A breather structure for a final reduction gear equipped with a differential, which can prevent a cost increase, improve quietness and durability, and prevent oil leakage to the outside even though the differential rotates at an increased rotation frequency is described. The breather structure is provided with a final reduction gear, in which an upper part of a housing is made into a breather chamber, which is communicated with an outside via a breather pipe, and a differential is rotatably stored in a housing. A plurality of oil stop ribs are provided, extending toward the differential, on an inner circumferential surface of the housing, to prevent oil having been scooped by the differential from flowing into the breather chamber. The oil stop ribs are provided at irregular intervals. |
