ABSTRACT:
A variable valve operating device is provided that can swiftly adjust a valve timing of an engine and is for adjusting a valve lift and the valve timing of the engine. The variable valve operating device includes a rocking cam, a rocking cam support member, a valve, a rocking position changing unit, and a lock unit that can fix the rocking cam support member so as not to move during a valve-opening period of the valve. The lock unit includes a support base that movably supports the rocking cam support member, and a push-link which is rocked by an actuator. When a tip end of the push-link abuts against the rocking cam support member, the push-link pushes the rocking cam support member toward the support base.
