Abstract
A variable valve control apparatus which is capable of reducing the size of the entire apparatus. A rotary member is assembled with a timing pulley by a bolt so that it rotates together with the timing pulley. A cylinder head supports the rotary member rotatably but axially immovably. The rotary member supports an intake camshaft rotatably and axially movably. Even if the intake camshaft is axially moved and changed in rotational phase relative to the timing pulley as arc-shaped gears move axially, the rotational phase between an exhaust camshaft and the timing pulley does not change.
