<P>PROBLEM TO BE SOLVED: To maintain stable creeping resistance while maintaining good performance of insertion into a housing. <P>SOLUTION: In the outer diameter face of an outer ring 1, a pair of recessed grooves 10 in annular shape are formed along the peripheral direction. Into the pair of recessed grooves 10, O-rings 11 in annular shape are fitted whose outer diameter faces are protruded from the recessed grooves 10, respectively. An interference relationship between an inner diameter D2 of the O-ring 11 and a diameter D1 of the recessed groove 10 in the outer diameter face of the outer ring 1 is set to satisfy D1≥1.07×D2. <P>COPYRIGHT: (C)2008,JPO&INPIT |
