  The switching means 20 moves the slide bar 27 slidable with respect to the slide base 22 and the rear stopper gear 18 so as to be able to approach and separate from the one pinion gear 15 as the slide bar 27 slides. The rotating member 28 and the urging spring 29 and a lever 30 for sliding the slide bar 27 with respect to the slide base 22 are configured.

  The slide bar 27 is provided below the holding plate 23 along the slide direction. A second rectangular hole 32 is formed in the engaging portion 31 that bends toward the slide base 22 at one end in the longitudinal direction. Yes. Further, a spring accommodating groove 33 extending in the longitudinal direction is formed at a substantially central portion of the slide bar 27, and protrudes toward the slide base 22 at the front end of the spring accommodating groove 33 and the end is folded forward. A bent spring engaging portion 34 is provided. An L-shaped guide groove 35 extending from the center in the width direction of the slide bar 27 to one side and extending rearward from a predetermined position is formed on the rear side of the spring housing groove 33, and one support groove The rotating shaft 17b of the stopper gear 17 to be inserted into 24 is inserted. Further, a rectangular hole 36 is formed on the rear side of the guide groove 35, and the rotation shaft 18b of the stopper gear 18 inserted into the support groove 25 is inserted. The rectangular hole 36 has such a size that the other support groove 25 is always included in a plan view even when the slide bar 27 slides. Further, the slide bar 27 is provided with a contact portion 37 that protrudes outward from one side in the width direction around the front end of the rectangular hole 36 and extends forward from a predetermined position. The abutting portion 37 is formed to be outside the holding plate 23, and its tip is bent perpendicularly to the holding plate 23 side.

  Such a slide bar 27 is provided so that the slide base 22 slide bar 27 is parallel to the slide base 22 via the first support 38 and the second support 39. The first support tool 38 and the second support tool 39 hold the slide bar 27 slidably with respect to the slide base 22 and the holding plate 23, and support both ends of the slide bar 27. Further, the first support member 38 and the second support member 39 are fixed to the slide bar 27 by screws or the like, and one screw fixing the second support member 39 has, for example, a shaft portion. A long screw 40 is used.

  The slide bar 27 is connected to the holding plate 23 by a coil spring 41. The coil spring 41 is accommodated in the spring accommodating groove 33 of the slide bar 27, and one end is engaged with the spring engaging portion 34, and the other end is a locking hole of the fixing pin 26 provided in the holding plate 23. 26b is provided to be engaged. By doing so, the slide bar 27 is biased toward the holding plate 23 in the sliding direction.

  The rotating member 28 is rotatably held on the rotating shaft 16 b of one pinion gear 16 on the back surface side of the holding plate 23. The rotating member 28 includes a central portion 28a attached to the rotating shaft 16b, a protruding portion 28b protruding in a direction opposite to each other, and a protruding portion 28c, and is perpendicular to the rotating shaft 16b of the pinion gear 16. It is attached with. The protrusion 28c is formed to have a length longer than that of the protrusion 28b, and is locked from the inner side to the rotation shaft 18b of the stopper gear 18 inserted into the rear support groove 25. Further, if the abutting portion 37 of the slide bar 27 is projected to the slide base 22 side with respect to the projecting portion 28c of the rotating member 28, the abutting portion 28c contacts the projecting portion 28c of the rotating member 28 simultaneously with the sliding of the slide bar 27. It becomes possible.

  The biasing spring 29 is externally mounted on one of the rear connection bolts 44 of the connection bolts 44 that connect the slide base 22 and the holding plate 27 on the back surface side of the holding plate 23. This urging spring 29 has a loop portion wound around the axis of the connecting bolt 44 in the center, and projects both end portions outward so as to be V-shaped in plan view. Of these, one end 29 b is locked to the rotating shaft 18 b of the rear stopper gear 18, and the other end 29 c is locked to the screw 40 of the second support tool 39. Thus, the rear stopper gear 18 is urged toward the pinion gear 16 which is not always meshed.

  The lever 30 is formed by bending, for example, a rectangular plate so as to have a substantially square shape when viewed from the side. The lever 30 has a handle portion 30b that bends toward the other end at one end, and the slide base 22 at the other end. The insertion part 30c which can be inserted in the 1st rectangular hole 21 and the 2nd rectangular hole 32 of the slide bar 27 is provided. Further, the lever 30 has a support shaft through hole 30d penetrating in the width direction at a bent portion thereof, and is supported by a mounting portion 43 that is fixed to the surface side of the slide base 22 and attaches the slide base 22 to the armrest 5 side. The cylindrical support shaft 42 inserted into the shaft through hole 30d is rotatably supported. Therefore, when the lever 30 is rotated, the slide bar 27 can be slid.

Next, the movement of the slide lock mechanism 10 will be described in detail.
First, when the slider 12 is in a locked state with respect to the base 11, as shown in FIG. 2, the pair of stopper gears 17 and 18 are simultaneously meshed with the pair of pinion gears 15 and 16. That is, the front stopper gear 17 inserted in the support groove 24 and the guide groove 35 is positioned at the center of the slider 12 by the slide bar 27 being urged toward the holding plate 23 in the sliding direction by the coil spring 41. Thus, the pair of pinion gears 15 and 16 are engaged with each other. The rear stopper gear 18 inserted into the support groove 25 and the rectangular hole 36 is positioned at the center of the slider 12 by the rotation shaft 18b being urged by the urging spring 29, and a pair of pinions The gears 15 and 16 are engaged with each other. By doing so, the rotation of the pinion gears 15 and 16 with respect to the racks 13 and 14 is restricted, and the stopped state of the slider 12 is maintained.

  In order to move the slider 12, the lever 30 is first lifted upward as shown in FIG. Then, the insertion portion 30c of the lever 30 is engaged with the second rectangular hole 32 of the slide bar 27, and the slide bar 27 is slid forward against the urging force of the coil spring 41, whereby a pair of stopper gears 17 and 18 are provided. Is turned in a predetermined direction. That is, when the slide bar 27 slides, the rotating shaft 17b of the front stopper gear 17 moves in the support groove 24 while being guided by the guide groove 35, and when the slide bar 27 is positioned from the base portion to the end portion of the support groove 24, the guide groove It is located at the corner of the 35 L-shape. Then, by sliding the slide bar 27 further forward, the rotating shaft 17b is held on the base part of the support groove 24 and the end part side of the guide groove 35. As described above, when the rotation shaft 17b of the stopper gear 17 moves in the support groove 24 while being guided by the guide groove 35, the stopper gear 17 is engaged with one pinion gear 15 while being centered on the rotation shaft 15b of the pinion gear 15. And turn around the pinion gear 15. In this way, the stopper gear 17 is separated from the other pinion gear 16 and the meshing engagement with the pinion gear 16 is released, and the pinion gear 15 can be rotated with respect to the rack 13. The stopper gear 17 that is separated from the other pinion gear 16 is always in mesh with the one pinion gear 15 and therefore rotates with the rotation of the pinion gear 15.

