PROBLEM TO BE SOLVED: To provide a forming apparatus using hydroforming which is free from positional variation of a nozzle to a base stock to thereby enable the quality and the formability of formed goods to be improved and the nozzle life to be prolonged. SOLUTION: The forming apparatus 10 using hydroforming has a nozzle 40 which is provided with the nose part 42 which is inserted into the tubing material 21 as the base stock 20 and in which a passage 44 through which a medium for adding internal pressure flows down is formed, guide unit 50 which is attached to a lower die 32 and with which the movement of the nozzle is guided in a state where the unit is centered to the tubing material, medium injecting horse 60 which is connected to the nozzle freely attachably and detachably, shaft pushing cylinder unit 70 for imparting pressing force for inserting the nose part of the nozzle into the tubing material to the nozzle, and key-shaped connecting member 80 for connecting the nozzle to the shaft pushing cylinder unit freely attachably and detachably. The connection of the nozzle to the shaft pushing cylinder unit with the connecting member is performed in a state where the nozzle is held with the guide unit. COPYRIGHT: (C)2005,JPO&NCIPI
