Abstract

PURPOSE: To make possible the reduction in the size of a vent valve by inserting into a vent hole a tubular member formed by a material harder than that of a resilient valve seat to prevent contraction of the diameter of the vent hole.
CONSTITUTION: A tubularmember 11 made of a material harder than that of a resilient valve seat 10 and having a vent hole d of a fixed diameter is fitted in a hole f formed on the resilient valve seat 10 along the entire length of the hole f. In the press holding state, a float valve 4 is pressed against the resilient valve seat 10 so that part of the resilient valve 10 is deformed to be pushed out from the lower end of a valve seat receiving member 9, while the diameter of the vent hole f of the resilient valve seat 10 remains unchanged in approximately a fixed diameter. Therefor, the size of the vent valve can be reduced.
