摘要： A clearance is created between an inner circumference of a bushing main body (2) which surrounds a rack (5) across a row of rack gear teeth (50) and an outer circumference of the rack (5), and two supporting surfaces (21A, 21B) which face each other with a bushing main body axis O therebetween and a supporting surface (21C) which faces a back surface of the rack (5), each extending along an x-axis direction, are formed on the inner circumference of the bushing main body (2). The rack (5) in a neutral state is supported by the two supporting surfaces (21A, 21B) so as to be displaceable along a z-axis direction, and the rack (5) in operation is stably supported by the three supporting surfaces (21A-21C) at three places. A groove bottom position of an annular elastic member attachment groove (24), which is formed on an outer circumference of the bushing main body (2), is offset toward the support surface (21B) only in an area on a support surface (21B) side from the bushing main body axis O, and therefore an elastic ring (3) attached to the elastic member attachment groove (24), protrudes above an outer circumferential surface of the bushing main body (2), but only in the area on the support surface (21B) side from the bushing main body axis O.

摘要： 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.
