After the reinforcement 12 is brought to the first support plate 211, the reinforcement 12 is not pressed against the first protrusion 212b, and the jaw main body 212a is restored under the elastic restoring force, so that the first protrusion 212b catches the reinforcement 12 in the second direction Z.
