When the wedge is driven into the wedge insertion holes in the condition where the catch portion is opposed to the supporting piece, the hook is retracted with the result of engagement of the catch portion with the supporting piece, whereas end portions of the wall bodies are pushed outward into contact with the outer surface of the columnar member. |
