Description

  The present invention relates to a lock mechanism that is provided on one of two relatively moving structural bodies and that regulates relative movement in a close posture where both structural bodies approach each other.

  In many vehicles, a glove box is provided in front of the passenger seat in the instrument panel (see, for example, Patent Document 1). As shown in FIG. 11, the glove box 20 has a lid portion 22 and an article storage portion provided on the back side of the lid portion 22, and the lower portion of the article storage portion rotates with respect to the instrument panel 10. Supported as possible. The glove box 20 is disposed in the lid portion 22 so that the article storage portion is housed in the installation portion 12 provided in the instrument panel 10 and does not move in a closed posture in which the installation portion 12 is closed by the lid portion 22. The rotation is restricted by the lock mechanism 100 (FIG. 11A).

  The lock mechanism 100 includes an operation knob (not shown) that faces the front side of the lid portion 22 and a rod 102 that can be moved forward and backward in the left-right direction. The lock mechanism 100 rotates the glove box 20 in a closed posture by inserting the tip of the rod 102 protruding outward from the side surface of the lid portion 22 into the engagement hole 16 established in the instrument panel 10. It is regulated. The rod 102 urged in the direction protruding outward from the side surface of the lid portion 22 moves so as to retreat from the engagement hole 16 by opening the operation knob, whereby the rod 102 is removed from the engagement hole 16. A rotational displacement of the glove box 20 to the open posture is allowed. Then, when the glove box 20 is closed from the open posture, the tip of the rod 102 is pressed against the instrument panel 10 and is rotated and displaced while the rod 102 is moved to the disengagement position against the urging force ( When the tip of the rod 102 reaches the engagement hole 16 in FIG. 11B, the rod 102 is inserted into the engagement hole 16 by urging.

  As shown in FIG. 11 (a), a cushion rubber 104 is attached to the back surface of the lid portion 22, and the lock mechanism 100 is pressed against the instrument panel 10 so as to compress the cushion rubber 104 in the closed position. By restricting the rotation, the play of the glove box 20 is prevented by the elasticity of the cushion rubber 104. For this reason, when closing the glove box 20 from the open position, as shown in FIG. 11B, the glove box 20 is pressed against the instrument panel 10 to move the rod 102 to the disengagement position against the bias, The cushion rubber 104 is pressed against the instrument panel 10 and compressed. That is, since the elasticity of the cushion rubber 104 acts in the direction opposite to the direction in which the glove box 20 is closed, there is a difficulty in that the operation load when closing the glove box 20 is increased. In recent years, in order to prevent rattling of the glove box 20 more reliably, the rod 102 is strongly engaged with the engagement hole 16 by increasing the degree of compression of the cushion rubber 104 in the closed posture. . Therefore, it is difficult to achieve a balance between reducing the operation load when closing the glove box 20 and preventing rattling in the closed posture in which the tip of the rod 102 is engaged with the engagement hole 16.

  The lock mechanism 40 according to the embodiment includes a lock member 42 disposed so as to be movable forward and backward so as to be engaged and disengaged with respect to the engagement hole 16, and a direction (engagement) of the lock member 42 with the engagement hole 16 Urging means 44 for urging in the direction) and operating means 46 for moving the lock member 42 in the direction (withdrawal direction) to retract from the engagement hole 16. The lock mechanism 40 includes a pair of lock members 42 and 42 formed in a bar shape extending substantially horizontally (see FIG. 2), and the lock members 42 and 42 are configured to move in opposite directions. Each lock member 42 is connected at one end in the longitudinal direction to the operating means 46 in the mechanism arrangement portion 28, and the other end in the longitudinal direction (referred to as an engagement end portion 43) is opened on the side wall surface of the mechanism arrangement portion 28. It protrudes outward from the vent 32 formed. The lock member 42 is disposed so as to be movable back and forth in the left-right direction, and the projecting dimension of the engagement end 43 from the through hole 32 is changed. Each lock member 42 has an engagement position (see FIG. 5) where the engagement end 43 projects to a position where the engagement end 43 can engage with the engagement hole 16, and the engagement end 43 engages with the engagement hole 16. It is configured to move forward and backward between the disengaged position (see FIG. 6) that has retreated to the disengaged position. In the locking mechanism 40, the front surface (surface facing the opening direction) of the engaging end portion 43 inserted into the engaging hole 16 and the opening edge on the front side (opening direction front side) of the engaging hole 16 are the opening direction of the glove box 20. The movement in the opening direction of the glove box 20 is regulated by being overlapped with the hook.