  At the same time, as the slide bar 27 slides, the tip of the abutting portion 37 of the slide bar 27 abuts on the protruding portion 28c of the rotating member 28, so that the rotating member 28 is shown in FIGS. By rotating clockwise, the rotating shaft 18b of the rear stopper gear 18 meshed with the pair of pinion gears 15 and 16 is moved toward the rack 14 along the support groove 25 while resisting the biasing force of the biasing spring 29. Move. At this time, the stopper gear 18 turns around the pinion gear 16 around the rotation shaft 16 b of the pinion gear 16 while meshing with the other pinion gear 16. By doing so, the stopper gear 18 is separated from the one pinion gear 15 and the meshing engagement with the pinion gear 15 is released, and the other pinion gear 16 can be rotated with respect to the rack 14. The stopper gear 18 separated from the one pinion gear 15 is always meshed with the other pinion gear 16 and thus rotates with the rotation of the pinion gear 16. The slider 12 slides when the pinion gear 15 and the stopper gear 17 and the pinion gear 16 and the stopper gear 18 are rotating in mesh.

  In this way, by making the stopper gears 17 and 18 not simultaneously mesh with the pair of pinion gears 15 and 16 by the slide bar 27, the rotation restriction of the pair of pinion gears 15 and 16 is released, and the slider 12 can slide along the racks 13 and 14.

  In order to stop the moved slider 12 at a desired position, when the lifting of the lever 30 is released at the position to be stopped, the slide bar 27 is pulled back with the elastic return of the coil spring 41, and the guide groove 35 and When the rotation shaft 17b of the front stopper gear 17 held between the support grooves 24 is positioned at the corner of the guide groove 35 that is L-shaped as the slide bar 27 moves, the support groove is pressed by the guide groove 35. 24 moves to the center of the slider 12. When the rotating shaft 17b moves in the support groove 24, the rotating shaft 17b is rotated around the pinion gear 15 around the rotating pinion gear 15 and close to the other pinion gear 16 that has been separated. The pinion gear 16 meshes with the pinion gear 16. When the tip of the contact portion 37 of the slide bar 27 that has been in contact with the protruding portion 28c of the rotating member 28 is separated from the protruding portion 28c by pulling back the slide bar 27, the elastic force of the biasing spring 29 is restored. Then, the rotary shaft 18 b of the rear stopper gear 18 is moved along the support groove 25 to the center of the slider 12. At this time, by rotating the stopper gear 18 around the pinion gear 16 around the rotation shaft 16b of the pinion gear 16 meshing with the stopper gear 18, the one pinion gear 15 that has been separated is brought close to the pinion gear 15. The pinion gear 15 is engaged. The stopper gears 17 and 18 are simultaneously meshed with a pair of pinion gears 15 and 16 that rotate relative to each other, whereby the rotation of the pinion gears 15 and 16 is restricted and the slider 12 is stopped at a desired position. Is possible.

  As described above, by providing the switching means 20 for switching the stopper gears 17 and 18 to the state in which the stopper gears 17 and 18 are simultaneously meshed with the pair of pinion gears 15 and 16, the locking position of the slider 12 with respect to the base 11 is desired. Free stop is possible at the position. In other words, when the stopper gears 17 and 18 are engaged with the pair of pinion gears 15 and 16 simultaneously from both sides in the sliding direction, the rotation of the pair of pinion gears 15 and 16 is restricted, and the slider is stopped. it can. On the other hand, by making the stopper gears 17 and 18 not mesh with the pair of pinion gears 15 and 16 at the same time, the pair of pinion gears 15 and 16 can be freely rotated and the slider can be moved. be able to. As a result, the lock position of the slider 12 with respect to the base 11 can be set steplessly.

  Further, since the pair of pinion gears 15 and 16 are in phase relation with each other by the racks 13 and 14 on both sides, the rotation shaft 15b of the pinion gear 15 is kept in a state where the stopper gear 17 is always meshed with one pinion gear 15. And the stopper gear 18 is always meshed with the one pinion gear 16, and the stopper gear 17 is turned to the pinion gear 15 by turning around the rotation shaft 16 b of the pinion gear 16. The stopper gear 18 can mesh with the pinion gear 16 satisfactorily. That is, since the teeth of the stopper gear and the pinion gear are instantaneously engaged with each other without interfering with each other, the stop position of the slider 12 desired by the user can be more accurately reflected.

  Further, since the stopper gears 17 and 18 are simultaneously meshed with the pair of pinion gears 15 and 16 that rotate relative to each other from both sides in the sliding direction, for example, the direction of the external force changes from the forward direction to the backward direction or vice versa. Even if the rotation direction of the pinion gears 15 and 16 is reversed, any one of the pair of stopper gears 17 and 18 always rotates in the biting direction with respect to the pinion gears 15 and 16. The locked state of the slider 12 with respect to the base 11 can be reliably maintained in both the forward direction and the backward direction.

Next, a second embodiment of the present invention will be described below mainly with reference to FIGS.
5 and 6 show a slide lock mechanism 45 according to the second embodiment adapted to the center console 1 described above. The slide lock mechanism 45 of the present embodiment includes a base 11 (see FIG. 2) and a slider 46 supported so as to be slidable with respect to the base 11. A fixed-side rack 47 having a predetermined length corresponding to the slide stroke is fixed.

  The slider 46 includes a slide base 48 fixed to the armrest 5 side, a pinion gear 49 that is rotatably provided on the slide base 48 and meshes with the gear portion 47d of the fixed rack 47, and a gear portion of the fixed rack 47. A movable side rack 50 that is arranged in parallel with the fixed side rack 47 so that its gear part 50b faces the 47d, and is provided so as to be close to and away from the fixed side rack 47 while maintaining parallelism; An urging unit 51 that constantly urges the movable rack 50 toward the fixed rack 47 and a switching unit 52 that switches between a state in which the movable rack 50 is engaged with the pinion gear 49 and a state in which the movable rack 50 is not engaged are configured. Has been.

