Abstract
A lift and operating angle varying mechanism is arranged to vary an intake valve operation angle and an intake valve lift of the engine continuously by rotating a control shaft with an actuator disposed at an end of the control shaft which is rotatably supported by a plurality of bearings. A lubricating oil is supplied to the bearings so as to reduce nonuniformity in temperature distribution of the control shaft in the longitudinal direction.
