Abstract
A valve apparatus is adapted to be at least partially inserted into an insertion hole of a counterpart member. The valve apparatus includes a housing and an O-ring. The housing is adapted to be inserted from an outside of the insertion hole into the insertion hole. The housing and the insertion hole define an annular gap therebetween. The O-ring seals the annular gap. The housing includes a substantially cylindrical base metallic member inserted into the insertion hole and an outer resin member. The outer resin member is fixed to the base metallic member, and at least partially defines an outer circumferential periphery of the housing. The base metallic member defines a bottom surface of a groove that supports the O-ring. The bottom surface of the groove is exposed circumferentially throughout from the outer resin member. The outer resin member defines a wall that restricts the O-ring from axially moving.
