ELECTRIC POWER STEERING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an electric power steering device capable of preventing a rapid temperature increase of a brush at a low cost by improving radiation of heat generated especially around the brush in a motor, and extending time until it reaches the limiting temperature of the brush. SOLUTION: This electric power steering device assist-steers a steering shaft by driving the motor with the brush through a deceleration mechanism. A brush holder stay for fixing the brush holder is attached at the bracket for the motor with the brush, and a filler is interposed between the brush holder and the bracket.
