Variable valve operating device for engine

Abstract

To provide a variable valve operating device that can swiftly adjust a valve timing of an engine, the variable valve operating device is for adjusting a valve lift and the valve timing of the engine. The variable valve operating device includes a rocking cam 27 which is rocked by cams 21 provided on a rotatable cam shaft 19, a rocking cam support member 25 that rockably supports the rocking cam 27, a valve 5 which is opened and closed by a rocking motion of the rocking cam 27, a rocking position changing unit 35 that moves the rocking cam support member 25 to change a lever ratio of the rocking cam 27 and that changes a rocking position of the rocking cam 27, and a lock unit 37 that can fix the rocking cam support member 25 so as not to move during a valve-opening period of the valve 5. The lock unit 37 includes a support base 23 that movably supports the rocking cam support member 25, and a push-link 43 which is rocked by an actuator 39. When a tip end of the push-link 43 abuts against the rocking cam support member 25, the push-link 43 pushes the rocking cam support member 25 toward the support base 23.
