  "textContent": "Provided is a high-pressure fuel supply pump capable of reducing a manufacturing cost of a part for holding a metal damper. The high-pressure fuel supply pump includes a pump body having a pressurizing chamber therein, a damper cover forming a damper chamber together with the pump body on the upstream side of the pressurizing chamber , a metal damper that is disposed in the damper cover and formed by laminating two metal diaphragms, and a first holding member that is disposed in the damper chamber and presses and holds the metal damper from one side. The first holding member includes a first regulation portion that regulates the radial movement of the metal damper , and a second regulation portion that regulates the radial movement of the first holding member in the damper chamber . At a position of the second regulation portion, a flow path is formed which allows the fuel in the damper chamber to circulate to both surfaces of the metal damper",
