Valve timing control apparatus for internal combustion engine

A valve timing control apparatus for an internal combustion engine, the valve timing control apparatus comprising:

• a drive rotation member including a cylindrical wall to which a rotational force from a crank shaft is transmitted through teeth portions of an outer circumference, and which includes an opening opened on an one axial end side, and a bottom wall which is integrally provided on the other axial end side of the cylindrical wall, and which includes a through hole formed at a center;
• a housing which has a cylindrical shape, which is received within the drive rotation member, which includes one end opening closed by the bottom wall, and a plurality of shoes protruding from an inner circumference surface, and which includes a plurality of hydraulic chambers formed by the plurality of shoes;
• a vane rotor which is received within the housing to be rotated relative to the housing, which includes a rotor portion fixed at one end portion of a cam shaft, and vanes provided from an outer circumference surface of the rotor portion in radial directions, and which separates the hydraulic chambers into a retard angle hydraulic chamber and an advance angle hydraulic chamber, with the shoes;
• and
• a front plate which closes the other end opening of the housing, and which is connected to the housing and the drive rotation member from an axial direction,
• the drive rotation member including a positioning mechanism including a guide portion which is formed on an inner circumference surface of the cylindrical wall, and which has an inclined shape whose an inside diameter is decreased from the one axial end side to the other axial end side, a mounting protrusion portion which is formed on the other end side of the guide portion, and on which an outer circumference surface of the housing is mounted to be positioned.
