Claims

[Claims for Utility Model Registration] (1) A differential case, a transaxle case surrounding the differential case, a bearing supporting the differential case in the transaxle case, and a transaxle case that supports the differential case. In a differential device comprising an oil seal for sealing oil in an axle case, two adjacent chambers are provided in the transaxle case, and the first chamber of the two chambers is a differential device. A lubrication circuit for the bearing and the oil seal is formed by directly communicating with a chamber in which the case is inserted and a chamber sandwiched between the oil seal and the bearing, and a second chamber communicates with the chamber forming the lubrication circuit and the outside to form a breather circuit. A breather mechanism for a differential device characterized by forming: (2) The differential assembly according to claim 1 of the utility model registration claim, characterized in that the transaxle case is composed of two parts, and the first and second chambers are formed on both sides of the mating surfaces thereof. Breather mechanism of the seal device. (3) A communication hole with the chamber into which the differential case enters is formed in one of the two parts of the transaxle case, and a partition wall is provided on the same side as the hole to further divide one side of the first chamber into two. A breather mechanism for a differential device according to claim 2, characterized in that: (4) A breather for a differential device according to claim 3 of the utility model registration, characterized in that the communication hole between the second chamber and the first chamber is provided on the same side as the first partition wall. mechanism.
