PROBLEM TO BE SOLVED: To provide a driving force distribution device for a vehicle for suitably reducing an abnormal sound generated from a cut-off/contact device.SOLUTION: A return angle Φ around a second rotation axis C2 of a first cam member 78 when the first cam member 78 moves backward is made larger than a looseness angle Ψ up to an output shaft 62 from rear wheels 16L and 16R, so that even if a rotation speed of the output shaft 62 is reduced when a synchronizer 90 becomes nonoperation by moving the first cam member 78 backward, looseness up to the output shaft 62 from the rear wheels 16L and 16R is stopped earlier than when an outer peripheral cut-off/contact tooth 66a of a cut-off/contact sleeve 66 meshes with an inner peripheral cut-off/contact tooth 54a of a ring gear 54. Thus, a rotation speed of the output shaft 62 is recovered and in a state where difference between the rotation speed of the ring gear 54 and the rotation speed of the output shaft 62 is comparatively small, the outer peripheral cut-of/contact tooth 66a of the cut-off/contact sleeve 66 is meshed with the inner peripheral cut-off/contact tooth 54a of the ring gear 54.SELECTED DRAWING: Figure 2

    【課題】断接装置から発生する異音を好適に低減させる車両用駆動力配分装置を提供する。【解決手段】第1カム部材78が復動するときの第1カム部材78の第2回転軸線C2まわりの戻り角度Φが、後輪16L、16Rからアウトプットシャフト62までのガタ角度Ψよりも大きくされているので、第1カム部材78が復動して同期装置90が非作動となりアウトプットシャフト62の回転速度が低下しても、断接スリーブ66の外周断接歯66aがリングギヤ54の内周断接歯54aに噛み合うよりも早く、後輪16L、16Rからアウトプットシャフト62までのガタが詰められる。このため、アウトプットシャフト62の回転速度が回復し、リングギヤ54の回転速度とアウトプットシャフト62の回転速度との差が比較的小さい状態で、断接スリーブ66の外周断接歯66aがリングギヤ54の内周断接歯54aに噛み合わせられる。【選択図】図2
