Claims

[Scope of utility model registration request]

A rack is formed on the piston slidably housed in the housing, and a sector gear of the sector shaft rotatably supported by the housing is formed to be inclined with respect to the axial direction of the sector shaft. The housing of the inserting device is configured to engage with the rack and rotate the sector shaft through the engagement portion by the sliding of the piston accompanying handle operation, thereby steering the steering wheel. Screw through the strike screw,
forming a screw hole in the end surface of the sector shaft opposite to the threaded portion, and bringing the end surface of the flange formed at the tip of the adjusting screw into contact with the bottom surface of the screw hole;
In a sector gear tension adjustment mechanism in which an adjustment nut is screwed into a threaded hole to regulate the axial movement of the sector shaft and adjust the stiffness of the meshing part, an adjustment nut that comes into contact with the bottom surface of the threaded hole is used. An adjusting member having a recess in which the flange portion is accommodated with a predetermined clearance in the axial direction is provided between the adjusting nut and the bottom surface of the screw hole, and is pressed against the bottom surface of the screw hole by tightening the adjusting nut. A sector gear backlash adjustment mechanism characterized by:
