Document Type and Number:

Japanese Patent JP2020060272

Kind Code:

A

Abstract:

To provide a vehicular driving force transmission device for allowing easier insertion of a shaft into a shaft insertion hole of a hub member than conventional one.SOLUTION: When a rear wheel axle 44 is inserted into a shaft insertion hole 54a, air in the shaft insertion hole 54a flows out through a first air-vent passage P1, a second air-vent passage P2 and a communication passage P3 to an external space Sout of a coupling cover 68 along with the rear wheel axle 44 inserted thereinto. So, the rear wheel axle 44 can be more easily inserted into the shaft insertion hole 54a than the conventional case that, for example, air is hardly released from the shaft insertion hole 54a when the rear wheel axle 44 is inserted into the shaft insertion hole 54a.SELECTED DRAWING: Figure 6
