Abstract (en)
[origin: EP4137694A1] Provided is a high-pressure fuel supply pump capable of improving strength of a flange without increasing a plate thickness. A flange 13 includes a step portion 13b1 (first step portion), a step portion 13b2 (second step portion), and a flat portion 13e1 (first flat portion). The step portion 13b1 protrudes in a direction away from a fuel pump attachment portion 90 on an outer periphery of the flange 13. The step portion 13b2 protrudes in a direction away from the fuel pump attachment portion 90 on the outer periphery of the flange 13, and faces the step portion 13b1 with the pump body 1 interposed therebetween. The flat portion 13e1 (first flat portion) is located between the step portion 13b1 and the step portion 13b2, and is flat from the pump body 1 to a first end of the flange 13.
