Abstract: An evaporated fuel processing device includes a liquid level surface detection valve that detects a full-tank liquid level surface when refueling, and closes a canister communication hole; a fuel shutoff valve to close an evaporation hole when a liquid level surface becomes higher than the full-tank liquid level surface; and an outlet port communicating with a canister. A first communication path and a second communication path are formed in a folded back shape folded back at a first valve seat upper part in plan view. The first communication path enables communication between the first valve seat upper part and a second valve seat upper part, and the second communication path enables communication between the first valve seat upper part and the outlet port. This constitution reduces fuel liquid leakage from the outlet port.

Abstract: A fuel tank including a built-in component is provided. The built-in component includes: a carrier part being a rigid body including a plurality of engaging parts, and a plurality of struts each including an engageable part to be engaged with one of the engaging parts. The engageable part of the strut includes an upper contact surface and a lower contact surface, which are formed spaced apart from each other in a height direction. The engaging parts of the carrier part each includes a biasing part that, when the strut is engaged with the engaging part, enters a space between the upper contact surface and the lower contact surface and generates biasing forces in directions to move the upper contact surface and the lower contact surface away from each other.

Abstract: A fuel fill opening structure for a fuel tank includes a fuel filler pipe, a fuel fill opening, and a flow guide. The flow guide includes a main guide wall which partitions a fuel introduction region inside the fuel filler pipe into an upper space communicating with a tank main body side and a lower space communicating with the fuel fill opening side, and a partition wall provided to be continuous with the main guide wall and configured to close a space between an upper surface side of the main guide wall and an inner surface of the fuel filler pipe. The main guide wall includes a bent inclined part that is bent and inclined downward from a middle portion in running from the fuel fill opening side toward the tank main body side. The bent inclined part has a shape in which a width thereof becomes smaller when viewed from above as it inclines downward.
