<P>PROBLEM TO BE SOLVED: To prevent a bearing ring of an oscillating bearing positioned in a housing from moving even when the bearing ring contacts a recessed arc-shaped part of the housing at a central part in the peripheral direction of an outer diameter face. <P>SOLUTION: A key groove 6 is provided on the outer diameter face 1b of the bearing ring 1, and the key groove 6 of the bearing ring 1 and a key groove 13 provided on the recessed arc-shaped part 11a of the housing 11 are engaged with a key 7 for positioning the bearing ring 1 in the housing 11. Therefore, even when the bearing ring 1 contacts the recessed arc-shaped part 11a of the housing 11 at the central part in the peripheral direction of the outer diameter face 1b, by the engagement of the key 7 with each of the key grooves 6 and 13, the movement of the bearing ring 1 can be restricted. <P>COPYRIGHT: (C)2008,JPO&INPIT |
