Abstract

A slide bearing which can be manufactured at low cost is provided. The slide bearing ( 1 ) is provided with a cylindrical bearing main body ( 2 ) into which a shaft member is inserted, and an elastic ring ( 3 ) for urging the bearing main body ( 2 ) diametrically inward, the elastic ring ( 3 ) being mounted to the bearing main body ( 2 ). The bearing main body ( 2 ) has a sliding surface ( 21 ) which slides against the outer peripheral surface of the inserted shaft member, a plurality of first slits ( 25 ) running along the direction of an axis O from one end surface ( 23 ) toward another end surface ( 24 ), a plurality of second slits ( 26 ) running along the direction of the axis O from the other end surface ( 24 ) toward the one end surface ( 23 ), a plurality of first elastic ring interlocking parts ( 27 ) protruding diametrically outward at one end part ( 220 ) of the outer peripheral surface ( 22 ), and a plurality of second elastic ring interlocking parts ( 28 ) protruding diametrically outward at another end part ( 221 ) of the outer peripheral surface ( 22 ). The first elastic ring interlocking parts ( 27 ) and the second elastic ring interlocking parts ( 28 ) are positioned so as not to overlap each other seen in an imaginary plane P perpendicular to the axis O.

First claim

The invention claimed is:

1. A slide bearing for supporting a load applied to a shaft member while allowing movement of the shaft member, comprising:
a tubular bearing main body into which the shaft member is inserted; and
an elastic body which is mounted on the bearing main body and biases the bearing main body radially inward, wherein:
the bearing main body comprises:
slits which are formed along axial direction from one end surface toward other end surface;
first elastic body locking parts which are formed on a side of one end of an outer peripheral surface and protrude radially outward; and
second elastic body locking parts which are formed on a side of other end of the outer peripheral surface and protrude radially outward, and
the first elastic body locking parts and the second elastic body locking parts are located at positions which do not overlap each other seen in an imaginary plane perpendicular to an axis of the bearing main body.

2. A slide bearing of claim 1 , wherein:
the bearing main body is made of synthetic resin.

3. A slide bearing of claim 2 , wherein:
the elastic body is made of rubber or elastic synthetic resin.

4. A slide bearing of claim 2 , wherein:
the elastic body is made of rubber or elastic synthetic resin.
