Abstract

The purpose of this invention is to realize reduction in the operating noise of an electric power steering device at a low cost, and to enhance the reliability of fixing a sound absorbing material by a simple structure. The electric power steering device (1) comprises an electric motor (10) having a motor housing (11), a control device (31) for controlling the electric motor (10), a casing (32) in which the control device (31) is stored, a sound absorbing material (60) disposed on the outer periphery side of the motor housing (11) and a fixing member (70) for holding the sound absorbing material (60) from its outside, and the fixing member (70) is secured to the casing (32).
