PROBLEM TO BE SOLVED: To provide a drive force transmission device and a drive force distribution device, which can be miniaturized.SOLUTION: A drive force distribution device 1 comprises: an input shaft 10; a first output shaft 11; a second output shaft 12; a case member 2; an electric motor 13; a deceleration mechanism 7 that decelerates rotation of the electric motor 13 and outputs it from a deceleration rotation shaft 70; a transmission mechanism 5 that variably changes rotation speed of the first output shaft 11 with respect to the input shaft; a switch mechanism 6 that is actuated by rotation of the deceleration rotation shaft 70 of the deceleration mechanism 7 and switches a change gear ratio for the transmission mechanism 5; a clutch mechanism 3 that receives axial pressing force in H4 mode and is able to adjust drive force transmitted to the second output shaft 12; a cam mechanism 4 that is actuated by rotation of the deceleration rotation shaft 70 of the deceleration mechanism 7 and serves as a pressing force generation mechanism for applying pressing force to a clutch mechanism 3; and a torque sensor 8 that detects torque of the deceleration rotation shaft 70 of the deceleration mechanism 7.SELECTED DRAWING: Figure 2

    【課題】小型化を図ることが可能な駆動力伝達装置及び駆動力配分装置を提供する。【解決手段】駆動力配分装置1は、入力軸10と、第1出力軸11と、第2出力軸12と、ケース部材2と、電動モータ13と、電動モータ13の回転を減速して減速回転軸70から出力する減速機構7と、入力軸に対する第1出力軸11の回転速度を可変とする変速機構5と、減速機構7の減速回転軸70の回転によって作動し、変速機構5の変速比を切り替えて切替機構6と、H4モードにおいて軸方向の押圧力を受け、第2出力軸12へ伝達される駆動力を調節可能なクラッチ機構3と、減速機構7の減速回転軸70の回転によって作動し、クラッチ機構3に押圧力を付与する押圧力発生機構としてのカム機構4と、減速機構7の減速回転軸70のトルクを検出するトルクセンサ8と、を備えている。【選択図】図2
