With vertical movement of a valve in an engine, a suspending member which suspends from a retainer engaged in the valve goes up and down with respect to a standing member on a cylinder head. A projection provided on the suspending member slides on inclined guide surfaces of the standing member, thereby attaining relative rotation of the suspending member forcibly with respect to the standing member, so that the valve is rotated on its axis.
