Abstract
A fuel supply device includes a sub-tank, a pump unit, a jet pump, and a connection structure connected with the pump unit and the jet pump. The connection structure has a guide part that is provided to the pump unit and guides the pressurized fuel toward the bottom in an axial direction, a pressurizing part that is provided to the jet pump and is fitted to the guide part from a side of the bottom in an axially slidable manner, to which the pressurized fuel is guided from the guide part, a shock-absorbing member that has a low spring constant that is predetermined and mitigates an axial impact between the guide part and the pressurizing part, and a sealing member that has a high spring constant higher than the low spring constant of the shock-absorbing member and radially seals a space between the guide part and the pressurizing part.
