Claims

[Scope of utility model registration request]

An input shaft 3 rotatably supported by a bearing 2 inside the housing 1, a torsion bar 5 having one end fixed to the input shaft 3 with a pin 4, and a pin attached to the other end of the torsion bar 5. an output shaft 8 which is fixed by an output shaft 6 and rotatably supported inside the housing 1 by a bearing 7;
A valve 9 is rotatably and slidably fitted between the inner periphery of the housing 1 and the outer periphery of the input shaft 3. One end is fitted into a long groove 10 provided in the valve 9, and the other end is fitted into a long groove 10 provided in the valve 9. By coupling to the output shaft 8, the output shaft 8
and an output shaft-valve coupling pin 11 that integrally connects the valve 9 in the rotational direction, and drives the valve 9 by the relative rotational displacement between the input shaft 3 and the output shaft 8 to generate hydraulic pressure. In a power steering device that performs control, the output shaft-valve coupling pin 11 has a threaded portion 11 that is screwed into a pin receiving hole 8a provided in the output shaft 8.
a, and a cam portion 11b for fitting into a long groove, which is provided eccentrically at the tip of the threaded portion 11a.
