VALVE TIMING ADJUSTMENT SYSTEM AND MANUFACTURING METHOD OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a valve timing adjustment system capable of inhibiting misalignment between an axis of a solenoid cover and a rotation axis of a valve timing adjustment mechanism.SOLUTION: A valve timing adjustment system 1 includes: a solenoid 90 at one side of a valve timing adjustment mechanism 20 when viewed in a rotation axis direction of the valve timing adjustment mechanism 20. A cylindrical solenoid cover 91 enclosing an outer periphery of the solenoid 90 extends to the valve timing adjustment mechanism 20 side and slidably fits in a surface 271 at the radial inner side of a housing 21 included in the valve timing adjustment mechanism 20. The structure inhibits misalignment between the solenoid cover 91 and the valve timing adjustment mechanism 20 in a radial direction.SELECTED DRAWING: Figure 1
