  "textContent": "A housing-includes a pressurizing chamber. A plunger is moved to increase and decrease a volume of the pressurizing chamber, so that the plunger can pressurize the fuel in the pressurizing chamber. A fuel chamber forming portion is placed on a radially outer side of the plunger and forms a fuel chamber that is communicated with the pressurizing chamber. A pulsation damper is placed in an inside of the fuel chamber and is operable to reduce pressure pulsation of the fuel in the fuel chamber. Fixable portions are placed on a radially outer side of the plunger while each of the fixable portions includes a receiving through-hole. The fixable portions are fixed to an engine with bolts, which are provided to correspond with the receiving through-holes, respectively. The fuel chamber forming portion is displaced from axes of the receiving through-holes.",
