The invention discloses a rotational driving apparatus for cold testing an internal combustion engine to which a ring gear is attached. The rotational driving apparatus has a rotor that is rotatively driven about the rotation axis of the ring gear of an internal combustion engine that is in the testing position. A pivot arm is supported rotatably with respect to the rotor via a link pin. The front end portion of the pivot arm is provided with an engaging portion that can engage the ring gear through shifting to the inward side with respect to the radial direction. The pivot arm also has a portion that extends rearward of the link pin. When the rotor is rotated, this portion extending to the rear generates a torque in the direction in which the engaging portion is shifted so as to engage the ring gear. A link that extends at an angle that is nearly perpendicular to the rotation axis is joined to the rear end of the pivot arm. The other end of the link is joined to a reciprocating member that is shifted in the direction along the rotation axis by an actuator.
