RACK BUSHING AND STEERING DEVICE

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...

Beschreibung
Zusammenfassung:	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.
