のバルブタイミング制御装置。 A cylindrical gear consisting of a plurality of gear structures in which at least one of the teeth provided on the inner and outer circumferences is a helical tooth and whose tooth traces are slightly shifted from each other is installed between the timing pulley and the camshaft. The rotation of the timing pulley is transmitted to the camshaft by meshing with the timing pulley, and the gear is moved in the axial direction of the camshaft by a gear drive mechanism to rotate the camshaft relative to the timing pulley, thereby controlling the intake and exhaust valves. A valve timing control device for controlling opening/closing timing of an internal combustion engine, characterized in that a spring member is interposed between the timing pulley and the camshaft to bias the timing pulley in the axial direction of the camshaft. Device.
