Claims

[Claims for Utility Model Registration] A common utility vehicle comprising a motor and a fuel pump coaxially disposed in the same casing, the rotor of the motor and the rotor of the fuel pump passing through the inside of the casing in the axial direction. A fuel pump device with a built-in motor rotatably supported on a fixed shaft, wherein the fixed shaft is press-fitted and fixed at one end into a hole bored in the casing, and at the other end. A fuel pump device with a built-in motor, characterized in that the fuel pump device is fixed by light press-fitting to a bearing made of a synthetic resin material fixed in the casing.
