Abstract
A detent mechanism that increases a holding force for a valve member having two switch positions includes a ring shaped housing groove and an annular elevated portion. A ring shaped detent member made of a material having rubber elasticity is housed in the housing groove. The housing groove includes right and left groove side walls which extend in parallel to each other, and a groove bottom wall. The detent member includes right and left side walls which face the groove side walls of the housing groove and a protruding portion which extends from the housing groove. A locking section which elastically locks the protruding portion of the detent member in the two switch positions is formed at both axial ends of the elevated portion.
