Abstract
A valve operating device for an engine is provided. The device includes a cam element formed with an end face cam in one end thereof, and a control member driven by an actuator to project to an actuated position at which the control member is projected to engage with the end face cam so as to move the cam element in one of the axial directions, and retreat to a non-actuated position at which the control member is retreated from the actuated position. The cam element has a slope inclining in a circumferential direction of the cam element and for, when the control member is at the actuated position, sliding in contact with a contact part provided at the control member so as to forcibly move the control member back to the non-actuated position after the movement of the cam element via the end face cam is finished.
