Abstract
A vane rotor includes a laminated portion and seal portions. The laminated portion includes a plurality of metal plates, which are stacked in an axial direction. The seal portions are placed on two axially opposite sides of each of an advancing port, a retarding port, and a supply port. Each seal portion is configured into an annular form to extend along an outer peripheral surface of a sleeve in a circumferential direction and is engaged with the laminated portion to limit deformation of the seal portion toward a radially outer side. The seal portion is made of a material that has a thermal expansion coefficient, which is larger than a thermal expansion coefficient of a material of each metal plate.
