Abstract
An internally meshing planetary gear structure is the type having a first and second supporting blocks. The supporting blocks are rigidly connected to each other by carrier pins passing through inserting-fit holes formed on externally toothed gears. Also, the end surfaces of the carrier pins are exposed on a counter-member mounting surface of the first supporting block positioned on the counter-member side, and thus screw holes for screwing counter-member fixing bolts are formed on the end surfaces. With this arrangement, it is possible to enlarge the actual usable area of a counter-member mounting surface of the first supporting block and hence to increase the number of counter-member fixing bolts.
