ABSTRACT:
An air breather structure for oil seals in an automatic transmission having a final reduction device and an automatic transmission device. Each oil seal comprises a pair of sealing members with a space therebetween. A differential case for the final reduction device and an automatic transmission case are coupled at ends thereof interposing a gasket. Two rotating shafts extend across the gasket for transmitting an output of the automatic transmission to front and rear wheels of a vehicle for four-wheel driving. The oil seals are provided around the rotating shafts respectively. Both of the oil seals are located in the automatic transmission case and the space of each oil seal is communicated with the atmosphere through passages including cavities provided in both cases and an opening formed in the gasket and a hole formed in an upper portion of the differential case.
