Abstract:
A high-pressure fuel pump capable of reducing the number of components and decreasing the manufacturing cost by processing of a pump body is provided. The high-pressure fuel pump includes a metal damper, a pump body in which a damper housing that houses the metal damper is formed, a damper cover attached to the pump body, covering the damper housing, and holding the metal damper between the pump body and the damper cover, and a holding member fixed to the damper cover and holding the metal damper from a side opposite to the damper cover. The holding member is provided with an elastic portion that urges the pump body so that the metal damper is urged toward the damper cover.
