摘要： A vehicle seat reclining device includes a ratchet and a guide assembled to be rotatable, a plurality of pawls that are supported by a pair of guide walls provided on the guide, mesh with the ratchet, and are arranged in the relative rotation direction and restrict relative rotation between the ratchet and the guide, and a cam that moves the pawls outward. One of the pawls is a main pawl having a rattle preventing structure. The main pawl includes a bulging portion configured to abut against the pressing portion. Each of the pawls other than the main pawl do not have a bulging portion corresponding to the bulging portion of the main pawl.

摘要： A locking mechanism includes a housing, a cam disposed within the housing, and a plurality of pawls disposed within the housing. The housing includes a first plate and a second plate. The second plate includes a peripheral lip having an interior face that defines a plurality of teeth. Each of the plurality of pawls defines a central axis. Each of the plurality of pawls includes a plurality of pawl teeth. The plurality of pawl teeth include a first middle tooth positioned on a first side of the central axis and a second middle tooth positioned on an opposing second side of the central axis. The first middle tooth has a first flat face facing the central axis and a first curved face facing away from the central axis. The second middle tooth has a second flat face facing the central axis and a second curved face facing away from the central axis.

摘要： A recliner mechanism for a vehicle seat may include a guide plate, a locking plate, a pawl, an actuator hub, and a coil spring. The guide plate includes a recess and a projection. The locking plate includes a surface having teeth formed thereon. The pawl is movable in the recess between a secure position in which the pawl is engaged with the teeth of the locking plate to restrict relative rotation between the guide plate and the locking plate and a release position in which the pawl is disengaged from the teeth of the locking plate to allow relative rotation between the guide plate and the locking plate. Rotation of the actuator hub causes corresponding movement of the pawl between the secure position and the release position. The coil spring includes a first end engaging the actuator hub and a second end that hooks the projection of the guide plate.

摘要： A drive bush configured to circumferentially rotate and drive a pair of wedge members in an eccentric space includes a cylindrical portion rotatably supported inside a boss portion of an internal tooth constituting member, a flange portion integrally formed at a first end portion in the axial direction of the cylindrical portion so as to face one side surface side of the wedge members, and a pushing portion integrally provided on the outer peripheral side of the flange portion, and configured to release a wedge effect by circumferentially pushing the wedge members. The inner surface of the cylindrical portion is integrally formed with a wall portion, and the wall portion is formed with, in the middle thereof, a female spline teeth meshing with the output shaft of a motor. The cylindrical portion, the wall portion including the female spline teeth and the flange portion have substantially the same thickness.

摘要： In the present invention, a gap 73 is formed between an axial-direction outer end portion of an internal gear 30 and an attachment ring 70, and the gap 73 is filled with a lubricant 74. This configuration makes the rotation of the internal gear 30 relative to the attachment ring 70 smoother and also can reduce the generation of abnormal sound. Further, the thickness of second lock plates 60B, 60D between which and an inner surface of a guide bracket 20 rolling balls 65 are not interposed is equal to or more than the distance between the inner surface of the guide bracket 20 and outer surfaces of first lock plates 60A, 60C, between which the rolling balls 65 are interposed, and preferably substantially equal to the distance. This reduces the precession of the first lock plates 60A, 60C and makes it possible for a load input in an axial direction to be mainly received by the second lock plates 60B, 60D.
