Abstract: A fuel supply device includes a pump unit, a lid unit and a strut linking unit. The pump unit is located on a bottom of a fuel tank for discharging fuel from the fuel tank to an outside thereof. The lid unit is attached to an upper wall of the fuel tank to close an opening formed in the upper wall. The lid unit has a fuel discharge port. The strut linking unit connects the lid unit to the pump unit. The strut linking unit includes an upper-side strut member, which is formed as an independent component from the lid unit. The strut linking unit includes a lower-side strut member, which is movably connected to the upper-side strut member in a vertical direction. The upper-side strut member is connected to the lid unit by a snap-fit connection. A connecting portion between the upper-side strut member and the lid unit has a stress concentration portion, which is preferentially damaged when an external force is applied to the strut linking unit.
