Abstract
In an internal combustion engine, the movement of the cam on the camshaft is transmitted to each valve of each cylinder by way of a tappet member. The tappet member is held in a swinging member which can be swung about the camshaft. The swinging member is swung about the camshaft back and forth in the rotational direction of the camshaft by a control device according to the operating condition of the engine. When the swinging member is swung about the camshaft, the relative position of the tappet member to the cam at a given angular position of the camshaft is changed, whereby the valve timing of the valve associated with the tappet member is changed.
