Abstract
A vaporized fuel processing apparatus has a canister loaded with an adsorbent capable of adsorbing vaporized fuel generated in a fuel tank, a closing valve provided a vapor path connecting the canister and the fuel tank and having a valve seat and a valve movable portion such that a distance between the valve seat and the valve movable portion is stroke amount, a pressure sensor configured to detect inner pressure of the fuel tank, and an electric control unit. The electric control unit is configured to perform abnormal state depressurization control of the fuel tank, in a state that the pressure sensor cannot detect the inner pressure of the fuel tank, by setting the stroke amount of the closing valve at a fail-safe value in which the closing valve is closed, and then changing the stroke amount in a valve opening direction of the closing valve from the fail-safe value.
