Abstract

See full text

A valve device includes a float body and a valve body provided in an upper portion of the float body to obliquely move. The valve body includes a seal portion that closes a valve opening formed in a case when the float rises, an engaging portion serving as a linkage portion with respect to the float body, and an abutting portion that abuts on a vicinity of the valve opening when inclining obliquely. An area of the abutting portion in the horizontal direction is made smaller than that of the seal portion such that the abutting portion laterally protrudes from the seal portion.
