Differential gear is used in the purpose to make turn over at the automatic car. Then, the differential gear is generally composed of plural bevel gears. Because plural bevel gears in the differential gear mesh at the same time and the structure is complicated, there are few studies for each bevel gear. The axial hole diameter of the differential pinion becomes slightly bigger than the gear shaft diameter to turn around the shaft. The interval between the axial hole and the gear shaft is thin, so it is necessary to take an influence with this special shape into consideration. Therefore, in this paoer, the approximate formula with the deflection influence function of the differential pinion tooth in revolving was made in considering the special shape as mentioned above. Then, the load distribution on the contact line of the differential gear tooth was calculated by using the influence function. Moreover, the bending moment influence function was derived and tooth root stress was calculated. Effects of the axial hole of the differential pinion on load distribution and tooth root stress are clarified. These calculated values were compared with the measured values, and validity this calculation method was examined.
