PROBLEM TO BE SOLVED: To provide an electric power steering device capable of suppressing rapid temperature rising at the inside of a motor by efficiently releasing the heat generated in the motor with the brush, in particular, near an electricity-feeding brush to the outside and attaining enhancement of durability of a motor with a brush by prolonging the time when it arrives at the limit temperature. SOLUTION: A heat conductive member having heat conductivity is inserted to a bracket of the motor with the brush assembled to a gear box of a deceleration mechanism, and one end surface of the heat conductive member and a back surface of a brush holder for storing/retaining the electricity-feeding brush of the motor with the brush are connected to each other through an insulation member having heat conductivity.
