To provide a vehicular power transmission device capable of preventing occurrence of backlash noise during stop and at low speed of a vehicle, and preventing deterioration of power transmission efficiency due to drag resistance at intermediate and high speed of the vehicle.SOLUTION: In a vehicular power transmission device P, a brake mechanism 100 is configured by providing a return spring (energizing means)103 that pivotally supports a centrifugal weight 102 rotatably and energizes the centrifugal weight 102 toward an inner ring 5A of a bearing 5 fixed to the radial inner side of the centrifugal weight in a gear 31a. The brake mechanism 100 causes the centrifugal weight 102 to abut on the inner ring 5A of the bearing 5 when rotating speed of the output gear 31a is a set value or smaller, and rotates the centrifugal weight 102 by centrifugal force applied to the centrifugal weight 102 to separate it from the inner ring 5A of the bearing 5 when rotating speed of the output gear 31a exceeds the set value.SELECTED DRAWING: Figure 6

    【課題】車両の停止時および低速時のバックラッシュ音の発生を防ぐとともに、車両の中・高速時における引き摺り抵抗による動力伝達効率の低下を防ぐことができる車両用動力伝達装置を提供すること。【解決手段】車両用動力伝達装置Pにおいて、ギヤ31aに、遠心ウェイト102を回動可能に軸支するとともに、該遠心ウェイト102をこれよりも径方向内方に固設された軸受5の内輪5Aに向けて付勢するリターンスプリング(付勢手段)103を設けてブレーキ機構100を構成し、該ブレーキ機構100は、出力ギヤ31aの回転速度が設定値以下である場合には、遠心ウェイト102を軸受5の内輪5Aに当接させ、出力ギヤ31aの回転速度が設定値を超えると、遠心ウェイト102に作用する遠心力によって該遠心ウェイト102を回動させてこれを軸受5の内輪5Aから離脱させるようにする。【選択図】図6
