The invention provides an air breather. The air breather can prevent moisture from dipping a transfer case shell loaded in a vehicle. In a separated ventilation box (1) used for the ventilation in the transfer case shell (70), a separating wall part (51) divides an accepting part(11), through which air inflow passes, into two segments in the up and down directions, and a maze structure channel (47) which is divided into a maze shape by utilizing spacing walls(17) is formed in a lower-segment layer which is at the lower side of the separating wall part (51), so that the bottom(15) of the channel (47) is formed into a tilting shape which drops gradually, facing a water outlet, and accordingly, even on the condition that the air sucked from a breathing port contains much moisture and is vaporous, the separation of moisture can be promoted when the air passes the maze structure channel (47), and the separated moisture can be discharged externally efficiently. Therefore, the air containing less moisture can be suc
