the opening 2 of the glove box 1, the taper surface of the engaging portion 71 of the rod 70 is pressed against the inner surface of the opening 2, and the biasing force from the torsion coil spring 15 is pressed. Against this, the rod 70 is drawn toward the inside of the lid, and the contact portion 81 of the rod 80 enters the recess 4 (see FIG. 4) of the glove box 1.

  Thereafter, when the engaging portion 71 reaches the rectangular hole-shaped lock portion 3 of the opening 2, the first rotor 50 is rotationally biased by the torsion coil spring 15, and the rod 70 is pushed out toward the outside of the lid again. The engaging portion 71 engages with the lock portion 3, and the magnet 83 installed in the contact portion 81 of the rod 80 is attracted to the magnet attracting member 5 disposed in the concave portion 4 of the glove box 1 by magnetic force. Thus, the magnetic attracting surfaces 5a and 83a come into contact with each other, the magnet 83 and the magnet attracting member 5 are joined, and the opening 2 of the glove box 1 is locked in the closed state by the lid 7 (see FIG. 23).

  When maintaining the above-described locked state of the lid 7, the key cylinder 90 is rotated by a key (not shown), and the stopper 95 is slid through the key protrusion 93. As a result, the projecting piece 97 of the stopper 95 moves so as to cover the opening on the back side of the guide cylinder 31 having a long hole cross section (see FIG. 20), and the guide boss 47 inserted into the guide cylinder 31 is moved to this. Since it contacts, it can control that operation member 40 is pushed in any more, can prevent rods 70 and 80 from sliding by operation member 40, and can maintain a combined state with a lock part.

  As described above, the projecting piece 97 of the stopper 95 is brought into contact with the guide boss 47 inserted into the guide cylinder 31 and the pushing of the operation member 40 is restricted, so that the guide boss 47 loosely fitted in the long hole is used. The stopper 95 can restrict the movement to prevent the rattling, and the other guide boss 46 at a distant position is arranged in the arrangement direction of the pair of guide bosses 46 and 47 and the guide boss 46. Since it is inserted into the guide tube 30 having a cross-sectional shape that conforms to the outer periphery of the guide boss 46 in the orthogonal direction, the operation member 40 is restrained from being tilted and the operation member 40 is securely moved to the back of the housing 20. Can be pushed in.

  On the other hand, when opening the lid 7 from the opening 2 of the glove box 1, the operating member 40 is pushed into the housing 20. Then, the pushing convex portion 45 of the operating member 40 presses the cam slopes 55 and 65 of the rotors 50 and 60, respectively, and resists the rotational biasing force of the torsion coil spring 15, and the cam slopes of the rotors 50 and 60. Rotates so that the lowest ends of 55 and 65 are separated from each other (see FIG. 19A), and slides in a direction in which the engaging portion 71 of the rod 70 does not engage the locking portion 3 to release the lock. In addition, the magnet 83 of the contact portion 81 of the rod 80 slides in a direction away from the magnet attracting member 5 along the magnetic attracting surface 83a and the magnetic attracting surface 5a of the magnet attracting member 5, and the magnet 83 And the magnet attracting member 5 are separated from each other, the contact lock by magnetic attraction is released (see FIG. 24), and the lid 7 can be opened from the opening 2 of the glove box 1 (see FIG. 1).

  In the lock device 10 and the operation device 11, as described above, the guide bosses 46 and 47 provided on the operation member 40 protrude from the inside of the outer peripheral edge of the push-in portion 41, and they correspond to each other. Are inserted into the guide cylinders 30 and 31, respectively. Therefore, since the sliding grease applied between the guide bosses 46 and 47 and the guide cylinders 30 and 31 is held, a portion exposed when the operating member 40 is pushed in, for example, the inner periphery of the housing 20 In addition, it is possible to make it difficult for the grease to leak to the outer periphery of the pushing portion 41 of the operation member 40 (see FIG. 13B), and to prevent the grease from adhering to the operator's finger or hand.

