There is no water leakage at the joint because it is sealed by a rubber ring.
Further, on the back side of the rubber ring receiving portion, the vertical dimension of the enlarged diameter receiving port is set to be substantially the same as the outer diameter of the short pipe, and
Since the horizontal dimension is set to be larger than the outer diameter of the short pipe, the vertical movement of the short pipe in the enlarged diameter receiving port is suppressed, and the horizontal movement is allowed.
