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
【課題】従来に比較してシャフトをハブ部材のシャフト挿入穴に容易に挿入することができる車両用駆動力伝達装置を提供する。【解決手段】後輪車軸44がシャフト挿入穴54aに挿入されると、シャフト挿入穴54aの空気が、後輪車軸44が挿入されることにより第1空気抜き通路P1と第2空気抜き通路P2と連通路P3とを通してカップリングカバー68の外部空間Soutへ流出するので、例えば後輪車軸44がシャフト挿入穴54aに挿入されるときにシャフト挿入穴54aから空気が抜け難くい従来に比較して、後輪車軸44をシャフト挿入穴54aに容易に挿入することができる。【選択図】図6
