Abstract: PURPOSE:To improve durability against a rapid fluctuation in torque by providing a differential case to contain a differential mechanism coupled to a pair of output shafts, a ring gear geared with an input shaft and performing relative rotation at a given angle with the differential case, and a resilient member to regulate relative rotation therebetween. CONSTITUTION:Torque from an input shaft 40 is transmitted from a drive pinion 12 to a ring gear 14. When the torque is below given torque, resilient deformation does not occur to a resilient member 44 and a tongue gear 14, a flange 34, and a differential case body 24 are integrally rotated through the resilient member 44. Torque transmitted to a differential gear 22 through a differential spider 28 and a differential pinion 26 is outputted from right and left wheel drive shafts 20 and 18. When the torque exceeds the given torque, the resilient member 44 is resiliently deformed, the ring gear 14 and the flange 34 are started to effect relative rotation, the torque is outputted from the right and left wheel drive shafts 20 and 18. This constitution relieves a load exerted on a gear part between the input shaft and the ring gear and prevents breakage of a gear.
