The present invention provides a self load supporting type flexible coupling structure, that is, a self-contained type flexible coupling structure configured such that a vibration problem does not occur in the flexible coupling structure which is large in total length. The present invention is configured such that: a radial spherical bearing portion (23) and a thrust spherical bearing portion (48) are incorporated in a gear coupling structure such that rotational center positions of the radial spherical bearing portion (23) and thrust spherical bearing portion (48) coincide with a crowning center position (O) of an outer gear (39); an inner gear (38) is supported by the radial spherical bearing portion (23) and the thrust spherical bearing portion (48); and the outer gear (39) is able to incline relatively with respect to the inner gear (38) based on the crowning center position (O). |