  As shown in FIGS. 3 and 4, the operation means 46 is supported by a base 48 fixed to the operation recess 30 so as to be capable of posture displacement, and is arranged to face the front side from the operation recess 30. A linkage member 54 is provided on the inner side of the mechanism arrangement portion 28 so as to be supported by the base 48 so as to be displaceable. The operation knob 52 is rotatably supported by a pair of support shafts 49, 49 formed on the front surface of the base 48 so as to be separated from each other on the left and right sides, and a plate-like finger-hanging portion is disposed away from the base 48. The operation knob 52 is configured to rotate around a horizontal axis with both support shafts 49 and 49 as fulcrums, and a non-operation posture (see a solid line in FIG. 4) substantially aligned with the opening surface of the operation recess 30. The posture is displaceable between the operation posture and the operation posture tilted so that the lower part of the finger-hanging part is pulled out to the vehicle compartment R side (see the two-dot chain line in FIG. 4A). An elastic member 51 made of a torsion coil spring is disposed between the base 48 and the operation knob 52, and the operation knob 52 is urged toward the non-operation posture by the elastic member 51. A linking arm 53 is formed on the rear surface of the operation knob 52 so as to protrude rearward. The protruding end of the linking arm 53 is located inside the mechanism arrangement portion 28 through an opening 48 a formed in the base 48. It comes to face. The linkage arm 53 swings in the vertical direction as the operation knob 52 is displaced, and is configured to be displaced downward by performing a lock release operation to change the operation knob 52 from the non-operation posture to the operation posture.

  As shown in FIGS. 3 and 4, the linking member 54 is configured such that the rotating cylinder portion 54 a is fitted to the linking shaft 50 that is formed to protrude toward the mechanism arrangement portion 28 on the rear surface of the left edge of the opening 48 a in the base 48. It is supported so that it can rotate, and its posture is displaced around the front and rear axes. The linkage member 54 includes a first lever portion 55 that extends upward from the rotating cylinder portion 54a so as to be orthogonal to the rotation axis, and a second lever that extends downward from the rotation cylinder portion 54a so as to be orthogonal to the rotation axis. The first lever portion 55 and the second lever portion 56 are formed in a symmetrical relationship with the rotating cylinder portion 54a interposed therebetween. One end in the longitudinal direction (right end) of the left lock member 42 is rotatably connected to the extension end of the first lever portion 55, and the right lock member 42 is connected to the extension end of the second lever portion 56. One end (left end) in the longitudinal direction of the two is rotatably connected. Further, the linkage member 54 is formed with a linkage receiving portion 57 extending rightward from the rotary cylinder portion 54a so as to be orthogonal to the rotation axis between the first lever portion 55 and the second lever portion 56. The extended end of the linkage receiving portion 57 faces the rear of the opening 48a. Further, the extended end of the linkage receiving portion 57 is arranged so as to overlap the displacement locus of the linkage arm 53 accompanying the posture displacement of the operation knob 52 from the non-operation posture to the operation posture. An urging means 44 comprising a torsion coil spring is disposed between the base 48 and the linking member 54, and the urging means 44 urges the linking member 54 counterclockwise. The urging means 44 urges the linking member 54 so as to displace the lever portions 55 and 56 in the direction approaching the side of the passage 32 through which the lock member 42 connected to the extending end passes. It is comprised so that 42 may be biased toward an engagement position.

