Abstract
A power steering system is provided which makes it possible to simplify assembly onto a vehicle body and to enhance assembly accuracy. A steering shaft is divided into two portions in the axial direction. The lower of the two portions is an input shaft. A connecting cylinder to which the input shaft is serration-fitted is integrally provided at a lower portion of the steering shaft. A side wall of the connecting cylinder is provided with a groove in the axial direction. A fastening device is provided for reducing the diameter of the connecting cylinder so as to reduce the width of the groove. A spool lever is integrally fitted to the input shaft.

- a connecting cylinder, to which said input shaft is serration-fitted, is integrally provided at a lower portion of said steering shaft,
- a side wall of said connecting cylinder is provided with a groove in the axial direction,
- fastening means is provided for reducing the diameter of said connecting cylinder so as to reduce the width of said groove, and
- said spool lever is integrally fitted to said input shaft.
A power steering system, comprising:
- a steering shaft rotatably fitted to a vehicle body frame, said steering shaft being divided in the axial direction into a lower section and an upper section,
- said lower section comprising an input shaft;
- said upper section comprising a connecting cylinder integrally provided at a lower portion of said steering shaft, said connecting cylinder being serration-fitted to said input shaft;
- a power assist cylinder provided between said steering shaft and the vehicle body frame;
- a control valve operated by said steering shaft to control said power assist cylinder;
- and
- a spool lever integrally fitted to said input shaft of said steering shaft for operating said control valve.
A power steering system for a vehicle, comprising:
- a frame;
- a steering shaft rotatably fitted to said frame, said steering shaft including a connecting cylinder integrally provided at a lower portion of said steering shaft, said connecting cylinder including a female spline fitting therein;
- an input shaft including a male spline fitting which is received in said female spline fitting of said connecting cylinder;
