<P>PROBLEM TO BE SOLVED: To provide a motion guide device for preventing abrasion and a chipped part of a seal lip part, and reducing moving resistance of a moving block to a track rail, by eliminating a phenomenon that the seal lip part of an end seal member hitches on an insertion hole of the track rail. <P>SOLUTION: The motion guide device has the track rail for forming the insertion hole 12 of an installation bolt and the moving block installed on the track rail via a large number of rolling elements. In the moving block, a sticking object passage for passing a sticking object of the track rail to the other end from one end of the moving block, is arranged in an opposed position of the track rail to the insertion hole 12, and a pair of passage forming members 4 are also fixed to both ends in the moving direction of the moving block, and such the passage forming parts 4 have a pair of end seal parts 41 for crossing a rolling element rolling travel surface 11 of the track rail and abutting on a surface of the track rail and a passage opening part 42 arranged between these end seal parts 41 and forming an inlet of the sticking object passage. <P>COPYRIGHT: (C)2012,JPO&INPIT |