The movable rack 50 is about half as long as the fixed rack 47, and is always urged toward the fixed rack 47 by the urging means 51 provided on the side 50c opposite to the gear portion 50b. ing. The movable rack 50 is provided with a pair of shafts 53, 53 provided in a vertical posture with respect to the side portion 50 c so as to be spaced from each other, and one end side can slide on the side portion of the slide base 48. The pair of shafts 53 and 53 are covered with a coil-shaped pressing spring 54. The urging means 51 is composed of such a pair of shafts 53, 53 and a pressing spring 54, and makes the movable rack 50 close to and away from the fixed rack 47. As a result, the gear portion 50b of the movable rack 50 can be engaged with the pinion gear 49 that is always engaged with the fixed rack 47. In other words, the movable rack 50 is moved away from the stationary rack 47 while being kept parallel to the fixed rack 47.
Such a movable rack 50 is provided with a columnar engagement protrusion 55 substantially at the center in the longitudinal direction.

  The switching means 52 includes a slide bar 56 connected to the lever 30 and a link member 57 that connects the slide bar 56 and the movable rack 50 and tilts by sliding the slide bar 56 in the sliding direction. Has been.

  The slide bar 56 is a thin plate extending in the sliding direction, is formed longer than the fixed rack 47, and is disposed above the fixed rack 47. One end of the link member 57 is connected to the end opposite to the lever 30.

  The link member 57 has a thin rod shape, and a base shaft 58 provided at one end side slightly from the substantially central portion thereof is rotatably supported by the slide base 48. As described above, the one end side is coupled to the slide bar 56. . A cylindrical projection 60 that can be inserted into a substantially square locking groove 59 formed in the slide base 48 is provided on one end side, and an engagement projection 55 of the movable rack 50 is provided on the other end side. A support groove 61 into which can be inserted is formed. With such a link member 57, the slide bar 56 and the movable rack 50 are substantially connected. The support groove 61 extends in the longitudinal direction of the link member 57, and the engagement protrusion 55 is movable along the extending direction. Further, as shown in FIG. 5, when the movable rack 50 and the fixed rack 47 are close to each other, the engagement protrusion 55 of the movable rack 50 and the engagement protrusion 55 of the slide bar 56 are They are located on the inner sides of the support grooves 61 and are close to each other. In this case, the movable rack 50 urged to the fixed rack 47 by the pressing spring 54 meshes with the pinion gear 49 and restricts the rotation of the pinion gear 49.

Next, the movement of the slide lock mechanism 45 will be described in detail.
When the slider 46 is moved with respect to the base 11, as shown in FIG. 6, when the lever 30 is pulled up and the slide bar 56 is slid forward, one end of the link member 57 is moved forward with the base shaft 58 as a base point. The link member 57 tilts so that the other end moves rearward. As a result, the movable rack 50 is pushed up against the urging force of the push spring 54 while the engaging protrusion 55 of the movable rack 50 is moved outward in the support groove 61. At this time, since the other end side of the pair of shafts 53, 53 is movably provided on the slide base 48, the movable rack 50 can be moved. Accordingly, when the meshing engagement with the movable rack 50 is released and the rotation restriction of the pinion gear 49 is released, the pinion gear 49 can rotate along the fixed rack 47, and the movement of the slider 46 with respect to the base 11 can be performed. It becomes possible. Note that the phase shift amount of the gear of the movable rack 50 when the slider 46 moves in the sliding direction is such that the teeth of the gear portion 50b of the movable rack 50 enter between the teeth of the pinion gear 49 and the meshing is good. The amount is obtained.

  When the slider 46 is stopped with respect to the base 11, the lever 30 is lifted up at a desired position as shown in FIG. Then, the link member 57 is tilted so as to return to the original posture by the elastic return of the push spring 54, and the slide bar 56 moves rearward. At the same time, the movable rack 50 comes close to the fixed rack 47, and the movable rack 50 meshes with the pinion gear 49. Accordingly, since the rotation of the pinion gear 49 is restricted by the fixed rack 47 and the movable rack 50, the slider 46 can be stopped.

  Accordingly, the rotation of the pinion gear 49 is restricted by bringing the movable rack 50 into mesh with the pinion gear 49 that is constantly meshed with the fixed rack 47 by the switching means 52, and the forward and backward directions of the slider 46 are controlled. It is possible to reliably regulate the slide to. In addition, since the pinion gear 49 can be rotated by switching to a state in which it does not mesh, the lock position of the slider 46 that slides relative to the base 11 can be freely stopped to a desired position. Therefore, the lock position of the slider 46 with respect to the base 11 can be set steplessly.

  The movable rack 50 is pivotally supported so that one end side thereof is close to and away from the pinion gear 49 without being translated relative to the fixed rack 47, and the gear portion 50b on one end side is supported. May be configured to mesh with the pinion gear 49. With this configuration, the teeth of the gear portion 50b of the movable rack 50 can be engaged with the pinion gear 49, and the rotation of the pinion gear 49 can be reliably regulated. Further, the gear portion 50b of the movable rack 50 may be composed of, for example, only one tooth, and in that case, the pinion gear 49 can be obtained by engaging the gear portion 50b composed of one tooth with the pinion gear 49. Can be controlled.

The other end of the coil spring 74 provided in the first frame 67 is locked to a locking shaft portion 78 provided in the front center portion of the slide base 65, while the other end of the coil spring provided in the second frame 69 is a slide. The coil springs 74 and 75 are attached so as to be expandable and contractable by being engaged with an engagement shaft portion 79 provided at the rear center portion of the base 65. Thus, the first frame 67 and the second frame 69 are provided so as to be close to and separated from each other along the sliding direction. In addition, the first frame 67 is provided with a columnar protrusion 80 that protrudes vertically upward from approximately the center of the surface. On the other hand, the second frame 69 is provided with a columnar locking projection 81 that projects vertically upward from the center of the surface and has a larger diameter than the projection 80.

  The first frame 67 includes first wedge arms 66 on both sides thereof, and the second frame 69 includes second wedge arms 68 on both sides thereof. Each of the first wedge arm 66 and the second wedge arm 68 has an elongated rod shape with both ends formed in a semicircular shape. From the upper surface of the first wedge arm 66 and the second wedge arm 68 to one end side thereof. A cylindrical first protrusion 72 that protrudes vertically upward is provided, and a second protrusion 73 having a similar shape is also provided at the center in the longitudinal direction. The first wedge arm 66 and the second wedge arm 68 can swing around the second protrusion 73 as a base point. The first wedge arm 66 contacts or separates from the guide rail 70 by moving relatively along the side of the first frame 67 in synchronization with the movement of the first frame 67 in the sliding direction. The second wedge arm 68 contacts or separates from the guide rail 70 by moving relatively along the side of the second frame 69 in synchronization with the movement of the second frame 69 in the sliding direction. Here, the length of the first wedge arm 66 is longer than the distance from the side portion 67d of the first piece 67 to the guide rail 70, and the length of the second wedge arm 68 is also on the second piece 69 side. The distance from the portion 69d to the guide rail 70 is longer.

