Claims

[Scope of utility model registration request]

A main chamber and a sub-chamber are formed in the tank body, and a feed pipe for sending fuel to the outside of the tank body and a return pipe for returning surplus fuel from the outside of the tank body are disposed in the main chamber, and an end portion of the return pipe is provided. is provided with a jet pump that generates negative pressure as the surplus fuel is jetted out, and the jet pump has an opening at one end located near the bottom wall of the sub-chamber, and uses the negative pressure to pump the fuel in the sub-chamber. In a fuel transfer device for a fuel tank in which a transfer pipe for suctioning and transferring to the main chamber is connected, the transfer pipe is provided with a horizontally extending portion extending substantially horizontally, and the horizontally extending portion includes: A fuel transfer device for a fuel tank, comprising a backflow prevention valve that allows fuel to be transferred from the auxiliary chamber side to the main chamber side and prevents fuel from returning from the main chamber side to the auxiliary chamber side.
