On the tooth surface of each internal tooth of a fixed internal gear, a meshing surface is provided that conforms to a locus on which the tooth top edge of each external tooth of a flexible external gear moves based on rotation of a wave generator. Similarly, on the tooth surface of each internal tooth of a movable internal gear, a meshing surface is provided that conforms to a locus on which the tooth top edge of each external tooth of the flexible external gear moves based on the wave generator. |