  The slide base 65 has a substantially rectangular first support groove 82 for inserting and holding the first protrusions 72 of the first wedge arm 66 and the second wedge arm 68, and the first wedge arm 66 and the second wedge arm 68. An oval second support groove 83 for inserting and holding the second protrusion 73 is formed. The length of the first support groove 82 in the sliding direction is set based on the movement range of the first frame 67 and the second frame 69 that are in contact with and away from each other, and the width direction length is determined by the movement of the first frame 67 or the second frame 69. The moving range of the first wedge arm 66 or the second wedge arm 68 is set in consideration.

  The second support groove 83 extends along the width direction of the slide base 65 and is located at the approximate center of the length of the first support groove 82 in the slide direction. The first wedge arm 66 and the second wedge arm 68 are provided. The first wedge arm 66 or the second wedge arm 68 is allowed to move along with the movement of the first piece 67 or the second piece 69 while rotating the first piece 67 and the second wedge arm 68. regulate. Such a second support groove 83 positions the first wedge arm 66 and the second wedge arm 68 with respect to the slide base 65.

  The switching means 71 includes a slide bar 84 having one end connected to the lever 30 and the other end inserted into the slide base 65, and a link member 85 that transmits the movement of the slide bar 84 to the first frame 67. ing. The slide bar 84 has a length in the slide direction, and is provided so as to be slightly biased toward the one guide rail 70 side from the center. Here, the slide bar 84 is connected to a link mechanism including the lever 30 as shown in FIG. 2, but in this embodiment, unlike the configuration shown in FIG. 2, the slide bar 84 slides when the lever 30 is pulled up. The bar 84 slides backward, and when it is pulled down, the slide bar 84 slides forward. Further, a first contact portion 86 that protrudes toward the second piece 69 side is provided on one side, and the first contact portion 86 is formed between the shaft portion 77 of the second piece 69 and the locking projection portion 81. The first abutting portion 86 is formed so as to abut on the locking projection 81 of the second frame 69 when the slide bar 84 is inserted forward. Further, on the other side of the predetermined portion located on the inner side in the longitudinal direction from the first contact portion 86, a second contact portion 87 that protrudes toward one guide rail 70 and extends toward the lever 30 is provided. The second contact portion 87 is in contact with the link member 85 when the slide bar 84 slides forward.

  The link member 85 has a central base shaft 85b supported rotatably on the slide base 65, and a locking groove 88 extending in the longitudinal direction of the link member 85 is formed on one end side. The projection 80 of the first frame 67 is inserted into the locking groove 88, and the link member 85 is inclined rearward by locking the projection 80 to the proximal end side of the locking groove 88. Held in.

  As described above, the first wedge arm 66 and the second wedge arm 68 are brought into contact with the guide rail 70 at a predetermined inclination angle. It is not perpendicular or parallel to the length direction (slide direction), and therefore there is a preferred angle range as will be described later, but in principle it is 0 for the length direction (slide direction) of the guide rail 70. It refers to a state that exceeds degrees (ie, parallel state) and is less than 90 degrees (ie, vertical state).

Next, the movement of the slide lock mechanism 63 will be described in detail.
FIG. 7 shows a slide lock mechanism 63 in which the armrest 5 is in a used (locked) state, and the slider 64 is locked to the base 11. At this time, the lever 30 is held in a lowered state, and the slide bar 84 is held in a state of sliding relatively forward. In the locked slider 64, the first frame 67 and the second frame 69 are in close proximity to each other via the slide bar 84 and the link member 85, and the first wedge arm 66 and the second wedge arm 68 provided on each of the first frame 67 and the second frame 69 are provided. It is in contact with the guide rail 70.

  When trying to move the slider 64 thus locked, the lever 30 is pulled up. Then, as shown in FIG. 8, the slide bar 84 is retracted in the sliding direction, and the first spring 67 is slid forward and the second frame 69 is slid backward as the coil springs 74 and 75 are elastically restored. Then, the link member 85 tilts so that the protrusion 80 of the first frame 67 is locked outward in the longitudinal direction of the locking groove 88. As a result, the second contact portion 87 of the slide bar 84 that has been in contact with one end of the link member 85 is separated. Further, when the first piece 67 moves forward, the first wedge arms 66 on both sides move so as to fall from the side portion 67d of the first piece 67 to the tapered portion 67b side, and the first wedge arm 66 moves to the guide rail. The contact state is released by separating from 70. At this time, the first wedge arm 66 is held in a posture in which the second protrusion 73 is engaged with the end of the second support groove 83 of the slide base 65. On the other hand, when the second piece 69 moves backward, the second wedge arms 68 on both sides move so as to fall from the side portion 69d of the second piece 69 toward the tapered portion 69b, and the second wedge arm 68 moves to the guide rail 70. The contact state is released by separating from. At this time, the second wedge arm 68 is held in a posture in which the second protrusion 73 is engaged with the end of the second support groove 83 of the slide base 65.

  In this manner, the pair of first wedge arms 66 and the pair of second wedge arms 68 are moved away from the guide rail 70 by moving the slider 64 inward, and the slider 64 moves in the forward and backward directions. The restriction, that is, the locked state can be released.

  When the slider 64 is moved to stop at a desired position, the lever 30 is pulled down. Then, as shown in FIG. 7, the slide bar 84 moves forward, the first contact portion 86 of the slide base 65 contacts the locking projection 81 of the second top 69, and resists the biasing force of the coil spring 75. Slide the second frame 69 forward. Then, the second wedge arms 68 on both sides falling to the tapered portion 69b side of the second frame 69 rotate backward with the second protrusion 73 engaged with the second support groove 83 as a base point. The second frame 69 moves to the guide rail 70 side along the tapered portion 69b, the one end side of the second wedge arm 68 is guided on the side portion 69d, and the other end side contacts the guide rail 70. At this time, since the second wedge arm 68 is formed to have a length longer than the distance from the side portion 69d of the second top 69 to the guide rail 70, a predetermined inclination angle with respect to the guide rail 70 is obtained. (For example, about 5 ° to 10 °). In this way, the pair of second wedge arms 68 provided on the second frame 69 abuts on the guide rail 70 at a predetermined inclination angle and is held in a posture inclined rearward, so that the guide rail 70 in particular is When a force in a direction of moving forward relative to the second wedge arm 68 is exerted, a wedge action due to biting into the guide rail 70 is exhibited.

