リング装置。 An electric power steering device that includes a steering system that transmits the rotation of a steering wheel to the steered wheels via a shaft member that is supported by a case so as to be axially displaceable, and an electric motor that generates auxiliary torque to the steering system. , a cylindrical member that is surrounded by a gap around the outer periphery of the shaft-like member, is supported by the shaft-like member in a relatively non-rotatable manner, and has a spiral groove on its outer peripheral surface; A ball screw is constituted by a nut member which is rotatably supported by a case and has a spiral groove on its inner circumferential surface, and a ball interposed between the spiral grooves of the cylindrical member and the nut member. An electric power steering device characterized in that a nut member of a ball screw is connected to a rotating shaft of the electric motor so that rotation can be transmitted.
