A valve timing change device which changes an opening/closing timing of an intake valve or an exhaust valve driven by a cam shaft (S), the valve timing change device comprising: a housing rotor that rotates on an axis (L) of the cam shaft (S); 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 (L); a fastening bolt that fastens the vane rotor such that the vane rotor rotates integrally with the cam shaft (S), 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 (S), 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 (L) of the cam shaft (S); 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 (L); a fastening bolt that fastens the vane rotor such that the vane rotor rotates integrally with the cam shaft (S), 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 (S), 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 . <EOS>
