Claims

[Scope of utility model registration request]

A valve housing is coupled to the carburetor body to define a valve chamber communicating with the float chamber between the carburetor body, and a first valve port is provided in the carburetor body facing the valve chamber and communicates with the intake passage. A second valve port is provided in the valve housing facing the valve chamber and coaxially opposed to the first valve port. A valve body is housed in the valve chamber and communicates with the second valve port to alternately open and close the second valve port. The valve body is fixed to the tip of a valve shaft which is movably supported by a bearing part in the middle part in a working chamber provided in the valve housing and which movably passes through the second valve port. In the air vent switching valve of the carburetor, the valve housing is formed of synthetic resin, and the bearing part is formed of a synthetic resin, and a passage opening into the working chamber is bored at the side of the valve so as to be connected to the canister. A vaporizer characterized in that the ribs are integrally provided in a cylindrical shape at the tips of a plurality of ribs protruding from the inner surface of the valve housing on the side opposite to the bearing part, and each rib and the bearing part are integrally molded with the valve housing. air vent switching valve for the device.
