Abstract
A socket portion () capable of mounting either of a high pressure exclusive plug and a normal pressure exclusive plug is formed at one end of a coupler (). In the coupler (), an opening/closing valve () for opening and closing a flow path of a compressed air is provided, and a pressure reducing valve for reducing an air pressure to a predetermined pressure value proximate to substantially an upper limit value of an operating pressure region of a normal pressure tool by controlling the opening/closing valve () is formed. Thereby, when the normal pressure exclusive plug (P) is mounted, air the pressure of which is reduced by the pressure reducing valve is supplied to the normal pressure exclusive plug (P).
