PROBLEM TO BE SOLVED: To supply control oil pressure and lubricating oil to a gearbox and a hydraulic friction element with simple constitution. SOLUTION: Oil passage structure has an oil passage system mainly composed of an oil passage 44e formed at a motor support 44 and oil passages 1b, 1c formed at a rotating shaft, so as to supply clutch control oil pressure to a clutch oil chamber 27a, and an oil passage system mainly composed of an oil passage 44e' formed at the motor support and an oil passage 50 formed between a sun gear boss part 21a and the rotating shaft, so as to supply lubricating oil to the lubricated part of a planetary gear unit 20. Control oil pressure supply to pulley oil chambers 33d, 33e of a belt type continuously variable transmission is performed through oil passages 43a, 43b, 31a, 31b, 31c on the transmission rear side.
