Abstract:
1. A reclining adjuster supporting a movable bracket mounted to a seat back frame, rotatable in relation to a stationary bracket, that adjusts an angle of inclination of a seat back, comprising: a worm supported on one of either the stationary bracket or the movable bracket; and a worm wheel that meshes with the worm, supported on the other of either the stationary bracket or the movable bracket; wherein one end in a axial direction of the worm is supported by a fixed bearing mounted on the stationary bracket or the movable bracket, and the other end in the axial direction is supported by a movable bearing which is supported movably in a direction perpendicular to the axial direction of the worm and mounted on the stationary bracket or the movable bracket; further comprising a pressing member movably mounted with respect to the stationary bracket that presses the movable bearing in a direction to approach the worm wheel, to incline the axial center of the worm around an end of a fixed bearing side thereby pressing the worm toward the worm wheel to brake the rotating speed of the worm through frictional force when holding the seat back at predetermined angle of inclination; and a engaging member movably mounted with respect to the stationary bracket that engages the worm and locks the worm to make it impossible to rotate, after the rotating speed is reduced by the pressing member.
