An oil control valve mounting arrangement includes a resin coverwith a metal cylindrical bodyinsert-molded therein, a valve sleevehoused within the cylindrical body, and a spoolinserted in the valve sleeve In at least at one end portionof the cylindrical bodyin the axial direction of the valve sleeve, the coverincludes an engaging portionengageable with an interior-facing faceof the cylindrical bodyfacing the radially inner side of the valve sleeveat an end of the cylindrical bodyin the axis direction of the valve sleeveso as to restrict displacement of the coveraway from the cylindrical bodyin the radial direction of the valve sleeve

Oil control valve mounting arrangement

Provided is a valve timing control device, including a drive side rotating member, a driven side rotating member, and a locking mechanism, in which the locking mechanism includes a regulating body, and n stepped portions with which the regulating body engages, the relative rotation phase is regulated in steps from a most retarded phase or most advanced phase until reaching the lock phase, and the positional relationship between the stepped portions and regulating body is set so that, among relative rotations of from a first relative rotation of from the most retarded phase or most advanced phase to a first relative rotation phase regulated by a first stepped portion to a last relative rotation to a last relative rotation, a first predetermined relative rotation other than the last relative rotation is the smallest.

Valve timing control device

A variable valve timing control apparatus includes a driving side rotation member, a driven side rotation member positioned coaxially with a rotational axis of the driving side rotation member, at least one plate, a plurality of partition portions forming a fluid chamber between the partition portions, a vane portion being fitted to the fluid chamber to relatively rotate the driving side rotation member and the driven side rotation member within a movable range thereof, a restriction mechanism for restricting a relative rotational phase, a fastening member fixing the plate and the partition portion of the driving side rotation member, and a reinforcement member engaged with the partition portion including a contact surface among the partition portions, the contact surface being configured to receive a contact of the vane portion when the relative rotational phase is either at a most retarded angle phase or a most advanced angle phase.