  The operation means 46 is configured such that the linkage receiving portion 57 contacts the lower side of the linkage arm 53 in a state where the operation knob 52 is in the non-operation posture and the lock member 42 is in the engaged position (see FIG. 3 and FIG. 3). (See FIG. 4). The operation means 46 is pushed by the linkage arm 53 that is displaced downward in accordance with the unlocking operation of the operation knob 52 and the linkage receiving portion 57 is displaced downward, so that the linkage member 54 is biased by the biasing means 44. Counterclockwise rotation. Then, the clockwise rotation of the linkage member 54 displaces the lever portions 55 and 56 in the direction away from the through-hole 32 side through which the lock member 42 connected to the extending end passes, so that each lock member 42 is engaged. It is moved from the position toward the disengagement position. Further, when the operation knob 52 in the operation posture is released, the operation knob 52 is urged by the elastic member 51 to return to the non-operation posture, and the linkage arm 53 is displaced upward, thereby urging the urging means 44. Counterclockwise rotation of the linkage member 54 is allowed. Then, due to the counterclockwise rotation of the linkage member 54, the lever portions 55, 56 are displaced in a direction approaching the side of the passage 32 through which the lock member 42 connected to the extending end passes, so that each lock member 42 is engaged. It is moved from the mating release position toward the engagement position. That is, when the unlocking operation of the operation knob 52 is released, each lock member 42 is automatically returned from the engagement release position to the engagement position by the urging of the urging means 44.

  The lock mechanism 40 is capable of clockwise rotation displacement of the linkage member 54 in which the linkage receiving portion 57 is separated from the linkage arm 53 in a state where the operation knob 52 is in the non-operation posture. The lock member 42 is allowed to move to the disengagement position when the end portion 43 is pressed. At this time, since both the lock members 42 and 42 are moved by the rotation of the linkage member 54, the other lock member 42 is interlocked with the movement of the one lock member 42. When the glove box 20 is returned from the open position to the closed position, the lock mechanism 40 is locked by bringing the engaging end 43 into contact with the side wall 12a of the installation section 12 without unlocking the operation means 46. The member 42 can be moved to the disengagement position. In the closed position, the engagement end 43 overlaps the engagement hole 16 and the lock member 42 is released from the side wall 12 a of the installation portion 12, so that the lock member 42 is engaged by the urging force of the urging means 44. The engagement end portion 43 is inserted into the engagement hole 16 by being moved to the position. The engagement end 43 is formed with an engagement guide surface 43a that is inclined in the opening direction toward the front end side (see FIG. 6), so that the glove box 20 can be moved from the open position to the closed position. Accordingly, the lock member 42 can be smoothly moved from the engagement position to the engagement release position by the inclination of the engagement guide surface 43a that comes into contact with the side wall 12a.

  Next, the buffer means 60 disposed in the glove box 20 will be described. The lock mechanism 40 according to the embodiment includes a left shock absorber 60 corresponding to the left lock member 42 and a right shock absorber 60 corresponding to the right lock member 42. The left and right shock absorbers 60, 60 have the same basic configuration except that the arrangement is symmetrical, and will be described below with reference to the right shock absorber 60.

  As shown in FIGS. 5, 6, and 8, the buffer means 60 includes a buffer body 62 that can be moved forward and backward with respect to the instrument panel 10, and the buffer body 62 in conjunction with the forward and backward movement of the lock member 42. And link means 68, 70, 72 for moving the. The buffer body 62 is disposed so as to protrude from the upper part of the rear surface of the recumbent portion 27 toward the receiving surface portion 14 facing the recumbent portion 27 (see FIG. 2), and the glove box 20 and the instrument in a closed posture. It faces the surface facing the ment panel 10 (see FIGS. 5A and 7). The shock absorber 62 is disposed on the outer side of the through-hole 32 of the mechanism disposition portion 28 through which the lock member 42 passes and the engagement hole 16 with which the lock member 42 engages, and the engagement end 43 of the lock member 42. Is in contact with the receiving surface portion 14 on the outer side than the portion engaging with the engaging hole 16. The buffer body 62 is disposed on the opening direction side of the lock member 42 (front side in the movement direction from the closed position to the open position of the glove box 20), and the buffer body 62 and the lock member 42 are in the glove box in a side view. They are arranged in the 20 movement directions (front-rear direction) (see FIG. 7). That is, the receiving surface portion 14 (instrument panel 10) is sandwiched between the engagement end portion 43 of the lock member 42 engaged with the engagement hole 16 and the buffer body 62.

