PURPOSE: To securely and easily suit a fuel injection amount to an operation temperature of an internal combustion engine by enabling a stopper to carry out position adjustment toward a stroke direction of a pump piston.
CONSTITUTION: When a membrane holding plate 22a for holding a membrane 22 is returned to a home position determined by a stopper 40, fuel is sucked into a pump chamber 18. Particularly, the stopper 40 is adapted to be capable of position adjustment toward a stroke direction of a pump piston 25 depending on a temperature. Therefore, a backstroke of the pump piston 25 is adjusted depending on the temperature. Thus, a quantity of the fuel sucked is varied at every backstroke depending on the temperature, and therefore the position adjustment can be carried out to reduce the quantity of fuel injection.
