Abstract: An object of the present invention is to provide a wheel drive device capable of suppressing a temperature increase in an electric motor and a power conversion device and suppressing occurrence of a failure of an electric component. Provided are: an electric motor having a stator 60 and a rotor 40; a stator holder 80 that holds the stator 60; a power conversion device 100 that converts power supplied to the electric motor; and a wheel which accommodates the electric motor, the stator holder 80, and the power conversion device 100 on the inner peripheral side. The stator holder 80 includes a flow path 90 through which a cooling medium flows. The flow path 90 is arranged between the stator 60 and the power conversion device 100.

Abstract: There is provided a control device for vehicles which can improve quietness and fuel economy, while maintaining high responsiveness to acceleration of a vehicle. Therefore, the control device 100 for vehicles includes a gear ratio control unit 10 that controls a gear ratio of a vehicle V, and a determination unit 20 that determines whether or not there is an acceleration limit of the vehicle V. The gear ratio control unit 10 is configured to limit an increase in gear ratio Rt, when the determination unit 20 determines that there is an acceleration limit.

Abstract: A steering apparatus includes: a pinion shaft coupled to a steering wheel and having a pinion; a rack shaft having a rack engaged with the pinion and a shaft back located on opposite side of the rack with an axial center of the rack shaft in between; a rack shaft housing that houses and slidably supports the rack shaft; and a rack shaft supporting mechanism having a pressure applying member that applies a pressure onto the shaft back toward the pinion. The shaft back includes a predetermined region provided across a midpoint of the rack which corresponds to a neutral position of the steering wheel. The predetermined region is a right-to-left steering wheel angle region having a height higher than a height of any other region of the shaft back.

Abstract: A steering device includes: a rack; a pinion; a pinion shaft having the pinion on an outer circumferential surface thereof; a rack shaft having the rack that engages with the pinion; a rack guide that is provided on a side of the rack shaft opposite from the pinion shaft and guides the rack shaft along an axis of the rack shaft; a biasing member that biases the rack guide against the rack shaft to press the rack against the pinion; a guide housing that accommodates the rack guide and the biasing member; and a buffer member provided between an outer circumferential surface of the rack guide and an inner circumferential surface of the guide housing. The buffer member has a cylindrical member and an elastic member. The elastic member is disposed on at least either one of an inner circumferential surface and an outer circumferential surface of the cylindrical member.
