CONSTITUTION: An air pressure spraying means comprises an inlet hole (51), a tube connection (52), and an air pressure spraying nozzle part (53). The inlet hole is punched in one side of a housing part (20). The tube connection is connected to one side of the inlet hole. The tube connection is inserted by an air pressure tube (T). The air pressure spraying nozzle part is connected to the other side of the inlet hole. The air pressure spraying nozzle part sprays the air pressure flowed in from the air pressure tube to the inside of a cover unit (40). |
