摘要

PROBLEM TO BE SOLVED: To align a pair of track members and a joint member to cover a part therebetween on the same plane by fixing one end of the joint member to one track member, and fixing the other end to the inner side of the other track member through a tension member. ;SOLUTION: A joint member 10 is provided between track members 7, 8 so as to cover a clearance 9 between adjacent track members 7, 8, a steel end member 11 is provided on the end of the track member 7, and an end member 12 is provided on the end of the track member 8. One end of a strip-like stainless steel joint member 10 is fixed by screws to an upper surface of the end member 11 so that a center part of the joint member 10 is located on the clearance 9. Then, the other end side of the joint member 10 is located on a first plate 14a of the end member 12, and further located in an inner chamber 13 through a slit 15, and the other end of the joint member 10 is pulled inside the inner chamber 13 by the tension of a tension spring 16. Thus, an upper surface of one track member 7, an upper surface of the joint member 10, and an upper surface of the other track member 8 are existing on the same plane.;COPYRIGHT: (C)1999,JPO
