There is provided a breather capable of performing pressure regulation in a case by surely recovering liquid in a case without draining the same and performing only exhaust to the outside even when the pressure in the case rises rapidly. To attain this, a breather for regulating the internal pressure in a case by performing exhaust to the outside when the internal pressure in the case exceeds a predetermined pressure thereby reducing the internal pressure, includes an exhaust passage leading from the inside of the case to the outside; a liquid recovering passage for recovering the liquid drained from the inside of the case to the inside of the case; and discharge valve means which opens when the internal pressure of the case exceeds a predetermined one wherein the fluid recovery passage is provided on the atmosphere side beyond the discharge valve means, and recovery valve means is provided in the fluid recovery passage.
