PROBLEM TO BE SOLVED: To provide a rotary electric machine capable of working as a magnetic gear either when energized or not so as to perform power transmission, and a vehicle power transmission device thereof.SOLUTION: The rotary electric machine includes: a power transmission mechanism 10 comprising a first rotor 11 having n pieces of soft magnetic materials, a second rotor 12 having k pieces of soft magnetic materials, a third rotor 13 having magnets 13b which constitute m (m is an integer of one or larger) pairs of poles, and transmitting power with electro magnetic force; and an armature 101 which is arranged facing the third rotor 13. The first rotor 11, the second rotor 12, and the third rotor 13 are arranged and arrayed so that they are magnetically coupled with each other. The soft magnetic materials and the magnet 13b satisfy a relation of 2m=|k±n|. According to this configuration, the rotary electric machine works as a magnetic gear either when energized or not only with the first rotor 11, the second rotor 12, and the third rotor 13, so as to perform power transmission. |
