DEVICE FOR CONTROLLING VALVE OPENING/CLOSING TIMING

摘要

A technical object is to prevent oil from leaking out, to reduce axial dimensions, and to reduce the number of parts and the cost in a valve timing control apparatus.
The valve timing control apparatus comprises a rotor 2 linked to a camshaft 1 of an internal combustion engine; a drive member 30 which is linked to the drive shaft of the internal combustion engine and supports the rotor 2 in a relatively rotational manner; and a hydraulic chamber 35 which is partitioned by a vane 6 and is disposed between the rotor 2 and the drive member 30, wherein the drive member 30 comprises an outer rotor 31 forming the hydraulic chamber 35 together with the rotor 2; a housing member 3 including a front plate portion 32 joined to one axial end of the outer rotor 31 and a tubular portion 33 linked the front plate portion 32 and positioned on the outer radial side of the outer rotor 31; and a rear plate [member] 4 joined to the other axial end of the outer rotor 31 and to the housing member 3.
