Abstract: A reducer of an electronic power steering apparatus is disclosed. The reducer of an electronic power steering apparatus aids the operation of a steering wheel by the driver by preventing a clearance from being caused by frictional wear between a worm and a worm wheel, by reducing rattle noise caused by backlash, and by minimizing the change in the clearance due to a change in torque.

Abstract: A gear shift device is provided which changes speed by transmitting rotation of a shift spindle by gear shift operation input to rotation of a shift drum through an intermittent feed mechanism and a lost motion mechanism. An upstream rotation holding mechanism is provided to hold in a required rotational position an upstream rotating member of the lost motion mechanism which is rotated by gear shift operation input through the intermittent feed mechanism. When a required level of gear shift operation is done, the gear shift device changes speed adequately, without continuing gear shift operation, and thus improves operability.

An inner ring is seated on an outer peripheral surface of the hub and has one or more inner race surfaces thereon. An outer ring is formed with outer race surfaces as many as inner race surfaces formed at the hub and the inner ring. Rolling elements are disposed between the outer race surfaces and the inner race surfaces. Cages are disposed to maintain circumferential intervals of the rolling elements. The outer ring is formed with three or more outer race surfaces. The rolling elements are arranged in three or more rows. The arrangement of multiple-row rolling elements enhances the life of the bearing. Manufacturing costs are curtailed and rolling resistance is reduced compared to the tapered roller bearing.
