Abstract

In a high-pressure pump, a relief valve seat surrounds an opening of a relief valve passage of a valve seat main body in a first space. A relief valve member includes a relief valve main body and a relief valve seat portion. The relief valve main body has a rod shape. The relief valve seat portion is integrated with an end of the relief valve main body so as to be capable of contacting the relief valve seat. The relief valve member is provided in the first space so as to be reciprocable in an axial direction. A relief valve urging member urges the relief valve member toward the relief valve seat. A support portion includes a support main body that slidably supports an outer wall of the relief valve main body so as to guide a reciprocating movement of the relief valve member in the axial direction.
