摘要： In a lubrication groove, which is formed in an insertion hole into which is inserted an output shaft, and which winds around the circumference of the insertion hole while advancing in the axial direction of the insertion hole, there is a portion that is farther to the outside than a perpendicular plane that is perpendicular to a center plane of a differential case on which lie the axial centers of the insertion hole and a pinion gear shaft, the perpendicular plane including a line of intersection of the center plane and the insertion hole. That portion is a perpendicular groove portion which is parallel to a plane that is perpendicular to the axial center of the insertion hole. Accordingly, when extracting a core for forming the insertion hole and the lubrication groove from a die, projections formed on the core for forming the lubrication groove will not interfere with the die. As a result, it is possible to form the lubrication groove during casting of the differential case using that core.

摘要： A support structure for supporting a brake, as a frictional coupling device, includes a snap ring, a friction plate, and a back plate. The snap ring fits in a groove that extends in a circle. The back plate is disposed between the friction plate and the snap ring. The back plate is pressed against the snap ring. The snap ring has a first end face that faces the back plate and a second end face that faces the opposite side from the first end face and is in contact with a sidewall of the groove. The back plate has an end face that is in contact with the first end face. The static friction coefficient between the first end face of the snap ring and the end face of the back plate is smaller than that between the second end face of the snap ring and the sidewall of the groove.

摘要： A differential gear unit divides an input driving force into first and second outputs, and permits a difference between the first and second outputs. The differential gear unit includes a differential case serving as a casing that defines an internal space and an opening communicated with the internal space and that is rotatable in a given direction and an opposite direction. The differential case includes a flange portion as an input portion to which the driving force is input. The differential case is configured such that the fatigue life of the differential case when the driving force is repeatedly input in the flange portion in the direction R1 is longer than the fatigue life of the differential case when the driving force is repeatedly input in the flange portion in the opposite direction; R1 is the rotational direction in which the vehicle runs forward.

摘要： A diaphragm spring is formed so as to be elastically deformable between a first shape for maintaining an engaged state for engaging a brake disc with a pressed plate without requiring the continuous operation of a hydraulic cylinder, and a second shape for maintaining a disengaged state for disengaging the brake disc from the pressed plate without requiring the operation of the hydraulic cylinder. Therefore, after the shape of the diaphragm spring is made one of the first shape and the second shape due to temporary operation of the hydraulic cylinder, power for continuously operating the hydraulic cylinder for maintaining the engaged state or the disengaged state is not required. As a result, an energy loss is not caused, and the fuel efficiency is increased.
