PURPOSE:To enable a positive and easy removal of channel members one by one which are stacked up at a mounting place by a method wherein there are arranged some projections facing to an opening at the bottom part of a channel member. CONSTITUTION:A convex part 9 is arranged at the central part of a bottom face 4 of the main body 13 of a channel member. Projections 11a, 11b with their both ends being bent to form a convex shape are integrally formed at the fitting base part 10 arranged around the fitting parts 9, and on the upper surfaces of the projections are formed flat surfaces 12a, 12b. The height of projections 11a, 11b is set larger than the height size of the fitting member 9. Therefore, in case of stacking of channel member C, the lower surface 7 at the bottom part 4 of the upper channel member Cu is abutted against the flat surfaces 12a, 12b of projections 11a, 11b at the lower channel member Cl, the fitting parts 9 for the lower channel member Cl is not contacted with the upper channel Cu and at the same time a clearance size H1 between the upper and lower channel members Cu, Cl is kept constant. |
