PURPOSE: An infinitely variable clamp is provided to freely adjust tightening width of a C-shaped clamp to cope with various condition. CONSTITUTION: A clamp comprises a body(21); a fixed part(31); and a tightening part(11). The body is made of linear member such as linear steel pipe, annular rod and H-beam. The length of the body is freely adjustable to infinitely extend coupling range of the clamp. The fixed part is coupled on any point on the body by steel pipe clamps(16A,16B). The tightening part has a tightening device comprising screws. The tightening part is coupled on any point on the body by steel pipe clamps(16C,16D). The tightening device comprises a tightening part contacting surface(13), a fixed screw part(12), a moving screw part(14) and a handle(15).
