PURPOSE: To easily prevent the occurrence of abnormal angle breaking as well as easily shield noise by a method in which an interpositional part to expand or contract along a circular arc locus where connecting part is centered on the joint between guide way beams is provided.
CONSTITUTION: Guide way beams 1 are connected with a pin 2, and an outer guide 11 is provided to one end of the beams 11 and a claw 13 is provided to the other end of the beams 1. The guide 11 and the claw 13 are connected with a guide 12 slidably moving between the guide 11 and the claw 13, where they are set along the circular arc locus where the pin 2 is centered. They are moved slidably to expand or contract between the guide way beams 1 and the length of the guide l1 and the claw 13 is matched with the distance between the beams 1. By shielding between the beams 1, the occurrence of abnormal angle breaking is prevented and noise can also be prevented.
