This causes the end of the hose to be clamped between the projection and the tapered surface. Next, a pressure fluid such as pressurized air is supplied from the fluid supply device to the interface between the mandrel and the hose via the inner cylinder member. As a result, the entire hose is expanded in diameter and the state of close contact with the mandrel is released. Then, the first driving device is driven, and the inner cylinder member and the outer cylinder member move away from the mandrel while holding the hose. This causes the hose to be pulled out of the mandrel.
