Abstract

A sliding bearing for a steering column includes: a cylindrical bearing body (2); flat surfaces (4) formed integrally on an inner peripheral surface of the bearing body; first slits (7) extending from one end face (5) of the bearing body to this side of the other end face (6) of the bearing body; second slits (8) extending from this side of the other end face (6) of the bearing body to the one end face (5) of the bearing body; grooves (10) formed in an outer peripheral surface of the bearing body (2); and elastic rings which are respectively fitted in the grooves in such a manner as to project from the outer peripheral surface of the bearing body (2) and to reduce the diameter of the bearing body.

Description

technical field [0001] The present invention relates to a sliding bearing inserted between, for example, a steering column tube and a steering column shaft for rotatably supporting a steering column shaft of an automobile, a sliding bearing inserted between a rack shaft and a tubular member for linearly movable A sliding bearing for ground-supporting a rack shaft, and a bearing mechanism having such a bearing. Background technique [0002] A rolling bearing made of a ball bearing or a sliding bearing made of synthetic resin is used as a bearing for a steering column (hereinafter referred to as a column shaft) for rotatably supporting a steering column shaft of an automobile. [0003] In general, rotational conditions such as load and rotational speed are not so critical for bearings for rotatably supporting a steering column shaft. However, there are requirements for vibration absorbing characteristics for absorbing vibrations acting on the column shaft and stability of fri...
