To provide a vehicular drive power distribution apparatus that gives more strength to first and second disconnect-connect teeth used in a disconnect-connect mechanism.SOLUTION: An outer circumferential disconnect-connect tooth 60a disposed on an outer circumferential side of a disconnect-connect sleeve 60 is larger than an internal circumferential spline tooth 60b on an inner circumferential side of the disconnect-connect sleeve 60. Because of this, the outer circumferential disconnect-connect tooth 60a and an inner circumferential disconnect-connect tooth 56a that meshed with it are positioned so as to be beneficial for transmitting torque, and therefore, a drive power distribution apparatus is configured to give more strength to the inner circumferential disconnect-connect tooth 56a and outer circumferential disconnect-connect tooth 60a even with constraint in a space due to comprising a synchronization mechanism, thus making it possible to increase durability of the inner circumferential disconnect-connect tooth 56a and outer circumferential disconnect-connect tooth 60a.SELECTED DRAWING: Figure 4

    【課題】断接機構に用いられる第1断接歯および第2断接歯が強度の上で有利となる車両用の駆動力配分装置を提供する。【解決手段】断接スリーブ60の外周側に設けられた外周断接歯60aは断接スリーブ60の内周側の内周スプライン歯60bよりも大径となる。このため、外周断接歯60aおよびこれと噛み合う内周断接歯56aは、トルク伝達上で有利な位置にあるので、同期機構を備えることによるスペースの制約があっても、駆動力配分装置を内周断接歯56aおよび外周断接歯60aの強度の上で有利にすることができ、内周断接歯56aおよび外周断接歯60aの耐久性を高めることができる。【選択図】図4
