<P>PROBLEM TO BE SOLVED: To provide a fixing structure for a bearing capable of preventing preload on rolling elements positioned in a V-groove from changing in a structure fixing a rolling element guide member of a bearing on a fixed member by fastening together between the fixed member and a stator by a bolt. <P>SOLUTION: Since a cross roller bearing 23 does not includes a parting surface of which axis crosses an outer ring 29 and an inner ring 30 at right angle, and the outer ring 29 or the inner ring 30 of the cross roller bearing 23 is formed in a shape with which a pressing direction projection surface of a pressing section of the stator is out of the V-grooves 29a, 30a, press force does not act on the V-grooves 29a, 30a of the outer ring 29 and the inner ring 30 of the cross roller bearing 23 even if the cross roller bearing 23 is fixed between the fixed member and the stator under a gripped condition by firmly fastening the bolt. <P>COPYRIGHT: (C)2010,JPO&INPIT |