  In synchronization with this, the second abutting portion 87 of the slide bar 84 abuts on one end of the link member 85 to tilt the link member 85 forward. At this time, the link member 85 tilts while moving the protrusion 80 of the first top 67 inserted into the locking groove 88 inward in the longitudinal direction of the locking groove 88. When the first piece 67 slides backward against the biasing force of the coil spring 74 by tilting the link member 85, the first wedge arms 66 on both sides are engaged with the second support groove 83. It moves to the guide rail 70 side along the taper portion 67b of the first frame 67 while tilting forward with reference to 73. Thus, one end side of the first wedge arm 66 is guided on the side portion 67d and the other end side comes into contact with the guide rail 70. At this time, since the first wedge arm 66 is formed to have a length longer than the distance from the side portion 67d of the first top 67 to the guide rail 70, a predetermined inclination angle with respect to the guide rail 70 is obtained. (For example, about 5 ° to 10 °). As described above, the pair of first wedge arms 66 provided on the first top 67 abut against the guide rail 70 at a predetermined inclination angle, and are held in a posture inclined forward. When a force in the direction of retreating relative to the first wedge arm 66 is exerted, a wedge action due to biting into the guide rail 70 is exhibited.

  As described above, the first wedge arm 66 and the second wedge arm 68 are inclined in the opposite directions in the sliding direction and brought into contact with the guide rail 70, so that the slider is operated by the wedge action of the first wedge arm 66. 64 is restricted, and the wedge action of the second wedge arm 68 restricts the backward movement of the slider. Thereby, the slider 64 is reliably locked.

  That is, by bringing the first wedge arm 66 and the second wedge arm 68 into contact with the guide rail 70 at a predetermined inclination angle, the pair of first wedge arms 66 and the pair of second wedge arms 68 with respect to the guide rail 70 are respectively provided. As a result, the wedge action can be obtained from the bite, and the slider 64 can be surely stopped. That is, when the first wedge arm 66 and the second wedge arm 68 are in perpendicular contact with the guide rail 70, the wedge effect is not sufficiently obtained, and an excessive external force is applied to the slider 64 in the locked state. In this case, the slider 64 may be accompanied in the direction of the applied external force. However, in the present embodiment, since the first wedge arm 66 and the second wedge arm 68 are brought into contact with the guide rail 70 at a predetermined inclination angle as described above, such a fear is avoided and The locked state of the slider 64 can be reliably maintained in both the forward direction and the backward direction. Further, the slider 64 can be moved by releasing the wedge action by separating the pair of first wedge arms 66 and the pair of second wedge arms 68 from the guide rail 70, so that the slider 64 is positioned with respect to the base 11. Thus, the lock position of the slider 64 can be set steplessly.

  Furthermore, the first wedge arm 66 and the second wedge arm 68 are inclined in directions opposite to each other in the sliding direction and brought into contact with the guide rail 70, whereby the slider 64 advances by the wedge action obtained from the first wedge arm 66. The wedge 64 obtained from the second wedge arm 68 can regulate the backward movement of the slider 64. Thereby, the locking force can be exerted in the forward direction and the backward direction of the slider 64, and the slider 64 can be surely stopped.

Next, a fourth embodiment of the present invention will be described below mainly with reference to FIGS.

  The first link member 91 is configured such that a base shaft 91 b provided at the center in the longitudinal direction is rotatably supported at the center of the slide base 96, and is inserted into the third support groove 97 of the slide base 96 at one end thereof. Possible protrusions 99 are formed. The first link member 91 swings as the protrusion 99 slides in the third support groove 97. As shown in FIG. 9, the first link member 91 is held in a state in which the protrusion 99 is locked to the base of the third support groove 97 and the second piece 69 is pressed backward in the sliding direction at the other end. .

  The second link member 92 is such that a central base shaft 92b is rotatably supported at a predetermined position of the slide base 96, and a guide groove 100 extending in the longitudinal direction of the second link member 92 is formed at one end. Has been. A projection 95 of the first frame 67 is inserted into the guide groove 100, and the other end of the second link member 92 is inclined forward by engaging the projection 95 with the proximal end of the guide groove 100. Held in.

  The slide bar 98 has a length in the sliding direction, and is provided so as to be slightly biased toward the one guide rail 70 side from the center of the slide base 96. A first abutting portion 101 that protrudes toward one guide rail 70 and extends rearward is formed on one side, and can abut on one end of the second link member 92. Yes. In addition, a pair of second contact portions 102 projecting toward the first piece 67 are formed on the other side at a predetermined interval, and the first piece 67 is locked between the second contact portions 102. The protrusion 94 is positioned, and when the slide bar 98 is slid in the sliding direction, one of the second contact portions 102 can contact the locking protrusion 94 of the first frame 67. ing. One end of the above-described first link member 91 is connected to the slide bar 98, and the first link member 91 is swung as the slide bar 98 slides.

  The first frame 67 and the second frame 69 are notched on the end surfaces of the first frame 67 or the second frame 69 facing each other, so that the tip of the slide bar 98 is directly on the second frame 69. While the contact can be avoided, the end of the first link member 91 can be prevented from contacting the first frame 67.

Next, the movement of the slide lock mechanism 90 will be described in detail.
FIG. 9 shows a slide lock mechanism 90 in which the armrest 5 is in a use (locked) state, and the slider 93 is locked to the base 11. At this time, the lever 30 is held in a lowered state, and the slide bar 84 is held in a state of sliding relatively forward. In the locked slider 93, the first frame 67 and the second frame 69 are separated from each other via the slide bar 98 and the first link member 91 linked to the slide bar 98, and the first wedges provided in the first frame 67 and the second frame 69, respectively. The arm 66 and the second wedge arm 68 are in contact with the guide rail 70.

  When the slider 64 thus locked is to be moved, the lever 30 is pulled up. Then, as shown in FIG. 10, the slide bar 98 slides backward, and the second contact portion 102 on the front side of the slide bar 98 comes into contact with the locking projection portion 94 of the first piece 67 and the first piece. 67 is moved backward. In conjunction with this, the first wedge arms 66 on both sides move so as to fall from the side portion 67c of the first top 67 toward the tapered portion 69b, and the first wedge arms 66 are separated from the guide rail 70. Thereby, the contact state with respect to the guide rail 70 of the 1st wedge arm 66 is cancelled | released. The first wedge arm 66 is held in a posture in which the second protrusion 73 is engaged with the end of the second support groove 83 of the slide base 65.

