7. A rotary drive device, comprising:
a pair of drive force transmissions in which a plurality of driving rollers transmitting drive force to a main wheel including a plurality of driven rollers are provided, the drive force transmissions being rotatable about a rotation axis;
a pair of decelerators to decelerate a rotation speed of an input shaft and rotating the drive force transmission at a decelerated rotation speed;
a pair of carriers accommodating at least a portion of the decelerator and opposing each other in an axial direction along the rotation axis;
at least one coupler; and
a centering support making shaft cores of the pair of carriers coaxial; wherein
the pair of carriers include a first carrier and a second carrier;
the first carrier and the second carrier are directly or indirectly coupled by the at least one coupler;
the first carrier is coupled with the centering support by the at least one coupler; and
the second carrier is coupled with the centering support by the at least one coupler.
