MOTION GUIDE DEVICE

摘要

A motion guide device can prevent a seal lip part of an end seal member from being caught in an insertion hole of a track rail and thereby prevent abrasion or damage of the seal lip part, and can also reduce transfer resistance of a transfer block with respect to the track rail. The motion guide device comprises: a track rail (1) which has an insertion hole (12) for an attachment bolt formed therein; and a transfer block (2) which is attached to the track rail (1) with a large number of rolling bodies (3) therebetween. An attached-matter passage (40) is provided in the transfer block at a position facing the insertion hole (12) of the track rail (1) so that matter attached to the track rail can pass from one end to the other end of the transfer block (2). In addition, a pair of passage-forming members (4) are fixed to both ends of the transfer block (2) in the transfer direction. The passage-forming members comprise: a pair of end seal members (41) which traverse rolling-body roll surfaces of the track rail and also make contact with the surface of the track rail; and a passage opening (42) which is provided between the end seal members and also forms an entrance of the attached-matter passage.
