Claims

[Scope of utility model registration request]

An input shaft connected to the main shaft via a torsion bar, a cylinder that is interlocked with the main shaft and has a forward and backward moving direction cylinder 1, a second oil chamber, and an input shaft that is interlocked with the input shaft and moves in the axial direction of the input shaft. In a power steering device having a hydraulic switching valve that moves along the main shaft and switches hydraulic pressure supplied to the first and second oil chambers, a large diameter cylinder is provided integrally with the main shaft and formed to cover the outer periphery of the input shaft. Department,
A valve housing in which the large-diameter cylinder part and the hydraulic switching valve are installed, a pinion housing that fixes the valve housing and houses the main shaft, and a space between the pinion housing, the valve housing, and the large-diameter cylinder part. A power steering device comprising: an angular bearing disposed thereon, screwed onto an inner circumferential surface of the valve housing, and supported by the pinion housing.
