A cylindrical elastic sealing member is engaged with the coupling hole to seal the space between the flow control valve and the coupling hole. The elastic sealing member has an inner surface defining a mounting hole in which the fitting portion is fitted. A female thread is formed on the inner surface and is mated with the male thread of the fitting portion.
