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.

Steering apparatus

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.
