Abstract
Reduces backlash and clearance in a thrust direction of a worm when engaging a seat back to more securely prevent the generation of abnormal noise that before. A movable bearingis pressed by camsthat are pressing members, when the seat back is stopped at a predetermined angle, to approach a worm wheel. A balldisposed in a recessof the movable bearingmoves slightly along an inner surface of the recessso a wormis pressed to the worm wheelside and pressed to the fixed bearingside, and a latch memberthat is a engaging member engages the wormto inhibit rotation of the worm wheelthereby securely holding that state. Since the movable bearingmoves to the worm wheelside, the substantial movement range of the ball is wider compared to a structure that supports a ball only at a fixed bearing, and the range of displacement of the wormby being pressed by the ball is substantially larger.
