<P>PROBLEM TO BE SOLVED: To provide a cross roller bearing in which an insertion hole and an embedded plug are easily worked and positioning accuracy is improved by forming the insertion hole at the upper part of an inner ring or an outer ring and forming tapered parts on side faces of the embedded plug blocking the insertion hole. <P>SOLUTION: The U shape insertion hole 6 having radial direction inside faces 61, 62 and a peripheral direction inside face 63 is formed at the upper part of the inner ring 3 or the outer ring 2 of the cross roller bearing 1, the embedded plug 7 having a rolling contact surface 70 on which cylindrical rollers 5 roll, two radial direction outer faces 71, 72, and a peripheral direction outer face 73 and of a rectangular shape when viewed in the axial direction, is fittingly fixed into the insertion hole 6, and the radial direction outer face 72 abutting on the radial direction inside face 62 of the insertion hole 6 and the peripheral direction outer face 73 abutting on the peripheral direction inside face 63 are formed in a tapered shape positioning in the radial direction and the peripheral direction. <P>COPYRIGHT: (C)2011,JPO&INPIT |
