PURPOSE: A coupling structure of a bumper is provided to couple a radiator grill and a deco-member with a first and a second coupling member, thereby preventing gaps and stepped portions on an assembly from being generated. CONSTITUTION: A coupling structure of a bumper comprises a bumper cover(10), a radiator grill(20), a deco-member(30), a first coupling member(40), and a second coupling member(50). An external air enters the radiator grill coupled to the bumper cover. The deco-member is coupled to the radiator grill. The radiator grill is coupled to the deco-member with the first coupling member. The first coupling member is coupled to the bumper cover with the second coupling member. A hook protrusion(43) hooked on the deco-member is formed outside the first coupling member. A first spiral(45) through which the second coupling member is inserted into, and fastened to the first coupling member is formed inside the first coupling member. A second spiral(55) fastened to the first spiral is formed outside the second coupling member. The first coupling member includes a hook portion(42) at which the hook protrusion is formed, and an extended portion(44) into which the second coupling member is inserted. The extended portion extended from the hook portion penetrates the deco-member and the radiator grill, and then protrudes from the radiator grill. The extended portion is inserted into the bumper cover.
