A cooling device includes a cooler disposed inside a shell, an inlet nozzle that is configured to feed a fluid into the shell, an outlet nozzle that is configured to feed the fluid passing through the cooler so as to flow outward, and a guide member that is configured to change a flowing direction of the fluid. The guide member has a collision surface which spreads in an inclined direction inclined with respect to the flowing direction of the fluid fed into the shell from the inlet nozzle, and which collides with the fluid, and an uneven portion formed in at least a portion of a peripheral edge portion of the collision surface.

Provided is a seal device configured to prevent leakage of a fluid on an outer circumferential surface of a rotary shaft in a direction along an axis of the rotary shaft. The seal device includes an annular main body section disposed in a circumferential direction of the rotary shaft, and a plurality of at least two kinds of holes formed in an inner circumferential surface of the main body section opening and facing to the outer circumferential surface of the rotary shaft, and having different depths.
