PURPOSE:To facilitate the assembly and disassembly of the input and rotary shafts of a reduction gear unit, by forming rotation limiting members on the fitting surface of the input shaft and the output shaft, and as well by forming first and second threaded parts in the front end section of the shaft. CONSTITUTION:In a coupling structure between an input shaft 12 and a rotary plate 16, the fitting surface 24 of the input shaft 12 and an output shaft 41 are formed thereon with rotation limiting members 25, 26 for limiting the relative rotation therebetween, and the front end section of the output shaft 41 is formed therein with first and second theaded sections 42, 33 for facilitating the assembly and disassembly the coupling structure. With this arrangement no unreasonable force is exerted to bearings, etc., thereby it is possible to facilitate the coupling and assembly of the coupling structure. |
