A power unit capable of downsizing rotary motors and enhancing efficiency of the power unit. In first and second planetary gear units, a first ring gear, a first carrier, a second sun gear, a first sun gear, a second carrier, and a second ring gear, capable of transmitting power to each other, are configured such that they satisfy a collinear relationship and are in a line in a collinear chart. The first carrier and the second sun gear are connected to a prime mover, and the first sun gear and the second carrier are connected to drive wheels. The first and second ring gears are connected to the first and second rotary motors, respectively. The first and second rotary motors are connected to each other. A transmission is disposed at least between the first rotary motor and the first ring gear or between the second rotary motor and the second ring gear.
