Abstract
A valve timing control apparatus includes: a rear plate; a housing fixed to the rear plate; and a vane rotor which is able to rotate relative to the housing. The vane rotor includes a rotor and a vane extending from the rotor outward in a radial direction to divide an oil pressure chamber of the housing into an advance chamber and a retard chamber. The vane has an axial end surface adjacent to the rear plate and a radially outer surface. A first chamfer part is defined at a connection between the axial end surface and the radially outer surface of the vane so as to reduce a surface pressure applied from the rear plate to the vane.
