PROBLEM TO BE SOLVED: To provide fittings for fastening capable of preventing any subsequent rotation of a bolt or the like when fitting it, and also preventing firm sticking of its head portion and permitting easy sliding of the head portion during its use without causing any disengagement of fittings from a rail groove thereby permitting safe usage of the fittings for fastening without creating any derailing from the rail groove. SOLUTION: The fittings comprises: a disc-shaped head portion freely slidable in a longitudinal direction of a grooved portion having a convex cross section throughout an inner portion of a rod or board member; a circular cylindrical nut portion for bolt fitting formed eccentrically from a shank of the discoid head; and fitting members such as bolts. Thereby, fixation is made possible at any point in the grooved portion by tightening the fitting members toward the circular cylindrical nut portion. COPYRIGHT: (C)2008,JPO&INPIT