  The buffer body 62 moves forward and backward so that the projecting dimension from the rear surface of the horizontal flange portion 27 changes, and a forward position (see FIG. 5) where the buffer body 62 can come into contact with the receiving surface portion 14 in a closed posture. It moves between the retracted position (see FIG. 6B) that has retreated so as not to contact. The buffer 62 is configured to move forward and backward in the moving direction of the glove box 20, and is moved forward when displaced in the closing direction of the glove box 20, and moved backward when displaced in the opening direction of the glove box 20. It becomes. Thus, the buffer body 62 moves forward and backward in a direction different from the lock member 42 that moves forward and backward in the left-right direction intersecting the movement direction of the glove box 20, and the forward and backward movement directions of the buffer body 62 and the lock member 42 are different. Configured to intersect. The movement direction of the glove box 20 is a tangential direction of the rotation locus of the glove box 20 if it is a rotational displacement with the support shafts 21 and 21 as fulcrums as in the glove box 20 of the embodiment. If the box 20 is slid and displaced with respect to the instrument panel 10, it refers to the sliding direction of the glove box 20.

  The buffer body 62 is rearward from the rear surface of the recumbent portion 27 in the advanced position rather than the planar projection interval W1 between the recumbent portion 27 and the receiving surface portion 14 in the closed posture (see FIG. 5A). The projecting dimension D1 to the side (see FIG. 5B) is set to be large (W1 <D1). Accordingly, the buffer body 62 is configured to elastically contact the receiving surface portion 14 in a state where the engagement end portion 43 of the lock member 42 is engaged with the engagement hole 16 in the closed posture. The buffer body 62 urges the glove box 20 in a direction away from the receiving surface portion 14 (opening direction) while in contact with the receiving surface portion 14 facing the moving direction in the closed posture. Further, the buffer body 62 has a projecting dimension D2 (from the rear surface of the lateral flange portion 27 to the rear side in the retracted position, rather than the planar projection interval W1 between the lateral flange portion 27 and the receiving surface portion 14 in the closed posture. 6B) is set to be small (W1> D1). That is, in the state of being in the retracted position, the buffer body 62 does not come into contact with the receiving surface portion 14 even when the glove box 20 is in the closed posture.

  The buffer body 62 is basically composed of a cylindrical holder 64 and a cylindrical abutting portion 66 fixed to the holder 64, and the holder 64 is disposed inside the lateral flange portion 27. The abutment portion 66 protrudes rearward from the communication port 34 provided on the rear surface of the lateral flange portion 27 (see FIGS. 5 to 7). The holder 64 is held so as to be movable in the front-rear direction (moving direction of the glove box 20) between a pair of left and right holding pieces 36, 36 that are formed to protrude rearward from the rear surface of the front plate 22a that forms the horizontal flange portion 27. Yes. The contact portion 66 is made of a material having elasticity such as rubber, and the protruding end surface of the contact portion 66 receives the glove box 20 in the closed position and the buffer body 62 in the advanced position. It comes into contact with the surface portion 14. Here, the buffer 62 in the forward position is dimensioned so as to interfere with the receiving surface portion 14 in the closed posture of the glove box 20, but the abutting portion 66 interferes with the receiving surface portion 14 under the contact. By elastically deforming by the size, insertion of the engagement end 43 of the lock member 42 into the engagement hole 16 is allowed. Thereby, the buffer body 62 in the forward position applies a reaction force to the glove box 20 in the opening direction away from the instrument panel 10 in the closed posture. The buffer 62 urges the glove box 20 in the closed posture in a direction in which the engagement end portion 43 of the lock member 42 is caught in the engagement hole 16. That is, in the glove box 20 in the closed posture, the front surface of the engagement end portion 43 of the lock member 42 is pressed against the front opening edge of the engagement hole 16 facing in the opening direction.

