Claims

[Scope of utility model registration request]

It has a pinion shaft provided with a stopper portion, a valve sleeve connected to the pinion shaft so as to rotate together with the pinion shaft, and a valve shaft connected to the pinion shaft via a torsion bar, wherein the valve shaft is When the valve shaft is displaced by a predetermined angle or more with respect to the pinion shaft, the valve shaft comes into contact with the stopper portion, and the rotation of the valve shaft is directly transmitted to the pinion shaft, and when the torsion bar is twisted, In the power steering device in which rotational displacement occurs between the valve shaft and the valve sleeve, a snap ring having a protruding portion on the outer circumferential surface is fitted onto the outer circumferential surface of the pinion shaft, and the stopper portion to regulate the position of the snap ring in the circumferential direction, a ring groove on the outer circumferential surface to regulate the position of the snap ring in the axial direction of the pinion shaft, and the valve sleeve has a convex portion shaped like the convex portion. A power steering device characterized in that the pinion shaft and the valve sleeve are connected by drilling a corresponding hole and inserting the convex portion into the hole.
