PROBLEM TO BE SOLVED: To provide a wedge-shaped fastener for use in wedge fastening work capable of easily pressing a fastened item without hitting several times, positively press contacting the fastened item to a fastening part and fastening it.SOLUTION: A side surface 23 of a substrate 4 is provided with a plate-like member 5. There is provided a medium filling part 7 filled with medium 6 pressing against the plate-like member 5. There is provided a pressurizing mechanism 8 for pressurizing medium 6 filled in the medium filling part 7. When the medium 6 filled in the medium filling part 7 is pressurized by the pressurizing mechanism 8, the pressurized medium 6 presses against the plate-like member 5 from inside, the plate-like member 5 under pushed and compressed with medium 6 is bulged out and deformed in an outward direction or protruded outward and moved.SELECTED DRAWING: Figure 1 |
