を特徴とするフューエルポンプ。A rotor housing that houses a power button inside the cylindrical case defines a fuel suction side space and a fuel discharge side space, and a rotor that is rotationally driven by a motor installed in the case creates space between the rotor and the inner wall of the rotor housing. In a fuel pump configured such that a pump chamber formed in a chamber changes in volume and discharges fuel sucked from a suction side space into a discharge side space, the suction side space and the discharge side space are communicated with the rotor housing wall. A fuel pump comprising a fuel damper formed with a hole, a piston slidably inserted into the hole, and a spring that biases the piston in the direction of the discharge side space.
