PURPOSE:To simplify and miniaturize the constitution by pouring and discharging a pressure fluid by interposing a hose like member formed by a flexible material between a table and work member. CONSTITUTION:When compressed air is poured into an air hose 24 via a connector 26 from an electromagnetic valve, the air hose 24 is expanded to push up a sliding member 22, a metal plate is squeezed between an upper die 19 and lower die 17 and bending is executed. At this time, the air hose 24 is lifted up together with the sliding member 22 with its end part being supported by the connector 26 fixed via a plate body 25 to the sliding member 22 and the plate body 27 for preventing small bulging. Thereafter, when the compressed air inside the air hose 24 is discharged, the sliding member 22 is moved downwards by the weights of the lower die 17, connection member 28, frame body 23 and sliding member 22, the upper die 19 is separated from the lower die 17 and the bending of metal plate is completed.
