Abstract
An electrically driven wheel includes a wheel disc and a wheel hub; an in-wheel motor mounted within the wheel disc to drive the wheel disc and the wheel hub or to be driven by the wheel disc and the wheel hub; a brake rotor and a brake caliper suppressing rotation of the wheel disc and the wheel hub while a vehicle is moving; and a parking lock mechanism provided in the in-wheel motor separately from a brake mechanism formed of the brake rotor and the brake caliper. The parking lock mechanism is a band-type brake frictionally engaging a planetary carrier serving as an 'output portion' of a 'reduction mechanism'.
