A tappet support member includes at least two slide surfaces and at least two press-fitting projections. The at least two slide surfaces, are planar and extend in an axial direction of a plunger. The at least two slide surfaces are substantially parallel to each other and are opposed to each other, and a shoe of a tappet is axially reciprocatably supported by the at least two slide surfaces. Each of the at least two press-fitting projections projects from a corresponding side of the tappet support member that is opposite from a corresponding one of the at least two slide surfaces, and each of the at least two press-fitting projections is press-fitted into a pump housing, which is stationary relative to the tappet.
