Abstract
Provided is an actuator of a link mechanism for an internal combustion engine, in which a speed reducer is sufficiently lubricated. The actuator includes an oil passage formed in a control shaft for changing the posture of a control link and configured to feed lubricant oil to the speed reducer; and an open portion which opens to face the speed reducer in one end side located on the speed reducer side, and which is in communication with the oil passage in the other end side. An inner diameter of the one end side of the open portion is larger than an outer diameter of one end side of the oil passage.
