Kind Code:
A1
Abstract:
In the power steering apparatus of the present invention, regarding a locknut (12) serving as a fixing member, a fixing portion (122) for fixing the outer race (111) of a ball bearing (11) has a portion which overlaps with a facing portion (121) facing the outer race (111) in the direction of the rotation axis (Z) of a nut (941), and is provided radially on an outer side than the facing portion (121). Accordingly, the amount of protrusion of the locknut (12) towards the output-side pulley (92) side is suppressed and the output-side pulley (92) and a belt (93) can be arranged closer to the ball bearing (11) side, as a result of which friction in the ball bearing (11) can be reduced.
