DIFFERENTIAL GEAR

摘要

PROBLEM TO BE SOLVED: To improve durability by stably limiting a differential by preventing dislocation of the positional relationship between a pair of mutual disc plates by fitting a pair of mutual disc plates in an inside diameter and an outside diameter. SOLUTION: A disc plate 31 forms 31g fitted to a coaxial inside diameter 1g of a differential case 1 and an inside diameter 31h fitted to a coaxial outside diameter 32h of one disc plate 32. Another disc plate 32 forms 32g fitted to a coaxial inside diameter 2g of a case cover 2 and an inside diameter 32h fitted to a coaxial inside diameter 31h of another disc plate 31. A differential gear can prevent dislocation of the positional relationship between the mutual disc plate 31 and disc plate 32 since the mutual disc plate 31 and disc plate 32 are fitted in the inside diameter 31h and an outside diameter 32h besides the disc plate 31 and the disc plate 32 are supported in an inside diameter 1g of the differential case 1 and an inside diameter 2g of the case cover 2.
