Abstract

A pulsation damper for a fuel pump having a pump body in which a fuel passage is defined includes: a diaphragm that is elastically deformed in a predetermined direction by receiving a pressure of fuel; a casing part including a housing chamber that houses the diaphragm; and an attachment to be attached to the pump body. The attachment includes a communication passage that makes the housing chamber to communicate with the fuel passage. The attachment has a length in a perpendicular direction perpendicular to the predetermined direction, and the length of the attachment is smaller than a length of the casing part in the perpendicular direction.
