PROBLEM TO BE SOLVED: To solve the problem of a mode of use in an inclined state seen in most fields of roofing and tiling, wherein suspending support using a locking hook involves risk of slippage and falling. SOLUTION: A locking hook 2 arranged on a nailer 1 is mounted in a longitudinal direction of a body of the nailer 1. At least either end of the hook 2 has jaws lockable on a support member. The jaws firmly lock the nailer 1 on the support member. Once supported on the support member, the nailer 1 can be reliably and firmly supported against slippage and falling.
