Abstract
A valve timing adjusting device includes an intake variable valve mechanism and an exhaust variable valve mechanism. The exhaust variable valve mechanism includes an exhaust electric driving portion and an exhaust phase shifting portion including an input shaft. The exhaust phase shifting portion is disposed in a rotation transmission path between an exhaust camshaft and a crankshaft and configured to shift a rotation phase of the exhaust camshaft. The input shaft rotates in a rotational direction opposite to a rotational direction of the crankshaft when advancing the rotation phase. A phase of the exhaust phase shifting portion is configured to be shifted to a most advanced angle phase when the exhaust electric driving portion is de-energized or fails and when the exhaust phase shifting portion receives a torque in a forward rotational direction.
