Abstract:
Provided is a high-pressure fuel supply pump capable of fixing a cylinder to a pump body with excellent sealability in a simple structure even at a high fuel pressure. A high-pressure fuel supply pump including a pump body in which a pressurizing chamber is formed, and a cylinder inserted into a hole formed in the pump body and formed in a cylindrical shape, the high-pressure fuel supply pump including: a protrusion disposed at an end portion of the pump body opposite to the pressurizing chamber, formed from an outer peripheral side to an inner peripheral side with respect to an inner peripheral surface opposite to an outer peripheral surface of the cylinder, and protruding toward the cylinder, wherein the protrusion is formed so as to protrude to a side opposite to the pressurizing chamber with respect to a flat portion of the end portion of the pump body, and the protrusion is formed so as to support the cylinder from a side opposite to the pressurizing chamber.

Claim (Index 12):
A method of manufacturing a high-pressure fuel supply pump, wherein a cylinder is fitted into a cylinder fitting hole having a cylinder fitting hole bottom surface of a pump body, and a convex portion provided in advance at a peripheral portion of an inlet of the cylinder fitting hole of the pump body is compressively deformed in a cylinder insertion direction by a part of an end surface of a punch, such that the convex portion is plastically deformed toward an inner peripheral side, and plastic bonding is performed so as to cover a cylinder shoulder portion and a cylinder side surface of the cylinder while being pressure-bonded thereto.