  Further, as the slide bar 98 slides, the first link member 91 slides while the protrusion 99 of the first link member 91 connected to the slide bar 98 moves in the third support groove 97 of the slide base 96. The posture is substantially perpendicular to the direction. Thereby, the contact state of the first link member 91 with respect to the second frame 69 is released. Then, the first abutting portion 101 of the slide bar 98 abuts on one end of the second link member 92 and further tilts while pressing the second link member 92, so that the second frame 69 in the guide groove 100 is tilted. The second frame 69 is moved forward while changing the position of the protrusion 95. In conjunction with this, the second wedge arms 68 on both sides move so as to fall from the side portions 69c of the second top 69 to the tapered portion 69b side, and the second wedge arms 68 are separated from the guide rails 70. Thereby, the contact state of the second wedge arm 68 with respect to the guide rail 70 is released. The second wedge arm 68 is held in a posture in which the second protrusion 73 is engaged with the end of the second support groove 83 of the slide base 65.

  When the slider 93 is moved to stop at a desired position, the lever 30 is pulled down. Then, as shown in FIG. 9, the slide bar 98 slides forward, the rear second contact portion 102 comes into contact with the locking projection 94 of the first piece 67, and the first piece 67 moves forward. Slide. Then, the first wedge arms 66 on both sides that have fallen to the taper portion 67b side of the first frame 67 rotate backward with the second protrusion 73 that engages with the second support groove 83 as a base point. By moving relatively toward the guide rail 70 side along the tapered portion 67 b of the two frames 67, one end side of the first wedge arm 66 is guided on the side portion 66 c and the other end side abuts on the guide rail 70. At this time, since the first wedge arm 66 is formed to have a length longer than the distance from the side portion 67d of the first top 67 to the guide rail 70, a predetermined angle (with respect to the guide rail 70) For example, the contact is made at about 5 ° to 10 °.

  Further, as the slide bar 98 slides forward, the other end of the first link member 91 connected to the slide bar 98 is pulled forward, and the protrusion 99 moves along the third support groove 97. However, when the first link member 91 tilts, the one end side presses the second frame 69. As a result, the second frame 69 is moved rearward, and the second wedge arm 68 rotates forward with the second protrusion 73 engaged with the second support groove 83 as a base point. By moving relatively toward the guide rail 70 side along the taper portion 69 b of the 69, one end side of the second wedge arm 68 is guided on the side portion 69 c and the other end side contacts the guide rail 70. Since the second wedge arm 68 has a length longer than the distance from the side portion 69d of the second top 69 to the guide rail 70, the second wedge arm 68 has a predetermined angle with respect to the guide rail 70 (for example, The contact is made at about 5 ° to 10 °.

  As described above, the first wedge arm 66 and the second wedge arm 68 abut against the guide rail 70 at an angle opposed to each other in the sliding direction, so that the backward movement of the slider 93 is restricted by the wedge action of the first wedge arm 66. The forward movement of the slider 93 is restricted by the wedge action of the second wedge arm 68. Therefore, the slider 93 can be locked by pulling up the lever 30. From the above, it is possible to achieve the same effect as that of the third embodiment.

  In addition, the contact angle range of the first wedge arm 66 and the second wedge arm 68 with respect to the guide rail 70 is not limited to the above, but is appropriately set depending on the dimension setting of a component, a desired wedge action, and the like. In other words, any angle may be used as long as it can exert a wedge action capable of reliably locking the sliders 64 and 93.

The other end 115 b of the close coil spring 115 protrudes in the radial direction of the close coil spring 115 and is locked in the locking groove 117 b of the cylindrical member 117.

  The cylindrical member 117 is rotatably supported by the base portion 113, is disposed so as to surround the contact coil spring 115 from the radial direction, and is rotatable about the axis O with respect to the base portion 113. . A locking groove 117b for locking the other end 115b of the contact coil spring 115 is formed on the rotating portion 114 side of the cylindrical member 117, and a torque release boss 110 is formed on the outer peripheral surface. When the torque release boss 110 is pressed in the circumferential direction and the cylindrical member 117 is rotated in the R direction in the figure, the other end 115b is also rotated in the R direction, and the contact coil spring 115 is expanded in diameter.

  The gear portion B is engaged with the one-way clutch main body A to constitute the one-way clutch C1, and has a substantially disk shape in which teeth are formed in the entire outer peripheral portion, and the outer peripheral portion is provided on the base 11 side. The gear 104b of the rack 104 is engaged.

  The other one-way clutch C2 has substantially the same configuration as the one-way clutch C1 described above, and includes a left-handed close-contact coil spring 116 wound in the L direction in FIG. The torque release boss 111 of the one-way clutch C2 has a shorter length than the torque release boss 110 of the one-way clutch C1.

  These one-way clutches C1 and C2 are provided on the slide base 107 in a state in which the upper surfaces of the gear portions B are abutted with each other and the shaft centers are aligned to fix both gear portions B in the same phase. At this time, the shaft centers of the one-way clutches C1 and C2 are arranged in the center of the slide base 107 so as to be orthogonal to the slide direction, and the support shafts 122 are fixed to the side portions of the slide base 107. The torque release bosses 110 and 111 of the one-way clutches C1 and C2 are coaxially matched.

  The switching means 112 has one end coupled to the lever 30 and the other end parallel to the first slide bar 127 via the rack 104 and the first slide bar 127 engaged with the torque release boss 110 of the one-way clutch C1. And a link member 129 that connects the first slide bar 127 and the second slide bar 128 to each other. The second slide bar 128 contacts one end with the torque release boss 111 of the other one-way clutch C2. . The first slide bar 127 and the second slide bar 128 are disposed on both sides of the slide base 107 in the width direction, and the second slide bar 128 is formed to have a length shorter than that of the first slide bar 127. Yes.

  In the first slide bar 127, a first groove portion 130 into which the torque release boss 110 of the one-way clutch C1 can be inserted is formed along the slide direction on the other end side. Furthermore, a cylindrical first protrusion 131 protruding vertically from the surface is provided at a predetermined position located on the inner side in the longitudinal direction from the first groove 130.

