<p><P>PROBLEM TO BE SOLVED: To provide a structure capable of preventing circumferential edge parts of cage elements 17a, 17a constituting a split type cage 7a from easily scratching a lubricant adhering to an outer ring raceway. <P>SOLUTION: Inclined surface parts 18, 18 each inclined in a direction headed toward an inner diameter side as it approaches an edge are formed at both circumferential ends of the outer peripheral surfaces of both the cage elements 17a, 17a. By the presence of gap spaces based on the presence of the respective inclined surface parts 18, 18, both the circumferential edges of both the cage elements 17a, 17a are prevented from scratching a lubricant adhering to the outer ring raceway even in the state where both the circumferential ends of the outer peripheral surfaces of both the cage elements 17a, 17a contacts the outer ring raceway, and the above problem is solved. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
