Abstract

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.

First claim

What is claimed is:

1. A valve timing control device, comprising:
a drive side rotating member that rotates in synchronization with an engine crankshaft;
a driven side rotating member, disposed so as to be rotatable relative to the drive side rotating member on the same axis as the drive side rotating member, that rotates together with a camshaft that opens and closes at least one of an inlet valve and exhaust valve of an engine; and
a locking mechanism that locks a relative r…
