Abstract
A power transmission device includes a transmission mechanism including a planetary gear set, a first engagement element, and a second engagement element. The first engagement element is a band brake configured to be engaged when the transmission mechanism is in a low gear speed. The second engagement element is a multi-plate friction clutch configured to be engaged when the transmission mechanism is in a high gear speed. The multi-plate friction clutch includes a driven plate and a drive plate. The band brake overlaps with the driven plate and the drive plate of the multi-plate friction clutch in a radial direction.
