Claims

[Claims for Utility Model Registration] An input shaft 5 connected to a steering wheel 4 and a pinion shaft 7 that meshes with a rack bar 10 are coupled via a torsion bar 11, and a sleeve 12 that rotates together with the pinion shaft 7 and the In a rotary valve for a power steering device that switches an oil path connected to a power cylinder 16 by relative rotation of an input shaft 5, the sleeve 12 is supported on the outer periphery of the input shaft 5 so as to be freely slidable in the axial direction.
Clutch surfaces 5 _{2 ,} 12 ₅ are formed on the input shaft 5 to be crimped by sliding of the sleeve 12 , and a control means 20 is provided for changing the crimping force of the clutch surfaces 5 ₂ , 12 ₅ . Rotary valve for power steering equipment.