  The buffer means 60 is configured to move the buffer body 62 in the direction of retreating from the receiving surface portion 14 by the link means 68, 70, 72 as the lock member 42 moves from the engagement position to the engagement release position. (See FIG. 6). Further, the buffer means 60 of the embodiment moves the buffer body 62 in the direction approaching the receiving surface portion 14 by the link means 68, 70, 72 as the lock member 42 moves from the engagement release position to the engagement position. It is configured as follows. The buffer means 60 holds the buffer body 62 in the advanced position by the link means 68, 70, 72 with the lock member 42 in the engaged position (see FIG. 5), and the lock member 42 is in the disengaged position. In this state, the buffer body 62 is held in the retracted position by the link means 68, 70, 72 (see FIG. 6B).

  As shown in FIG. 8, the link means is provided on the lock member 42, and interlocked with the interlock member 68 that moves in the same direction as the lock member 42 in conjunction with the forward / backward movement of the lock member 42, and 62 includes a shaft portion 70 provided on any one of 62, and a guide portion 72 provided on any one of the interlocking portion 68 and the buffer body 62 and having guide surfaces 73 a and 73 b for guiding the shaft portion 70. . In the embodiment, the shock absorber 62 is provided with the shaft portion 70, and the guide portion 72 is provided at the end of the interlocking portion 68. The linking means is guide surfaces 73a and 73b extending so as to obliquely intersect the moving direction of the interlocking portion 68 in the guiding portion 72 that is displaced with the movement of the interlocking portion 68. The shaft part 70 is guided in the moving direction (front-rear direction) of the glove box 20 intersecting with the left-right direction.

  The interlocking portion 68 is formed so as to extend along the locking member 42 after branching so as to extend forward from the locking member 42 in the mechanism disposing portion 28, and the extending end portion of the interlocking portion 68 is a locking member. It is arrange | positioned rather than 42 (opening direction of the glove box 20) (refer FIG. 5 and FIG. 7). Further, the extending end portion of the interlocking portion 68 is disposed on the inner side of the lateral flange portion 27 and is located on the outer side of the engaging end portion 43 of the lock member 42. Further, the extended end portion of the interlocking portion 68 is formed with a pair of extending pieces 69 and 69 that are bifurcated and are opposed to each other in the vertical direction. Both formed holding pieces 36, 36 are sandwiched vertically (see FIG. 7). Each extension piece 69 is formed with a hole-like guide portion 72 that penetrates vertically, and an upper shaft portion 70 that is formed to protrude upward on the upper surface of the holder 64 is formed on the upper extension piece 69. In addition to being inserted into the portion 72, the lower shaft portion 70 formed to protrude downward on the lower surface of the holder 64 is inserted into the guide portion 72 formed in the lower extending piece 69. Thus, the buffer body 62 has the holder 64 held by the left and right holding pieces 36, 36, and the upper and lower shaft portions 70, 70 protruding from between the left and right holding pieces 36, 36 move the holder 64 up and down. The upper and lower guide portions 72, 72 formed on the extending pieces 69, 69 sandwiched therebetween are correspondingly engaged.

  As shown in FIGS. 5 and 6, the guiding portion 72 is inclined so as to be biased in a direction (front side) away from the receiving surface portion 14 toward the outer side (from the disengagement position to the engagement position). The receiving surface portion is constituted by the guiding surface 73a and the forward regulating surface 74a that is connected to the side (front side) away from the receiving surface portion 14 of the backward guiding surface 73a and extends in the forward / backward moving direction (left / right direction) of the interlocking portion 68. A 14 side surface (rear surface) is defined. The guiding portion 72 is connected to the forward guiding surface 73b formed in parallel to the backward guiding surface 73a and the side (front side) away from the receiving surface portion 14 of the forward guiding surface 73b and is parallel to the forward regulating surface 74a. A surface (front surface) on the side away from the receiving surface portion 14 is defined by the retreat regulating surface 74b formed on the front surface. The guide portion 72 guides the shaft portion 70 back and forth at an inclined portion defined by a backward guide surface 73a and a forward guide surface 73b extending so as to intersect the forward and backward movement direction of the lock member 42. Yes. Further, in the linear portion defined by the forward restriction surface 74a and the backward restriction surface 74b in the guide portion 72, the movement of the shaft portion 70 in the front-rear direction is restricted. In addition, the width | variety of the guidance | induction part 72 is set according to the external dimension of the axial part 70 formed in the column shape.

