The housing includes a first intake port to introduce an air from outside. The strut cover has a discharge hole at a rear edge portion thereof. The turbine ventilation structure includes a first ventilation passage extending from the first intake port through the hollow portion, then extending from an inner end portion of the strut through between the strut and the strut cover, and the discharge hole, into the exhaust passage.
