The invention provides a rotary drive device capable of reducing the space required for mounting on a moving body main body. The rotary drive device DV in a mobile body includes a main wheel 5 and a pair of drive assemblies DP opposing each other in the axial direction AD and each driving the main wheel. The main wheel includes driven rollers 51. One of the pair of drive assemblies DA includes a motor 17, a motor case 18, a drive force transmission, and driving rollers 120. The driving rollers are in the drive force transmission along a circumferential direction CD, 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 120. At least a portion 180 of the motor case opposes at least a portion of the driving rollers in the axial direction, and is attachable to a moving body main body 3 of a moving body.
本发明提供旋转驱动装置,能够减少用于安装于移动体主体所需的空间。移动体所具有的旋转驱动装置(DV)具有主轮(5)和一对驱动部(DP)。一对驱动部在轴向(AD)上彼此对置,并分别驱动主轮。主轮具有多个被驱动辊(51)。作为一对驱动部的一方的驱动部(DA)具有马达(17)、马达壳体(18)、驱动力传递部件以及多个驱动辊(120)。多个驱动辊沿周向(CD)配置于驱动力传递部件,从轴向的一侧与多个被驱动辊的至少一部分接触。驱动力传递部件旋转而经由多个驱动辊(120)向主轮传递马达的驱动力。马达壳体的至少一部分(80)在轴向上与多个驱动辊的至少一部分对置,并能够安装于移动体的移动体主体(3)。
