Abstract (en)
The device has a rotor component (2) assembled to a housing component (3). A stopper is formed on a convex portion to define a relative rotation between the components. A receiving hole (22) restricts the rotation by a lock plate (80). The plate is in contact with an inner peripheral face of the hole on advanced and retarded angle sides between opening and bottom portions (22a, 22d) of the hole when the rotation is restricted.
A variable valve timing control device (1) includes a housing member (3), a rotor member (2) assembled to the housing member so as to be rotatable relative thereto and including vane portions (70) each forming an advanced angle chamber (R1) and a retarded angle chamber (R2) within the housing member (3), a stopper (33a,33b) formed on the convex portion for defining a relative rotation between the housing member (3) and the rotor member (2), a lock mechanism (22,88) for restricting the relative rotation by a lock member (80), and a fluid pressure circuit for controlling an operation oil to be supplied to or discharged from the advanced angle chamber (R1), the retarded angle chamber (R2), and the lock mechanism (22,80). When the relative rotation is restricted, the lock member (80) is in contact with an inner peripheral face of the receiving hole (22) on the advanced angle side and the retarded angle side between an opening portion (22a) and a bottom portion (22b) of the receiving hole (22). <IMAGE>
