Abstract:
To provide a wedge fastening device used at a scaffold such as temporary scaffold.SOLUTION: A wedge member is moved downward from a standby position to a fastening position and fastened by being driven into a fastening hole of a flange. A holding means (37) receives a stopper portion (36) protruding from an idler surface (34) of a branch part (16B) of the wedge member and consists of a fixed wall (42) facing the idler surface (34) and a wire bent body (39) made of a spring wire. The wire bent body forms a holding portion (46) by bending a tip of an elastic arm (45) spliced on an outside surface of the fixed wall in an arch shape toward the idler surface (34). The holding portion is displaced in a direction separating away from the idler surface through elastic deformation of the elastic arm.SELECTED DRAWING: Figure 2