  The second slide bar 128 has an end that is perpendicular to the longitudinal direction and abuts against the torque release boss 111 of the other one-way clutch C2. Further, a columnar second protrusion 132 protruding vertically from the surface is provided on the other end side.

  The slide base 107 is formed with a second groove part 133 into which the torque releasing boss 111 of the other one-way clutch C2 can be inserted. The second groove part 133 and the first groove part 130 are located in the longitudinal center of the slide base 107. Are formed to extend in opposite directions along the sliding direction. Then, the torque release bosses 110 and 111 of the one-way clutches C1 and C2 are inserted into the first groove 130 and the second groove 133 so that their positions coincide with each other at the center of the slide base 107, as shown in FIG. Is done.

  The link member 129 is a thin rod-shaped member having a length that allows the first slide bar and the second slide bar to be connected to each other, and a base shaft 129b provided at a substantially central part thereof can tilt to the slide base 107. It is supported by. A pair of rectangular support grooves 134 are formed at both ends of the link member 129. When the first protrusion 131 and the second protrusion 132 formed on the first slide bar 127 and the second slide bar 128 are respectively inserted into the support grooves 134, the link member 129 is as shown in FIG. It is provided with a simple inclination posture. As a result, the first slide bar 127 and the second slide bar 128 are substantially connected to each other via the link member 129. When the first slide bar 127 is slid in the slide direction, the link member 129 tilts with the base shaft 129b as the base point, and the second slide bar 128 slides in the direction opposite to the slide direction of the first slide bar 127. . When the link member 129 tilts, the link member 129 tilts while changing the positions of the first protrusion 131 and the second protrusion 132 in the support groove 134.

Next, the movement of the slide lock mechanism 105 will be described in detail.
When the slider 106 is to be slid with respect to the base 11, when the lever 30 is pulled up and the first slide bar 127 is slid forward, it engages with one end of the first groove 130 of the first slide bar 127. When the torque release boss 110 tilted forward in the sliding direction, the one-way clutch main body A (base portion) of the one-way clutch C1 rotates so as to increase the diameter of the contact coil spring 115. Further, by sliding the first slide bar 127 forward, the link member 129 tilts in the direction of the arrow in the figure, and slides the second slide bar 128 backward. Accordingly, the end of the second slide bar 128 tilts the torque release boss 111 engaged with the second groove 133 of the slide base 107 to the rear side, whereby the one-way clutch main body (base portion) of the one-way clutch C2. ) A rotates so that the contact coil spring 116 expands in diameter. Then, in each one-way clutch C1, C2, a gap is formed between the contact coil springs 115, 116 and the base portion 113 and the rotating portion 114, whereby the rotating portion 114 rotates in the sliding direction with respect to the base portion 113. Is allowed to idle, so that the rotational driving force (power) is not transmitted from the gear portion B to the base portion 113. Therefore, the gear portion B of each one-way clutch C1, C2 is rotatable with respect to the gear portion 104b of the rack 104, and the slider 106 is slidable in the sliding direction.

  On the other hand, when the slider 106 is to be stopped at a desired position with respect to the base 11, when the lever 30 is released, the one-way clutch is released by the elastic return accompanying the contraction of the contact coil springs 115, 116 whose diameter has been expanded. The main body (base portion) A rotates and returns to the original position so that the torque release bosses 110 and 111 of the one-way clutches C1 and C2 coincide with each other in the coaxial direction. At the same time, the link member 129 tilts as shown by the arrow in the figure, the second slide bar 128 slides forward, and the first slide bar 127 slides backward. As described above, when the coil springs 115 and 116 are reduced in diameter, the base portion 113 and the gear portion B of each one-way clutch C1 and C2 are integrated, so that the gear portion B rotates (rotates) relative to the base portion 113. Therefore, the slider 106 is locked without idling.

  Accordingly, the slider 106 is provided with a pair of one-way clutches C1 and C2 having coil springs 115 and 116 whose winding directions are opposite to each other so that the rotation restricting directions are opposite to each other in the sliding direction. The sliding in both directions is restricted, and the slider 106 can be surely stopped. That is, the backward movement of the slider 106 is restricted by the one-way clutch C1, and the forward movement of the slider 106 is restricted by the one-way clutch C2. Accordingly, since the locking force can be exerted in the forward direction and the backward direction of the slider 106, the slider 106 can be surely stopped. In addition, the first slide bar 127 and the second slide bar 128 press the torque release bosses 110 and 111 of the one-way clutches C1 and C2 to increase the diameters of the coil springs 115 and 116, and rotate the gear portion B to the one-way clutch body A. Is prevented from being transmitted, the gear portion B can be idled and the slider 106 can be slid in both directions. Therefore, the lock position of the slider 106 with respect to the base 11 can be set steplessly. In addition, by providing the torque release bosses 110 and 111 in the one-way clutches C1 and C2, the transmission of the rotational driving force can be easily released, and the release operation can be performed reliably.

Next, a sixth embodiment of the present invention will be described below mainly based on FIGS. 14 and 15 with reference to FIG.
FIGS. 14 and 15 show a slide lock mechanism 136 of the sixth embodiment adapted to the center console 1. The difference from the fifth embodiment is that the base 11 (see FIG. 2) has a pair of racks 13, 14 is a point in which the pair of one-way clutches C1 and C2 are provided on the slider 137 so that the gear portions 13b and 14b are opposed to each other, and are individually engaged with the gear portions 13b and 14b. Note that description of the same configuration as that of the fifth embodiment is omitted.

  The slider 137 of the slide lock mechanism 136 of this embodiment includes a slide base 138 attached to the bottom of the armrest 5 (see FIG. 1) and a gear portion B that individually meshes with the gear portions 13b and 14b of the pair of racks 13 and 14.

  The one-way clutches C1 and C2 are provided with one-way clutches C1 and C2 having substantially the same configuration as the one-way clutches C1 and C2 described above. One one-way clutch C1 includes a right-handed close-contact coil spring 115 and the other one-way clutch C1 and C2. The clutch C2 includes a left-handed close-contact coil spring 116. Then, the torque releasing bosses 110 and 111 are opposed to each other, and the gear portion 13b of the one rack 14 is engaged with the gear portion 13b of the other rack 13 so that the gear portion B of the one-way clutch C1 (right-handed) meshes with the gear portion 14b of one rack 14. The support shafts 122 of the one-way clutches C1 and C2 are attached to the slide base 138 so that the gear portion B of the clutch C2 (left-handed) is engaged. The lengths of the torque release bosses 110 and 111 of the one-way clutches C1 and C2 used here may be the same length.

