PROBLEM TO BE SOLVED: To enable a coupling state when coupling a first half portion and a second half portion of a guide rail, to be surely and easily performed.SOLUTION: Each of half portions 7a, 7b of a guide rail 7 is formed as a resin molded body in which a conductive material 24 is buried. The conductive material 24 includes upper and lower connecting terminal parts 26 and 27 provided in an opening edge of an insertion part 21, and a lead wire 28 connecting the connecting terminal parts 26 and 27. When the half portions 7a, 7b are coupled with each other, the conductive material 24 of the first half portion 7a and the conductive material 24 of the second half portion 7b form an electrical closed circuit. |
