PROBLEM TO BE SOLVED: To provide a smooth engagement operation between an intermediate rotor and a movable guide part while allowing some degree of molding error. SOLUTION: A spiral groove 15 is formed in the intermediate rotor 18 inputting an external rotating operation force, and the movable guide part at the tip of a link 11 is engaged with the spiral groove 15 and the radial groove 8 of a drive ring 3. The base end of the link 11 is pivotally connected to the lever 9 of a driven shaft member 7, and the assembling angle of the drive ring 3 and the driven shaft member 7 is changed by the rotating operation of the rotor 18. In such a valve timing control device, An engagement pin 16 is rotatably and rockably housed in the housing hole 14 of the link 11, and a part of the movable guide part is constituted by the engagement pin 16. The head part 41 of the engagement pin 16 is spherically formed, and the head part 41 is engaged with the semi-circular sectional spiral groove 15. The molding error is absorbed by the rocking of the engagement pin 16. COPYRIGHT: (C)2004,JPO
