を特徴とする分配型燃料噴射ポンプ。A roller holder that presses against the cam surface of the cam disk engaged with the drive shaft via a plurality of rollers arranged radially, and a roller holder that is housed in a cylinder that is integrally formed with the pump housing and communicates with the pump chamber pressure. The pump includes a piston that moves according to the pump chamber pressure, and a pin that has one end fixed to the rotor holder and the other end engaged with the piston, and adjusts the fuel injection timing by rotating the roller holder according to the pump chamber pressure. In the distribution type fuel injection pump, the cylinder is arranged parallel to the drive shaft, a cam surface is notched in the side surface of the piston along the axial direction, and a roller is attached to the other end of the pin. A distribution type fuel injection pump characterized in that the roller holder is brought into contact with the cam surface of the piston via the roller, and the roller holder is rotated in accordance with the movement of the piston.
