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