摘要：PURPOSE: A coupling for connection an oil pressure rubber hose having an eccentric revision ability is provided to prevent a crack caused by eccentricity. CONSTITUTION: A tightening nut part comprises connection ripples and a connection pipe body. A coupling(300) fastens the outer surface of a rubber hose. A fastening element is arbitrarily rotated in state one end of the fastening element is covered by the connection ripples. An engagement surface(310) comprises engagement protrusions(320). A tightening surface(340) has a protruded jaw(350) in the inner circumference. Concave groove parts(360) are inserted from the point that the engagement surface is finished to a curved surface(330) and the outer surface of the tightening surface at equal intervals.
