<P>PROBLEM TO BE SOLVED: To provide a finite rolling motion guide device which can maximally take an operation stroke of a second member with respect to a first member by forming differences at contacting diameters of rolling bodies with respect to rolling traveling faces of the first member side and the second member side. <P>SOLUTION: In the finite rolling motion guide device having balls 7 as the rolling bodies which are rollingly interposed between ball rolling traveling grooves 4, 6 formed at an opposite face between a raceway rail 3 and a moving block 5, and a cage 9 for holding the balls 7, the contacting diameters d<SB POS="POST">2</SB>of contacting parts C<SB POS="POST">11</SB>, C<SB POS="POST">12</SB>contacting with the ball rolling traveling groove 6 at the moving block 5 side of the balls 7 are set smaller than the contacting diameter d<SB POS="POST">1</SB>of a contacting part C<SB POS="POST">0</SB>contacting with the ball rolling traveling groove 4 at the raceway rail 3 side of the balls 7. <P>COPYRIGHT: (C)2013,JPO&INPIT |