  The link means is configured such that the buffer body 62 is in the forward position in a state where the shaft portion 70 is located at the end portion on the receiving surface portion 14 side (rear side) in the inclined portion of the guide portion 72 (see FIG. 5). At this time, when the shaft portion 70 abuts on the forward guiding surface 73b, the movement of the shock absorber 62 in the direction away from the receiving surface portion 14 (front side) is restricted, and the shaft portion 70 abuts on the backward guiding surface 73a. Thus, the movement of the buffer body 62 in the direction approaching the receiving surface portion 14 (rear side) is restricted. The link means displaces the guide portion 72 as the interlocking portion 68 moves from the engagement position to the disengagement position, so that the shaft portion 70 in the inclined portion of the guide portion 72 is moved by the backward guide surface 73a. It moves in the direction away from 14 (front side) (see FIG. 6). Further, the link means displaces the guide portion 72 as the interlocking portion 68 moves from the disengagement position to the engagement position, so that the shaft portion 70 in the inclined portion of the guide portion 72 is moved by the forward guide surface 73b. It moves in a direction approaching the receiving surface part 14 (rear side). The link means does not fluctuate the shaft portion 70 even if the interlocking portion 68 (lock member 42) moves back and forth in a state where the shaft portion 70 is positioned on the straight portion of the guide portion 72 (FIG. 6 ( b)). Thus, the buffer means 60 holds the buffer body in the forward position corresponding to the lock member 42 in the engagement position, and the buffer body 42 moves from the engagement position to the engagement release position of the lock member 42. 62 is configured to move from the forward position to the reverse position. The buffer 60 holds the buffer 62 in the retracted position corresponding to the lock member 42 in the disengagement position, and the buffer body 42 moves from the disengagement position to the engagement position of the lock member 42. 62 is configured to move from the retracted position to the advanced position.

  According to the lock mechanism 40, the front surface of the engagement end 43 is inserted by inserting the engagement end 43 of the lock member 42 held in the engagement position by the biasing means 44 into the engagement hole 16. Is caught by the front opening edge of the engagement hole 16, and the rotation of the glove box 20 in the closed position in the opening direction can be restricted. In a state where the lock member 42 is in the engagement position where the glove box 20 is closed and the engagement hole 16 is engaged, the buffer body 62 is held at the forward movement position by the link means 68, 70, 72 and is held on the receiving surface portion 14. Elastic contact. Since the buffer body 62 protrudes from the rear surface of the lateral flange portion 27 toward the receiving surface portion 14 so as to interfere with the receiving surface portion at the advanced position, the reaction force by the contact portion 66 elastically deformed by the contact with the receiving surface portion 14. Is added to the glove box 20 in a direction away from the receiving surface portion 14. Accordingly, a force acts so as to press the engagement end 43 of the lock member 42 against the front opening edge of the engagement hole 16, so that the engagement end 43 and the front opening edge of the engagement hole 16 are in contact with each other. Is maintained. Further, the buffer body 62 interposed between the receiving surface portion 14 and the lateral flange portion 27 restricts the rotation of the glove box 20 to the rear side (direction approaching the receiving surface portion 14). Therefore, the lock mechanism 40 can restrict the movement of the glove box 20 in the front-rear direction (the direction of contact with and away from the receiving surface portion 14) by the buffer body 62 that elastically contacts the receiving surface portion 14, and thus the glove box 20 in the closed posture. Can be held without rattling.

