Abstract
An axle driving apparatus housing therein a hydrostatic transmission and axles driven thereby a cooling fan which is provided on a power input shaft of the hydrostatic transmission. A cavity-like through opening is formed in a portion of the housing between the hydrostatic transmission and the axles. The peripheral wall of the opening is formed with a plurality of cooling fins. The cooling fan is rotated by the power input shaft to create wind to cool heat generated in the housing.
