| 发明名称 | Steering device | ||
| 摘要 | 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. | ||

| 主权项 | 1. A steering device comprising: a rack; a pinion; a pinion shaft that has the pinion on an outer circumferential surface thereof; a rack shaft that has 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 that is provided between an outer circumferential surface of the rack guide and an inner circumferential surface of the guide housing, wherein the buffer member has a cylindrical member and an elastic member, the elastic member being disposed on at least either one of an inner circumferential surface and an outer circumferential surface of the cylindrical member; and the elastic member includes a first elastic member, and a second elastic member having an modulus of elasticity smaller than that of the first elastic member, and the second elastic member is disposed on the pinion shaft side and the rack shaft side with respect to the first elastic member. | ||
