BEARING BUSH AND COMPOUND MOVEMENT DEVICE USING THE SAME

WIPO Patent Application WO/2005/103516

A1

A bearing bush enabling the excellent advancing and retarding motions of a shaft member by eliminating a clearance between the bearing bush and the shaft member to exclude rattling therebetween, capable of reducing a load on dimensional control for both the bearing bush and the shaft member, and manufacturable at low cost and a compound movement device using the bearing bush. The bearing bush (4) pivotally supporting the reciprocating motion of the shaft member (1) in the axial direction comprises an accepting hole through which the shaft member (1) is inserted. Grooves (40) are repeatedly formed, at specified intervals, in the inner peripheral surface of the bearing bush which faces the accepting hole. The inner diameter of the accepting hole is formed equal to or smaller than the outer diameter of the shaft member (1) to press-fit the bearing bush to the outer peripheral surface of the shaft member (1) by so-called a shrink fitted state.
