A front stay member is inserted into a through-hole in a bumper reinforcement. A first end of a middle stay member is fitted onto a portion of the front stay member that protrudes from the through-hole until the first end of the middle stay member comes into contact with the bumper reinforcement. A rear stay member is inserted into a second end of the middle stay member until the second end of the middle stay member comes into contact with the step on the rear stay member. A magnetic field shaper is disposed so as to face portions of an outer peripheral surface of the middle stay member that respectively overlap the front stay member and the rear stay member, and the middle stay member is clinched onto the front and rear stay members by applying an electromagnetic force to the magnetic field shaper.
