The present invention relates to a bolt coupling structure of a differential and a flange. The coupling structure comprises a differential (10), which receives power of the output axis of a transmission; side gears (12), which are arranged in both ends inside the differential (10) and coupled with drive shafts (20) on the right and left sides; a flange (100), which has an insertion space (110) by being pressed into both ends of the differential (10) and being inserted into the side gears (12) in one end; and a bolt (200), which is inserted into and coupled to the insertion space (110) of the flange (100). The coupling structure enables the differential (10) and the flange (100) to be coupled with the bolt (200), thereby increasing safety by improving the coupling force of the differential (10) and the drive shaft (20). Also, the coupling structure reduces backlash generation, thereby minimizing friction noises, and improves productivity. |
