Abstract

A differential includes a drive rotating body rotatable about a rotation axis, a planetary rotating body that is rotatable and is revolvable about the rotation axis, and a driven rotating body rotatable about the rotation axis. The planetary rotating body is made to mesh with each of the drive rotating body and the driven rotating body, so that a first speed reducer is constituted between the planetary rotating body and the drive rotating body and so that a second speed reducer is constituted between the planetary rotating body and the driven rotating body. The planetary rotating body is driven by an electric motor, and the drive rotating body is driven by a driving force from an engine. The intake camshaft is provided on the driven rotating body, and the exhaust camshaft is provided on the drive rotating body.
