PROBLEM TO BE SOLVED: To install an over-bending restriction piece with good space efficiency while preventing a spring piece from warping to deform.SOLUTION: A connection part 11 is cylindrical and has a tabular base wall 14. A cantilever type first spring piece 25 which bends toward the base wall 14 in contact with an opposite-side tab to deform is arranged in the connection part 11. The base wall 14 has a second spring piece 31, which is narrower than the first spring piece 25 and abuts against the first spring piece 25 from the side of the base wall 14, formed to project. Further, the base wall 14 has an over-bending restriction piece 36, which restricts the first spring piece 25 from over-bending by abutting against a free end part 27 of the first spring piece 25 from the side of the base wall 14, formed on both width-directional sides across the second piece 2 to project. |
