  • Patent number: 11230271
    Abstract: Of moving directions of a piston, the direction in which high-pressure air is delivered is a delivery direction, and the direction in the opposite direction from the delivery direction is a force accumulation direction. The piston is moved in the force accumulation direction by the moving mechanism, and moved in the delivery direction by the biasing force of the biasing spring in response to the release of the moving force exerted by the moving mechanism. The cylinder is provided with: a piston supporting portion that supports the piston; and a connection protrusion that has a delivery path for delivering the high-pressure air to the nozzle. The inner surface of an end of the piston supporting portion in the delivery direction is formed as a closed surface. The delivery path is located further toward the force accumulation direction than the closed surface is.
