To provide an engine cooling device to improve cooling efficiency by suppression of leakage of cooling air from a tip clearance.

In the engine cooling device formed that a space between a fan rotated by an engine serving as a power source and a radiator is covered by a shroud having an opening for a fan, a cylindrical ring member to surround the fan is mounted on the outer edge part of a fan is mounted on the outer edge part of a fan, and a labyrinth groove to contain the edge part of an opening throughout a whole periphery is formed in the part, opposite to the opening, of the outer peripheral surface of the ring member.
