摘要： PROBLEM TO BE SOLVED: To prevent leakage of a lubricant from a breather part, and contrarily, suction of outside water via the breather part.
SOLUTION: A hollow part of a propeller shaft 12 and a sealed space 44 of a differential carrier 14 are communicated with each other via a breather passage 50 arranged in a drive pinion 24 and a rubber hose 52, while a rubber balloon 54 varying its volume according to a pressure is arranged in the hollow part of the propeller shaft 12. When air in the differential carrier 14 expands, the lubricant escapes from the breather passage 50 to the rubber balloon 54, and leakage of the lubricant from an oil seal 42 is prevented. When a pressure in the differential carrier 14 is lowered, the lubricant in the rubber balloon 54 is pushed back into the differential carrier 14, and poor lubrication due to shortage of an oil quantity is prevented while deterioration of rotary balance due to the lubricant in the propeller shaft 12 is prevented. In travel on a flooded road, poor lubrication due to suction of outside water into the differential carrier 14 is not caused.

摘要翻译：要解决的问题：为了防止润滑剂从通气部分泄漏，相反地，通过通气部分吸入外部水。解决方案：传动轴12的中空部分和差速器载体14的密封空间44经由布置在驱动小齿轮24和橡胶软管52中的通气通道50彼此连通，而橡胶气囊54 在传动轴12的中空部分设置有根据压力而变化的体积。当差速器载体14中的空气膨胀时，润滑剂从通气通道50逸出到橡胶球54，并且润滑剂从油中泄漏防止了密封件42。当差速器载体14中的压力降低时，橡胶球囊54中的润滑剂被推回到差速器载体14中，并且防止由于油量不足导致的润滑不良，同时由于润滑剂防止了传动轴12。在淹水路上的行驶中，不会由于吸入外部水进入差速器载体14而导致差的润滑。版权所有（C）2011，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a vehicular differential gear device for preventing the occurrence of looseness between two components constituting a differential case while eliminating the need for a plurality of fastening bolts parallel to a rotational axial center to constitute the differential case.
SOLUTION: The differential case 36 has a first split case portion 46 and a second split case portion 48 separated from each other on a plane as a boundary passing through the rotational axial center C2 and fixed to each other in the state that their split mating faces 46a, 48a mate each other. This eliminates the need for the fastening bolts parallel to the rotational axial center C2 to avoid the interference of the head of the fastening bolt with a side bearing and a bearing portion of a differential carrier and reduce the size of the differential gear device 10 in the direction of the rotational axial center C2, while preventing the occurrence of looseness between two components constituting the differential case 36. The first split case portion 46 and the second split case portion 48 are components having the same shape to allow easy manufacture and component management.
