Provided is a motive power device that can be configured easily, that can be reduced in size and weight, and that can have reduced manufacturing costs. This motive power device has four rotating elements: a rotatable carrier (91) for rotatably supporting first and second pinion gears (P1, P2) that mesh with each other, first and second gears (S1, R1) that mesh with one of the pinion gears (P1, P2), and a third gear (S2) that meshes with the other pinion gear; and the rotational speed of the four rotating elements satisfies a collinear relationship of being aligned in a single straight line in a collinear chart. Of the four rotating elements, the first and second outer rotating elements (S1, S2), which are positioned on the outer sides in the collinear chart, are respectively connected to first and second energy input/output devices (11, 12), and first and second quasi-outer rotating elements (91, R1) positioned respectively adjacent to the first and second outer rotating elements are connected respectively to one and the other of two driven parts (SF, SR). |
