Claims

[Scope of utility model registration request]

A steering gear mechanism having a pinion shaft connected to a steering wheel, a rack meshing with the pinion shaft and connected to a steering wheel, and a housing supporting the pinion shaft rotatably and movably in parallel to the displacement direction of the rack. a power cylinder installed in the rack and configured to increase the steering force applied to the steering wheel by the action of pressure fluid and transmit the increased steering force to the steered wheels; A power steering system comprising: a spool that is linked to the pinion shaft via a lever and is displaced as the pinion shaft moves in parallel; and a control valve that controls pressurized fluid supplied to the power cylinder by displacement of the spool. In the apparatus, a bearing having a hole through which the pinion shaft is rotatably inserted is interposed between the pinion shaft and the housing, and the bearing is divided into a plurality of members in a circumferential direction of the hole. and setting members that are displaced in the movement direction as the pinion shaft moves in parallel, and each member is elastically coupled by an elastic body so as to be in elastic contact with each other, and
The mounting position of the bearing in the axial direction of the pinion shaft and the elastic force of the elastic body that urges the member are determined by the moment centered on the meshing part with the rack that is generated by the member to the pinion shaft when the pinion shaft moves in parallel. A power steering device characterized in that the power steering device is configured to act in a direction opposite to the moment caused by the centering spring.
