PROBLEM TO BE SOLVED: To provide a forced device of a wedge for pushing the wedge gripping a PC steel material into a fitting hole of a wedge receiver with power exceeding tension load in a fixing section of a PC structure. SOLUTION: The forced device of the wedge is the forced device of the wedge for pushing the wedge 2 gripping the PC steel material into the fitting hole 3TH of the wedge receiver (anchor disc 3A), and the forced device is equipped with a jack 10 placed so as to enable the wedge 2 to be pushed in the fitting hole 3TH and a pressure supporting member 20 subjected to reaction force in the case the wedge 2 is pushed in by the jack 10. The pressure supporting member 20 has a connecting member (PC steel rod 30) fixing one end to the anchor disc 3A as an immovable member and a pressure receiving member (pressure receiving plate 50) fixed to the other end of the connecting member and subjected to the reaction force.
