ARM STOPPER MECHANISM MOUNTING APPARATUS AND STEERING APPARATUS USING SAME

摘要

Disclosed is an arm stopper mechanism mounting apparatus including: an output shaft; a housing that is provided with a hole for inspecting the sealability of the interior thereof; a sealing member that seals the hole, and can be detached from the hole when the sealability is inspected; and an arm stopper mechanism that has a steering arm and a stopper. The steering arm includes an output shaft hole into which the output shaft is fitted; two tie rod holes to which the tie rods are respectively attached; and two striking surfaces which strike against the stopper. The stopper includes two contact surfaces. An angle made by the two contact surfaces of the stopper is greater than an angle made by the two striking surfaces of the steering arm, and is 90° or greater.

1. An arm stopper mechanism mounting apparatus comprising:
an output shaft that outputs a steering force to wheels of a vehicle; a housing that is provided with a hole for inspecting a sealability of an interior of the housing, and turnably accommodates the output shaft; a sealing member that seals the hole, and is detachable from the hole when the sealability is inspected; and an arm stopper mechanism that comprises
a steering arm which turns about the output shaft while being positioned near a lower surface of the housing, and to which two tie rods, to which the wheels are respectively connected, are attached, anda stopper which is provided in a vicinity of the output shaft, and restricts an angle of the turning of the steering arm, wherein when an imaginary straight line that passes through the output shaft and extends in a longitudinal direction of the vehicle is defined as a center line of the steering arm, the steering arm comprises, in a neutral state: an output shaft hole which is provided on the center line, and into which the output shaft is fitted; two tie rod holes which are respectively provided at positions that are separated by a distance from the center line to a right and a left, and that are separated by a distance from the output shaft hole to a rear side of the vehicle, and to which the tie rods are respectively attached; and two striking surfaces which are respectively provided at positions that are separated by a distance from the center line to a right and a left, and that are separated by a distance from the output shaft hole to a rear side of the vehicle, and which are to strike against the stopper, the stopper comprises two contact surfaces that are respectively provided at positions that are separated by a distance from the center line to a right and a left, and that are present in a turning direction of the striking surfaces of the steering arm, and that are respectively to be brought into contact with the striking surfaces, and wherein an angle made by the two contact surfaces of the stopper is greater than an angle made by the two striking surfaces of the steering arm, and is 90° or greater.
