Title:
DIFFERENTIAL GEAR MECHANISM
Document Type and Number:
Japanese Patent JP2023122851
Kind Code:
A
Abstract:
To realize a differential gear mechanism which can inhibit deterioration of durability of a case part and an output shaft even if a load transmitted from an outer peripheral gear to a case part is relatively large.SOLUTION: A differential gear mechanism 10 includes: a case part 30 which houses a differential gear set; a cylindrical part 40 connected to the case part 30; and an outer peripheral gear 45 formed on an outer peripheral surface 40a of the cylindrical part 40. The cylindrical part 40 is disposed at the outer side in a radial direction R relative to the case part 30, connected to the case part 30 through a connection part 60 which is formed so as to protrude from an outer peripheral surface of the case part 30 to the outer side in the radial direction R. Openings 62 penetrating through the connection part 60 in an axial direction L are formed at multiple positions in a circumferential direction C at the connection part 60.SELECTED DRAWING: Figure 2
