    • PROBLEM TO BE SOLVED: To provide a reclining adjuster which can effectively reduce the backlash between a worm and a worm wheel with a simple structure.
      SOLUTION: A reclining adjuster 10 is for controlling the inclination angle of an upper bracket 14 fixed to a seat back against a lower bracket 12 fixed to a seat cushion around a boss 16. The reclining adjuster has a worm wheel 20 fixed to an upper bracket 14 allowing their united rotation with a common axis, a worm 22 meshed with the worm wheel 20 and a front bearing 30 and a rear bearing 32 which pivot the worm 22 so that the worm 22 can rotate around the lower bracket 12. A bearing member 30B constituting the front bearing 30 is supported so that it can slide vertically along the lower bracket 12. The bearing member 30B is in the upside position (near the worm wheel 20) by the urging force of a flat spring 40 when the inclination angle of the set back against the seat cushion is sustained.
