To provide a vehicle drive transmission device which can achieve simplification and downsizing of a structure and avoid a difference from occurring in torque transmitted to a first output member and a second output member due to variations in engagement force of a frictional engagement device.SOLUTION: A first speed reducer 3A is a planetary gear mechanism including an input element 31A which integrally rotates with a first differential output element 22, an output element 32A which integrally rotates with a first output member 4A, and a fixed element 33A which integrally rotates with a first fixed gear 5A. A second speed reducer 3B is a planetary gear mechanism including an input element 31B which integrally rotates with a second differential output element 23, an output element 32B which integrally rotates with a second output member 4B, and a fixed element 33B which integrally rotates with a second fixed gear 5B. A first fixing gear 6A configured to engage with the first fixed gear 5A and a second fixing gear 6B configured to engage with the second fixed gear 5B integrally rotate and are engaged with a non-rotary member NR through a frictional engagement device 7.SELECTED DRAWING: Figure 1

    【課題】構成の簡素化及び小型化を図ると共に、摩擦係合装置の係合力のばらつきに起因して、第1出力部材と第2出力部材とに伝達されるトルクに差が生じることを回避可能な車両用駆動伝達装置を提供する。【解決手段】第1減速機3Aは、第1差動出力要素22と一体的に回転する入力要素31Aと、第1出力部材4Aと一体的に回転する出力要素32Aと、第1被固定ギヤ5Aと一体的に回転する固定要素33Aとを備えた遊星歯車機構であり、第2減速機3Bは、第2差動出力要素23と一体的に回転する入力要素31Bと、第2出力部材4Bと一体的に回転する出力要素32Bと、第2被固定ギヤ5Bと一体的に回転する固定要素33Bとを備えた遊星歯車機構であり、第1被固定ギヤ5Aに噛み合う第1固定ギヤ6Aと、第2被固定ギヤ5Bに噛み合う第2固定ギヤ6Bとが、互いに一体的に回転し、摩擦係合装置7を介して非回転部材NRに係合されている。【選択図】図1
