A vehicular power unit downsized using a speed reducing mechanism of high speed reduction ratio. In a vehicular power unit, a torque applied to an input shaft from an actuator is multiplied by a speed reducing mechanism to be transmitted to an axle. The speed reducing mechanism includes: an external gear of a ring gear; a first pinion that engages with the external gear; a second pinion that rotates integrally with the first pinion; a pinion shaft that rotates integrally with the first pinion and the second pinion; a center gear that rotates integrally with a sun gear; a counter gear that engages with both of the center gear and the second pinion; and a carrier shaft that rotates integrally with a carrier. The pinion shaft is coupled to the input shaft, and the carrier shaft is coupled to the axle.
