Motor-driven type power steering apparatus

摘要

A motor-driven type power steering apparatus includes: a drive gear (3) connected to an output shaft (1a) of a motor (1); a driven gear (4) in mesh with the drive gear (3), which is connected to a steering unit; a bearing (8) for supporting one end (36) of the drive gear (3); a support portion (74) in which the bearing (8) is disposed; and a curved leaf spring (12) which has a length larger than a peripheral length of the bearing (8) and fitted between the bearing (8) and the support portion (74) in a resiliently deformed state. The curved leaf spring (12) urges the bearing (8) so that a distance between an axis of the driven gear (4) and an axis of the drive gear (3) decreases.
