Valve timing control device, locking jig for valve timing control device, and manufacturing method of valve timing control device

摘要

A valve timing control device (10) that controls a valve timing of a valve opened and closed by a camshaft (91) using torque transmitted from a crankshaft (90) in an internal combustion engine, the valve timing control device (10) comprising: a first housing (29) which rotates with the crankshaft (90) or the camshaft (91); a second housing (28) which is fixed to the first housing (29); a driven rotor (26) which is inside a drive rotor (25) defined by the first housing (29) and the second housing (28) fixed to an end portion of the other of the crankshaft (90) or the camshaft (91), a rotary actuator (11) arranged on an extension of an axial direction of the driven rotor (26);a deceleration mechanism (27) which decelerates relative rotation of the orbiting actuator (11) to the drive rotor (25) and into a e converts relative rotation of the driven rotor (26) to the drive rotor (25); andan engaging member (33) which, before assembling the valve timing control device (10) to the internal combustion engine, is engaged with a locking jig (60, 70) which controls relative rotation between the drive rotor (25) and an input rotor (39) of the delay mechanism ( 27) locked, wherein the engaging part (33) is arranged on a radial inner side in comparison with an insertion part (23) of the rotary actuator (11) which is inserted into a hole (93) of a cover member (92) of the internal combustion engine, the Engaging member (33) is part of a fixing member (31) fixing the first housing (29) and the second housing (28), the deceleration mechanism (27) has a ring gear (37) integral with the second housing (28). is formed, and the fixing member (31) is arranged in a circumferential direction at a same position as a tooth tip part of the ring gear (37).
