<p>The present invention relates to a contra-rotating mechanism. The contra-rotating mechanism includes: a master shaft and a slave shaft arranged coaxially to each other and which contra-rotate with respect to one another; a master driving member which rotates integrally with the master shaft; a plurality of electrically driven units arranged in a radial shape and symmetrically to each other from the master driving member to receive the rotation of the master driving member; a plurality of receiving units interposed between the plurality of electrically driven units radial and symmetrical to each other from the slave shaft to reverse the rotation of the electrically driven units at least once; a slave driving member disposed on the center of the plurality of reversing units to receive the rotation of the reversing units and to rotate integrally with the slave shaft; a first panel and a second panel opposed to each other on the outside of the master driving member, the plurality of electrically driven units, the plurality of reversing units, and the slave driving member, and which support the master shaft, the plurality of electrically driven units, the plurality of reversing units, and the slave shaft such that they are rotatable; and a movement prevention unit for preventing the movement of at least one of either the assembly of the slave shaft and the slave driving member or the assembly of the master shaft and the master driving member.</p> |