  The lock mechanism 40 is in a closed position when the lock member 42 is moved from the engagement position to the disengagement position by the unlocking operation of the operation knob 52 so that the engagement end portion 43 comes out of the engagement hole 16. The glove box 20 is allowed to rotate in the opening direction. At this time, the lock mechanism 40 moves so that the interlocking portion 68 moves in the same direction as the lock member 42 moves from the engagement position to the engagement release position, so that the shaft portion 70 moves away from the receiving surface portion 14 on the backward guiding surface 73a. By being guided, the buffer body 62 is displaced to the retracted position. The lock mechanism 40 disengages the lock member 42 by the biasing means 44 when the unlocking operation of the operation knob 52 is canceled when the glove box 20 in an open position or the like is separated from the installation portion 12. Return from the position to the engaged position. The locking mechanism 40 has a receiving surface portion as the interlock member 68 moves in the same direction as the lock member 42 moves from the engagement release position to the engagement position, and moves outward (from the engagement release position to the engagement position). When the shaft portion 70 is guided by the forward guiding surface 73b inclined in the direction (front side) away from the shaft 14 so as to approach the receiving surface portion 14, the buffer body 62 is displaced to the forward position.

  When the glove box 20 is returned from the open position to the closed position, the engagement end 43 of the lock member 42 abuts against the side wall 12 a of the installation section 12, so that the lock member 42 urges the urging means 44. Against this, it is pushed away from the engagement position to the engagement release position. The locking mechanism 40 is guided so that the interlocking portion 68 moves in the same direction as the locking member 42 moves from the engaging position to the disengaging position, and the shaft portion 70 is separated from the receiving surface portion 14 by the backward guiding surface 73a. Thus, the buffer body 62 is displaced to the retracted position. Since the buffer body 62 in the retracted position has a projecting dimension smaller than the distance between the lateral flange portion 27 and the receiving surface section 14 in the closed position, the buffer body 62 receives the buffer body from the open position to the closed position. It does not contact the surface portion 14. Then, as the glove box 20 is displaced from the open posture to the closed posture, the engagement end portion 43 of the lock member 42 is inserted into the engagement hole 16 by the biasing means 44. The lock mechanism 40 is guided so that the interlocking portion 68 moves in the same direction as the lock member 42 moves from the disengagement position to the engagement position, and the shaft portion 70 approaches the receiving surface portion 14 by the forward guiding surface 73b. Thus, the buffer body 62 is displaced to the forward movement position. Thereby, in the closed position of the glove box 20 in which the engagement end portion 43 of the lock member 42 in the engagement position is engaged with the engagement hole 16, the shock absorber 62 in the advance position is elastically applied to the receiving surface portion 14. Abut.

  As described above, according to the lock mechanism 40, when the glove box 20 is returned from the open position to the closed position, the buffer body 62 does not come into contact with the receiving surface portion 14, and therefore the buffer body 62 is closed when the glove box 20 is closed. Does not become resistance. That is, the operation load at the time of closing the glove box 20 can be reduced as compared with the configuration in which the buffer body 62 is closed while being pressed. In addition, the locking mechanism 40 does not increase the operation load when closing the glove box 20 even if the interference dimension of the shock absorber 62 is set large, so that the shock absorber 62 is brought into a closed posture by elastic contact. The backlash of a certain glove box 20 can be more reliably reduced. Therefore, according to the lock mechanism 40, it is possible to achieve both the reduction of the operation load of the glove box 20 and the more reliable movement regulation of the glove box 20 without backlash.

Further, unlike the buffer means 80 of the modified example shown in FIGS. 9 and 10, the guiding portion 82 is not provided with the forward guiding surface, and the buffer body 62 is moved to the receiving surface portion 14 (forward position) by the elastic body 86 such as a coil spring. The structure which urges | biases toward may be sufficient. The elastic body 86 is inserted between the rear surface of the front plate 22a of the horizontal flange portion 27 and the holder 64 of the shock absorber 62, and always applies elasticity so that the shock absorber 62 protrudes from the rear surface of the horizontal flange portion 27. .

By being guided, the buffer body 62 is displaced to the retracted position. If the buffer means 80 cancels the unlocking operation of the operation knob 52, the lock member 42 returns to the engaged position by the biasing means 44 and the buffer body 62 moves forward by the biasing of the elastic body 86. Return to. The buffer means 80 of the modified example can apply not only the elasticity of the abutting portion 66 of the buffer body 62 but also the elasticity of the elastic body 86 in the closed posture.
