Patent ID: 7520167

Claim:
A fuel level gauge comprising: a rotatable member; a stationary member for rotatably supporting the rotatable member; a float floating on a surface of fuel in a fuel tank; an arm member for connecting the float to the rotatable member so that changes in positions of the float are converted to rotation of the rotatable member; means, connected to the stationary member, for detecting rotational positions of the rotatable member to thereby detect a fuel level of the fuel in the fuel tank, the detecting means including a battery terminal, a ground terminal and a signal terminal; and means for electrically connecting the arm member to the ground terminal to ground electrostatic charges accumulated on the arm member, wherein: the electrically connecting means is an elongated metal member having a ring portion formed at one end thereof; the ground terminal includes a hole having a diameter larger than a diameter of the metal member; and the ring portion of the metal member is rotatably coupled to the arm member and the other end of the metal member is inserted into the hole of the ground terminal to be slidably connected thereto.
