发明名称 FUEL SUPPLY SYSTEM
摘要 A seal is fit between a cylindrical connector support which is protruded on an upper end face of a cylindrical barrel part of an electrically-powered high pressure pump embedded in a housing and from which a power connector is exposed and an inner peripheral surface of a hollow part formed in a top face of a lid body such that the seal is flush with a top face of the hollow part. A flange having an outer shape which is the same as an inner shape of the hollow part is protrudingly provided at a predetermined height position on a circumference of the connector support such that a lower surface of the flange is disposed flush with a top face of the hollow part.
