摘要： A supercharger is provided with: a housing; a rotary shaft that is supported inside the housing to be freely rotatable; a compressor wheel that is provided at one end in an axial direction of the rotary shaft; a cooling water supplying pipe and a cooling water discharging pipe that have a flange part at an end and are connected to the housing; and a lubricant supplying pipe that has a flange part at an end and is connected to the housing. The ends of the cooling water supplying pipe and the cooling water discharging pipe are inserted into a cooling water supplying flow path and a cooling water discharging flow path of the housing, respectively. The end of the lubricant supplying pipe is inserted into a first supplying flow path of the housing. The flange part presses the flange parts in an insertion direction and is fixed to the housing.
