Abstract
A liquid remaining-amount detecting system includes a displacement transmitting part for transmitting displacement of a float to a rotation-angle sensor and including a bracket mounted to the bottom of a tank, an arm having a base end mounted to the bracket and a front end mounted to the float, and a link mechanism for coupling the rotation-angle sensor and the base end of the arm. The link mechanism serves to cancel displacement of the float resulting from vertical displacement of the bottom of the tank.
