  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. 18 to 21, 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. 19A and 20, the lever 77 is inserted and arranged in the frame-shaped rod holding portion 73 of the rod 70 in a state where the lever 77 is not pushed in. Further, 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. 20).

  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. 18 and 21), 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. 19A and 20).

  Next, the effect of the locking device 10 composed 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. 16C), 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 a direction in which the contact portion 81 of 80 is brought into contact with the magnet attracting member 5 (see FIGS. 14 and 20). 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 retracting holding of the rod 70 is released will be described (see FIGS. 19A and 20).

  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. 20).

  At this time, in the lock device 10, the pair of movable lock members (rods 70 and 80) are connected to the separate rotors 50 and 60, respectively, so as to slide without being affected by the operation of the other movable lock member. Therefore, for example, when the lid 7 is closed with respect to the opening 2 of the glove box 1, even if one movable locking member stops without being completely coupled to the corresponding locking portion, the other movable The locking member can be completely coupled to the corresponding locking part without being affected by it. As a result, it is possible to reduce the occurrence of a state in which one movable lock member is hooked to one lock portion and the other movable lock member is not coupled to the other lock portion. The inconvenience of opening carelessly can be avoided.

  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 inclined surfaces 55 and 65 of both rotors 50 and 60, that is, the pushing convex portion 45 abuts on the cam inclined surfaces 55 and 65 and applies the operating force. As a result, the rotational force of the torsion coil spring 15 is rotated so that the lowest ends of the cam inclined surfaces 55 and 65 of the rotors 50 and 60 are separated from each other (see FIG. 16A). ), The engagement portion 71 of the rod 70 is slid in a direction not engaged with the lock portion 3 to be unlocked, and the magnet 83 of the contact portion 81 of the rod 80 has its magnetic attraction surface 83a and a magnet attraction member. 5 slides in a direction away from the magnet attracting member 5, the magnet 83 and the magnet attracting member 5 are separated from each other, and the contact lock by the magnetic attraction is released (FIG. 21). Irradiation), it is possible to open the lid 7 from the opening 2 of the glove box 1 (see Figure 1).

  At this time, in this embodiment, the pushing convex portion 45 of the operation member 40 has an arc shape, and the cam slopes 55 and 65 of the pair of rotors 50 and 60 pressed against the pushing convex portion 45 are also the pushing convex portion 45. Therefore, the pushing force from the operation member 40 can be efficiently transmitted without waste, and the pair of rotors 50 and 60 can be smoothly rotated.

  In the locking device 10, as described above, the pushing protrusion 45 is provided on the operation member 40 side, and the receiving portion is provided on the rotor 50, 60 side, that is, the operation member 40 is a pair of rotors 50. , 60 is not limited to the type of pulling up the operation member (pull operation type), as long as it has a function of rotating the rotors 50, 60 by applying an operating force to the receiving portions 52, 63 provided in The operation member 40 can be applied to a type (push operation type) in which the operation member 40 is pushed in, and an operation member having a form suitable for an application location of the lock device 10 can be selected.

  Further, by appropriately selecting the shapes of the operation member 40 and the receiving portions 52 and 63 formed on the respective rotors 50 and 60, the moving amount (stroke amount) of one movable lock member and the other movable lock are selected. The movement amount (stroke amount) of the member can be appropriately changed according to the purpose. Note that the amount of movement of the pair of movable lock members does not need to be changed. Actually, although the rod 70 and the rod 80 in this embodiment slide independently of each other, the stroke amounts are substantially the same. .

  Furthermore, in this locking device 10, the cam member is not slid by the cam groove and the convex portion moving in the cam groove as in the side lock device of Patent Document 1, but on the operation member 40 side. Since the push-in convex portion 45 is provided and the receiving portion is provided only on the rotor 50, 60 side, the structure can be simplified, and the pair of rotors 50, 60 can be reliably rotated by operating the operation member 40. Can be made.

  Further, in this embodiment, when the operation member 40 is pushed in with the opening 2 of the glove box 1 closed by the lid 7, the engagement portion 71 of the rod 70 is slid in a direction not engaged with the lock portion 3. As described above, the base end portion 77 b of the lever 77 is engaged with the lower end portion 73 a of the rod holding portion 73, and the engaging portion 71 of the rod 70 is held in a state where it is not engaged with the lock portion 3 ( 19 (b) and FIG. 21), when the lid 7 is pushed again into the opening 2 of the glove box 1, the lid 7 is not brought into contact with the inner surface of the opening 2 of the glove box 1 and the pushing resistance is reduced. Can be closed smoothly.

  Further, in this embodiment, the first rotor 50 and the second rotor 60 are coaxially arranged by inserting the rotating shaft 33 of the housing 20 into the cylindrical portion 51 of the first rotor 50 and the bearing portion 62 of the second rotor 60. (See FIGS. 13, 15 and 16), the locking device 10 can be made compact, and the receiving parts 52 and 63 of the pair of rotors 50 and 60 can be brought close to each other to operate the operating member. 40 makes it easy to press the receiving portions 52 and 63 of the respective rotors 50 and 60.

  In this embodiment, as shown in FIGS. 7, 13 and 16, etc., the torsion coil spring 15 which constitutes the urging means has one end 17 engaged with the first rotor 50 and the other end. 18 is composed of one member locked to the second rotor 60, and the abutting portion 81 of the rod 80 is attracted to the magnet so that the engaging portion 71 of the rod 70 is engaged with the locking portion 3. The rotors 50 and 60 are urged to rotate so as to be in contact with the member 5. As described above, since the pair of rotors 50 and 60 can be rotationally biased by the single torsion coil spring 15, the manufacturing cost of the locking device 10 can be reduced.

  Furthermore, in this embodiment, the torsion coil spring 15 that constitutes the urging means has a winding part 16, and the winding part 16 receives the receiving part 52 of the first rotor 50 and the receiving part of the second rotor 60. Since the torsion coil spring 15, the first rotor 50, and the second rotor 60 are arranged coaxially with respect to the rotation shaft 33 of the housing 20 (FIGS. 13 and 15). Further, the locking device 10 can be further downsized while ensuring a long winding length of the winding portion 16 of the torsion coil spring 15.

  Further, as shown in FIG. 16A, when the pair of rotors 50 and 60 rotate, the winding portion 16 of the torsion coil spring 15 disposed on the outer periphery thereof has a similar shape from the expanded circular state. Therefore, the diameter is reduced in a distorted state. However, in this embodiment, 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, so that the operating member 40 is pushed in to receive the receiving portion 52. , 63 when the pair of rotors 50, 60 rotate in a direction away from each other, the winding portion 16 of the torsion coil spring 15 is in sliding contact with the outer peripheral surfaces of the receiving portions 52, 63 as shown in FIG. Thus, the diameter of the winding part 16 can be reduced with relatively little distortion. As a result, when both the rotors 50 and 60 are returned to rotation by the rotational biasing force of the torsion coil spring 15, the rotation can be returned quickly and smoothly.
