In a housing body of an engine valve timing control apparatus, a vane rotor includes a vane, wherein the vane and shoes of the housing body define advance and retard chambers. The housing body is formed with a pulley adapted to winding of a belt, and formed with first bolt holes extending axially through the housing body, and formed with a sealing recess at an open axial end. A plate is fixedly inserted in the sealing recess, and formed with second bolt holes facing the first bolt holes. An annular first sealing ring is arranged between an inside periphery of the sealing recess and an outside periphery of the plate. An annular second sealing ring is arranged between the plate and an axial end surface of one of the shoes, wherein the second sealing ring extends circumferentially around one of the second bolt holes.
