Claims

[Scope of utility model registration request]

A valve shaft having a locking convex portion formed in the center of one end;
A torsion bar, which is inserted into the center of the valve shaft along the axis and whose one end is connected to the valve shaft, and the engaging protrusion of the valve shaft are inserted, and as the valve shaft rotates through a predetermined angle, A stopper portion is formed that contacts the engagement convex portion, and is provided around a pinion shaft coupled to the other end of the torsion bar, and the valve shaft, and has one end externally fitted onto the pinion shaft. A power steering device including a valve sleeve that rotates integrally with the pinion shaft, including a notch formed in the one end of the valve sleeve and a ring groove formed in the inner circumferential surface of the one end of the valve sleeve. A claw piece is provided protrudingly on the outer peripheral surface to be inserted into the notch formed in the valve sleeve, and a protrusion is formed on the inner circumferential surface to come into contact with the stopper part of the pinion shaft, and a protrusion is formed at a position opposite to the protrusion. A power steering device comprising: a set ring fitted into a ring groove of the valve sleeve having a cut; and a stop ring fitted onto the valve shaft to restrict axial movement of the valve sleeve.
