A cooling device includes: a cooling fan; a shroud provided at an outer circumferential side of the cooling fan; an inner circumferential wall provided on the shroud and adjacent to the outer circumference of the cooling fan; and an outer circumferential wall provided to surround the inner circumferential wall. An air-flow-direction downstream side end of the outer circumferential wall is positioned at a further downstream position in an air flow direction than an air-flow-direction downstream side end of the inner circumferential wall. An air-flow-direction downstream side end of the cooling fan is positioned at a further downstream position than the air-flow-direction downstream side end of the inner circumferential wall. A ratio between a length of the outer circumferential wall and a length of the inner circumferential wall in the air flow direction is 1.07 or more and 1.81 or less, and a width between the outer circumferential wall and the inner circumferential wall is 15 mm or more and 55 mm or less.
