Claims

[Claims for Utility Model Registration] (1) An input shaft rotated by a steering wheel, an output shaft arranged on the same axis as this input shaft and capable of relative rotation, and an integral rotation of both shafts. a control valve consisting of a valve member that is movable, and a reaction force mechanism provided between the two shafts, the reaction force mechanism being configured to act on one of the shafts or on a member that rotates integrally with the shaft. a radial hole formed, a reaction plunger slidably fitted into the hole and having a spherical portion at its tip, and the other shaft or a member that rotates integrally with the shaft;
A power steering device comprising a substantially V-shaped groove in contact with a spherical portion of the reaction plunger, wherein a recess is formed at the tip of the reaction plunger to hold a ball in the recess; Let be an arc with a radius larger than the radius of the ball, and
A power steering device characterized in that the center of this arc is offset from the axis of the reaction plunger. (2) An input shaft rotated by the steering handle, an output shaft arranged on the same axis as the input shaft and rotatable relative to each other, and a valve member provided on each of these shafts so as to be integrally rotatable. and a reaction force mechanism provided between the two shafts, the reaction force mechanism including a radial hole formed in one of the two shafts or a member that rotates integrally with the shaft; a reaction force plunger that is slidably fitted into the hole and has a spherical portion at its tip, and the other shaft or a member that rotates integrally with the shaft;
In the power steering device comprising a substantially V-shaped groove in contact with the spherical portion of the reaction plunger, a plug is fitted to the outer periphery of the reaction plunger so as to be relatively rotatable, and the plug is inserted into the radial hole. A power steering device characterized in that the axial center of the plug and the axial center of the reaction force plunger are eccentrically fitted together with each other.
