A fuel supply device has a cover member which is attached to an opening of a fuel tank, a pump unit provided with a pump, and a connecting portion for connecting the cover member and the pump unit. The fuel supply device has a connecting shaft which is formed on either one of the connecting portion or the pump unit, and a connecting hole which is formed on the other. The fuel supply device has a guide mechanism which can guide the pump unit. The guide mechanism includes a first guide portion formed at the connecting portion and a second guide portion formed at the pump unit. One of the first guide portion or the second guide portion includes a protruding portion which protrudes in a position spaced apart from the connecting shaft. The other guide portion is formed to restrict a movable range of the protruding portion.

Fuel supply devices

A fuel supply device includes a cover member which is attached to an opening of a fuel tank, a pump unit comprising a pump, and a connecting portion for connecting the cover member and the pump unit. The pump unit is connected to the connecting portion so as to be relatively movable to the cover member. When the fuel supply device is attached to the fuel tank, an engagement portion provided at a lower portion of the pump unit abuts the connecting portion such that via the engagement portion the connecting portion presses the pump unit against the fuel tank.

A fuel supply device has a cover member which is attached to an opening portion of a fuel tank and a pump unit comprising a pump. The cover member and pump unit are connected via a connecting portion where the pump unit is rotatably connected to the connecting portion. Further, the fuel supply device includes a fuel residual amount detection device which is attached to the pump unit and configured to detect the residual amount of fuel. The fuel residual amount detection device includes a gauge main body to which electric wirings are connected, an arm portion which is movably mounted relative to the gauge main body and a float which is attached to a leading end of the arm portion. The float is positioned above a lower terminal end of the base portion when the cover member is held and lifted while the pump unit rotates with respect to the connecting portion.

A fuel supply device includes a cover member attached to an opening of a fuel tank, a pump unit including a pump, and a connecting portion which connects the cover member and the pump unit. The pump unit is connected so as to be relatively movable with respect to the connecting portion when a connecting shaft which is formed as part of one of the connecting portion or the pump unit, is inserted into the connecting hole formed as part of the other of the two. The connecting hole has an elongated hole portion that allows the connecting shaft to move in the upward and downward directions, and allows the pump unit to be relatively movable with respect to the connecting portion. The pump unit includes an engagement portion abutting a lower terminal end of the connecting portion when the fuel supply device is attached to the fuel tank.