  The switching means 139 has a first slide bar 140 whose one end is connected to the lever 30 and whose other end can abut against the torque release boss 110 of one one-way clutch C1, and is arranged in parallel with the first slide bar 140. One end side is configured by a second slide bar 141 that can abut on the torque release boss 111 of the other one-way clutch C2, and a link member 142 that connects the first slide bar 140 and the second slide bar 141 to each other. The first slide bar 140 and the second slide bar 141 are arranged along the slide direction and are parallel to each other.

  The first slide bar 140 has a length in the sliding direction, and has a contact portion 143 protruding toward the rack 14 on one side at the other end side, and the corresponding contact portion 143 is the one-way clutch C1. The torque release boss 110 is in contact with the other. Furthermore, a cylindrical first protrusion 144 protruding vertically from the surface is provided at a predetermined position located on the inner side in the longitudinal direction from the contact portion 143.

  The second slide bar 141 has a substantially rectangular shape, and is provided with a contact portion 145 extending backward from one side along the slide direction. The corresponding contact portion 145 is a torque release boss 111 of the one-way clutch C2. It comes to contact with. A cylindrical second protrusion 146 that protrudes perpendicularly from the surface of the second slide bar 141 is provided at the approximate center.

  The link member 142 is a thin rod-like member formed to have a length that allows the first slide bar 140 and the second slide bar 141 to be connected to each other, and a base shaft 142b provided at a substantially central portion thereof is attached to the slide base 138. It is supported so that it can tilt. The link member 142 is formed with a pair of rectangular support grooves 147 into which the first protrusion 144 and the second protrusion 146 of the first slide bar 140 and the second slide bar 141 can be individually inserted. . When the first projecting portion 144 and the second projecting portion 146 are inserted so as to be engaged with the outer sides in the support grooves 147, the link member 142 is perpendicular to the sliding direction as shown in FIG. It is provided with a proper posture. The first slide bar 140 and the second slide bar 141 are substantially connected through such a link member 142. Further, when the first slide bar 140 is slid in the slide direction, the link member 142 tilts with the base shaft 142b as a base point, and slides the second slide bar 141 in a direction opposite to the slide direction of the first slide bar 140. When the link member 142 tilts, the link member 142 tilts while changing the positions of the first protrusion 144 and the second protrusion 146 in the support groove 147.

Next, the movement of the slide lock mechanism 136 will be described in detail.
When trying to slide the slider 137 with respect to the base 11, when the lever 30 is pulled up and the first slide bar 140 is slid forward as shown in FIG. 15, the torque release boss 110 of the one-way clutch C1 is moved to the torque release boss 110. The abutting contact portion 143 presses the torque release boss 111 to rotate the one-way clutch body (base portion 113) A forward, thereby expanding the diameter of the contact coil spring 115. Further, by sliding the first slide bar 140 forward, the link member 142 is tilted in the direction of the arrow in the drawing, and the other second slide bar 141 is slid backward. Then, the contact portion 145 of the second slide bar 141 rotates so that the torque release boss 111 is pressed rearward and the base portion 113 of the one-way clutch C2 expands the diameter of the contact coil spring 116. Then, in each one-way clutch C1, C2, a gap is formed between each close coil spring 115, 116 and the base portion 113 and the rotating portion 114, whereby the rotating portion 114 moves in the sliding direction with respect to the base portion 113. Is allowed to rotate and idle, so that the rotational driving force (power) is not transmitted from the gear portion B to the base portion 113. That is, the gear portion B of each one-way clutch C1, C2 is rotatable with respect to the gear portions 13b, 14b of the racks 13, 14, and the slider 137 is slidable in the sliding direction.

  On the other hand, when the slider 137 is to be stopped at a desired position with respect to the base 11, when the lever 30 is lifted, the diameters of the contact coil springs 115 and 116 whose diameters have been increased are reduced as shown in FIG. With the accompanying elastic return, the base portion 113 rotates backward, and the torque release bosses 110 and 111 of the one-way clutches C1 and C2 return to their original positions. At the same time, the link member 142 is tilted as shown by the arrows in the figure to slide the second slide bar 141 forward, and the first slide bar 140 slides backward. As described above, when the diameter of the coil spring is reduced, the base portion 113 and the gear portion B are integrated, so that the relative rotation (rotation) of the gear portion B with respect to the base portion 113 is restricted, and the gear portion B does not idle. Therefore, the slider 137 is locked.

  In this way, the slider 106 can be locked by the one-way clutches C1 and C2 whose rotation restricting directions are different from each other in the sliding direction. That is, since the backward movement of the slider 106 is restricted by the one-way clutch C1, and the forward movement of the slider 106 is restricted by the one-way clutch C2, a locking force can be exerted in the forward and backward directions of the slider 106. The slider 106 can be surely stopped.

  According to the embodiment described above, the armrest 5 can be freely stopped at a position desired by the user. Therefore, it is possible to sufficiently secure an appropriate position of the armrest 5 suitable for the user.

  The one-way clutches C1 and C2 are not limited to the above-described embodiments, and include an outer race that accommodates a plurality of ratchets in a swingable manner and an inner race that is provided with claws that are latched to the ratchet on the outer periphery at equal intervals. The one-way clutch (Japanese Patent Laid-Open No. 2002-054659) that is always urged in the direction in which the ratchet is raised to engage the claw, or the claw portion that protrudes radially inward at a predetermined pitch in the circumferential direction A plate-like elastically deforming portion that is curved in an arcuate shape toward the outer radial direction, and a clutch inner that is provided with a locking projection at the same pitch as the claw portion of the clutch outer. A one-way clutch that can be locked to the claw portion by providing a metal connecting member having an equal interval on the outer peripheral surface of the clutch inner (Japanese Patent Laid-Open No. 2000-1707) No. 8), a first clutch element portion having a tapered portion and a steep stepped portion on the inner peripheral surface of the outer ring, and an outer peripheral surface portion and an outer ring forming a wedge-shaped space portion located on the inner ring at the tapered portion of the outer ring. And a second clutch element part in which a part of the peripheral surface protrudes radially inward and outward, and a needle roller is formed by a spring member. One-way clutch (Japanese Patent Laid-Open No. 09-144777) that prevents axial misalignment by pushing outward in the direction, and a rolling element that has a wedge action between the drive shaft and driven shaft is constrained without a cage It is also possible to use a one-way clutch (Japanese Patent Laid-Open No. 07-103260) or the like in which the driving torque can be stopped by a rolling element having a wedge action with load torque from the driven shaft side.