  In this embodiment, the axis of the rotary shaft 33 protruding from the back side of the housing 20 is provided at a position displaced by a predetermined length L with respect to the axis of the guide cylinders 30 and 31. Therefore, (see FIG. 16), when the operating member 40 is mounted on the housing 20, the pushing convex portion 45 of the operating member 40 is positioned so as to substantially align with the cam inclined surfaces 55, 65 of the pair of rotors 50, 60. It is arranged. Therefore, when the pushing portion 41 is pushed to operate the operating member 40 with respect to the housing 20, the pushing force is efficiently applied to the cam inclined surfaces 55 and 65 of the pair of rotors 50 and 60 via the pushing convex portion 45. The pair of rotors 50 and 60 can be smoothly rotated to improve the operability when unlocking.

  Furthermore, in this embodiment, the inner periphery of the guide cylinder 30 corresponding to one guide boss 46 is the outer periphery of the guide boss 46 in the direction in which the pair of guide bosses 46 and 47 are arranged and in the direction perpendicular thereto. Since a suitable cross-sectional shape is formed (see FIG. 14), the guide boss 46 can be inserted into the guide cylinder 30 to position them. The inner circumference of the guide cylinder 31 corresponding to the other guide boss 47 is adapted to the outer circumference of the guide boss 47 in the direction perpendicular to the arrangement direction of the pair of guide bosses 46, 47 and Since the guide boss 47 is loosely fitted in the direction (see FIG. 14), there is a dimensional error in the distance between the pair of guide bosses 46, 47 and the pair of guide cylinders 30, 31. Even if it exists, while absorbing it, the other guide boss | hub 47 can be inserted in the guide cylinder 31 of a long hole-shaped cross section, and rotation control of the operation member 40 can be aimed at. Furthermore, since the dimensional error can be absorbed by the guide cylinder 31 having a long hole cross section, the sliding resistance of the guide boss 47 with respect to the inner periphery of the guide cylinder 31 can be reduced.

  In this embodiment, of the pair of guide cylinders 30, 31 provided in the housing 20, the guide cylinder 31 having a long hole cross section is disposed at a position closer to the driver's seat of the vehicle, and the other guide cylinder 30 is arranged at a position closer to the passenger seat than the guide cylinder 31. When the driver pushes the operation member 40, the driver often pushes one side of the operation member 40 in the direction close to the driver's seat side. In this case, the driver is given to the push portion 41 of the operation member 40. The pushing force acts obliquely with respect to the pushing direction, and the operation member 40 is pushed obliquely. Even in such a case, in this embodiment, since one guide boss 46 is adapted to the guide cylinder 30 and the other guide boss 47 is loosely fitted to the guide cylinder 31, the operation member 40 Is pushed diagonally, the guide boss 46 is supported by the guide cylinder 30, while the guide boss 47 appropriately moves within the guide cylinder 31, so that the sliding resistance when the operation member 40 is pushed in is reduced. The operation member 40 can be pushed in smoothly.

  Further, in this embodiment, the retaining pieces 46a, 47a provided on the outer circumferences of the respective guide bosses 46, 47 are provided on the side of the corresponding guide cylinders 30, 31 on the insertion ports 30c, 31c side of the guide bosses 46, 47. Since the guide bosses 46 and 47 are inserted into the guide cylinders 30 and 31, the operating member 40 can be prevented from being detached from the housing 20. it can. Further, since the retaining pieces 46a and 47a slide into the groove portions 30a and 31a formed in the corresponding guide cylinders 30 and 31 (see FIG. 17), the sliding resistance can be reduced, and Since the grease enters and is held in the slits 48 that form the groove portions 30a and 31a and the retaining pieces 46a and 47a, the grease leaks to the inner periphery of the housing 20, the outer periphery of the pushing portion 41 of the operation member 40, and the like. This can be prevented more reliably.
