Abstract:
Provided is a valve device including a float (F) and a case (H) accommodating the float (F) therein, the valve device constituting part of a flow channel of a fuel tank (T). The float (F) includes a float main body (2) and a valve body (1) provided to an upper part of the float main body (2) so as to be capable of a tilting motion. The valve body (1) includes a seal portion (1a) that blocks a valve port (5a) formed inside the case (H) when the float (F) rises, a hooking portion (1b) that is hooked onto part of the float main body (2) and acts as the center of the tilting motion, and an abutting portion (1j') that protrudes from the rear side of the seal portion (1a). The valve device is configured such that the valve body (1) is caused to move in a horizontal direction as a result of the abutting portion (1j') abutting an abutted portion (2j) of the float main body (2) due to the tilting motion.
