CONSTITUTION: A piston reciprocates in the compressed space of a cylinder. An opening and closing embodiment(60) blocks the compressed space and gas is sucked into the compressed space when the piston moves in a downward direction. When the piston moves in an upward direction, gas is compressed and vented from the compressed space by opening the space with the movement of the embodiment. An elastic supporting unit(62) is bent in this state. The opening and closing process is repeated in a state of hanging the elastic supporting unit on a hanging unit(51).
