PROBLEM TO BE SOLVED: To improve pumping efficiency and durability by preventing fuel leakage from a pump body attaching portion to a casing without being influenced by fastening at the time of attachment of a high pressure damper to the casing, and improving sealability between the plates of the casing and the high pressure fuel supply pump. SOLUTION: This pump, being arranged on a casing 2, has a pump body 24 provided with a piston 13 and a sleeve 9 in which the piston 13 is reciprocated, and a high pressure damper 35 arranged on the pump body 24 in a casing 2 on the side of a discharge passage 4. The pump body 24 and the high pressure damper 35 are coaxially arranged on the casing 2. |
