PROBLEM TO BE SOLVED: To provide a mounting structure of a support member by which a guide has to be slid little and the support member can be fixed to the optional position of a rail. SOLUTION: A guiding groove 2 of the rail 1 is obtained by forming upper and lower circular-arc surfaces 2a symmetrically and forming its opening to be narrow. The cross-sectional shape of the guide 3 is formed to be elliptic by making upper and lower circular-arc surfaces 3a symmetrical with each other. The horizontal side of the elliptic shape is smaller than the opening width of the guide groove 2, and the vertical size is larger than the opening width of the guide groove 2 and smaller than a width inside of the groove. A screw hole 15 is bored on the lateral side face of the elliptic shape. By fitting the guide 3 facing sideway to the guide groove 2 from its front face side and rotating this by 90°, the guide 3 is fitted to the guide groove 2 at an optional position. By making its lateral side face face the opening side of the guide groove 2 and a support bar 5 is screwed to the screw hole 15 bored at this lateral side face, the support bar 5 can be fixed to the optional position of the rail 1.
