Claims

[Scope of utility model registration request]

A rotary joint is provided in which a motor is provided inside the casing, a flow path is provided that passes through the rotor of the motor and passes through the shaft supported by a bearing from one end to the other end, and the rotary joint is attached to one end of the shaft protruding from one of the bearings. A connection port is provided on the outside of the casing to communicate with the flow path of the shaft through the inlet, and the other end of the shaft protruding from the other bearing is provided with a drill stop to which a drilling drill having an axial through hole is removably attached. A drilling machine for concrete structures, which is provided with a mounting part, and a drilling drill is fixed to the drill mounting part, so that a flow path of the shaft and a through hole of the drilling drill communicate with each other.
