The housing is formed with a guide groove at the outside in the radial direction from the O-ring and a discharge guide groove communicated with the guide groove and opening toward the outside in the radial direction. The cover is formed with a ring-shaped guide projection projecting out toward the guide groove at a position corresponding to the guide groove.
