The present invention provides a pressing device for bending, in which a pipe is held between a bending die having a shape corresponding to a shape of bending and a clamping die revolvable around the bending die, and, when the pipe is bent by revolving the clamping die around the bending die, an axial compression force is applied to the pipe. The pressing device for bending includes a movable table arranged movable in an axial direction of the pipe, a first cylinder provided to the movable table and able to press a rear end of the pipe, and a second cylinder provided to the movable table and able to press a fixed side in a direction opposite to a direction in which the first cylinder presses the pipe. |
