A valve timing change device which changes an opening/closing timing of an intake valve or an exhaust valve driven by a cam shaft, the valve timing change device comprising: a housing rotor that rotates on an axis of the cam shaft; a vane rotor that demarcates an advance angle chamber and a delay angle chamber in cooperation with the housing rotor and rotates on the axis; a fastening bolt that fastens the vane rotor such that the vane rotor rotates integrally with the cam shaft, and has oil passages; and an advance angle oil passage that constitutes a ring-shaped groove communicating with the advance angle chamber and a delay angle oil passage that constitutes a ring-shaped groove communicating with the delay angle chamber, via oil passages which are open at intervals on an outer circumferential surface of the fastening bolt, wherein the vane rotor includes a rotor body which has a small-diameter inner circumferential portion coming into tight contact with the outer circumferential surface of the fastening bolt, and a large-diameter inner circumferential portion being formed to have a larger diameter than the small-diameter inner circumferential portion; and a rotor sleeve which is not in contact with the cam shaft, is fitted into the large-diameter inner circumferential portion, is in tight contact with the outer circumferential surface of the fastening bolt, and demarcates one of the advance angle oil passage and the delay angle oil passage in cooperation with the small-diameter inner circumferential portion; the valve timing change device being characterized in that the rotor sleeve includes a ring-shaped end surface which demarcates one of the advance angle oil passage and the delay angle oil passage in cooperation with the small-diameter inner circumferential portion, and a tubular portion which is press-fitted into the large-diameter inner circumferential portion and demarcates the other of the advance angle oil passage and the delay angle oil passage. a housing rotor that rotates on an axis of the cam shaft; a vane rotor that demarcates an advance angle chamber and a delay angle chamber in cooperation with the housing rotor and rotates on the axis; a fastening bolt that fastens the vane rotor such that the vane rotor rotates integrally with the cam shaft, and has oil passages; and an advance angle oil passage that constitutes a ring-shaped groove communicating with the advance angle chamber and a delay angle oil passage that constitutes a ring-shaped groove communicating with the delay angle chamber, via oil passages which are open at intervals on an outer circumferential surface of the fastening bolt, wherein the vane rotor includes a rotor body which has a small-diameter inner circumferential portion coming into tight contact with the outer circumferential surface of the fastening bolt, and a large-diameter inner circumferential portion being formed to have a larger diameter than the small-diameter inner circumferential portion; and a rotor sleeve which is not in contact with the cam shaft, is fitted into the large-diameter inner circumferential portion, is in tight contact with the outer circumferential surface of the fastening bolt, and demarcates one of the advance angle oil passage and the delay angle oil passage in cooperation with the small-diameter inner circumferential portion; the valve timing change device being characterized in that the rotor sleeve includes a ring-shaped end surface which demarcates one of the advance angle oil passage and the delay angle oil passage in cooperation with the small-diameter inner circumferential portion, and a tubular portion which is press-fitted into the large-diameter inner circumferential portion and demarcates the other of the advance angle oil passage and the delay angle oil passage.
