Abstract
A rotary drive device in a mobile body includes a main wheel and a pair of drive assemblies opposing each other and each driving the main wheel. The main wheel includes driven rollers. One of the pair of drive assemblies includes a motor, a motor case, a drive force transmission, and driving rollers. The driving rollers are in the drive force transmission along a circumferential direction, and contact at least a portion of the driven rollers from one side of the rotary drive device of the axial direction. The drive force transmission rotates to transmit a drive force of the motor to the main wheel via the driving rollers. At least a portion of the motor case opposes at least a portion of the driving rollers in the axial direction.
