Abstract:
Provided is a valve device by which it is possible to suppress a striking noise that occurs when a float valve descends, and for which the float valve is less likely to lift. This valve device (10) includes: a housing (15) that has a peripheral wall (55), a bottom wall (53), and a partition wall (21); and float valves (80, 85) that are accommodated inside a valve chamber so as to be liftable and that open and close an opening section. A slit (60) extends continuously from the peripheral wall (55) to the bottom wall (53), forming an elastic piece (66) that can be flexibly deformed via the slit (60). The elastic piece (66) has a free end section on the bottom wall (53) side thereof, and a float valve support that supports the float valve (85) is provided to the free end section.
