摘要： A pipe joining structure adapted to join a pipe to a fluid passage of an equipment housing. An end portion of a pipe is bent by about 90 degrees to form a bend portion and a tip of the bend portion is fitted into an opening of the fluid passage. The pipe joining structure includes a stay fitted over the bend portion of the pipe, a tip of the pipe is formed with a flange, and an O-ring fitted between the stay and the flange of the pipe. The tip of the pipe is joined to the equipment housing by fixing the stay to the equipment housing.
