[0046] Referring to FIG. 1A, a differential 10 and outer peripheral portions 19a, 19b surrounding the differential 10 are shown. As shown in the figure, the differential 10 is engaged with a drive pinion member 20 extending to the left. The drive pinion member 20 rotates to transmit power to the differential 10 . In addition, the differential device 10 has shafts 17a, 17b connected thereto, as shown in the vertical direction of the figure. When the shafts 17a, 17b receive power from the drive pinion member 20 they rotate. A differential support structure 1 rotatably supports the differential 10, drive pinion member 20 and shafts 17a, 17b relative to outer peripheral portions 19a, 19b or other similar fixed members.
[0047] The differential 10 basically has a drive pinion part 20 , shafts 17 a and 17 b , a pinion shaft 18 , a ring gear 8 , pinions 14 a and 14 b , side gears 9 a and 9 b and a differential housing 15 . The shafts 17a and 17b each have an end with two wheel me...

[0067] Referring to FIG. 6, this embodiment provides a differential device support structure in which deep groove ball bearings 7a-7d are used instead of tapered roller bearings 1a-1d.
[0068] The deep groove ball bearing 7a includes an outer ring 2a, an inner ring 3a, a ball 6a and a cage 5a. The outer ring 2a is provided at an upper, inner peripheral surface of the outer peripheral portion 19b (see FIG. 1A ). The inner ring 3 a is provided to be fitted at an upper end portion of the differential 10 . The balls 6a are located between the outer ring 2a and the inner ring 3a, and are rotatably held by the cage 5a. The deep groove ball bearing 7b includes an outer ring 2b, an inner ring 3b, a ball 6b and a cage 5b. The outer ring 2b is provided at a lower inner peripheral surface of the outer peripheral portion 19b. The inner ring 3 b is provided to be fitted at a lower end portion of the differential 10 . The balls 6a are located between the outer ring 2b and the inner rin...
