PURPOSE:To reliably couple both rotational shafts by securing a boss to the end of the shaft of a rotary machine and securing a contact plate having a joint for driving the shaft of other device by fastening means. CONSTITUTION:A boss 3' of a brake drum 3 is engaged with the shaft 2 of a rotary machine 1. A repeating shaft 7 is coupled through a coupling 6 with a rotational shaft 5 of a pilot generator 4. A contact plate 8 for preventing the drum 3 from removing is integrally provided at the end of the shaft 2 of the machine 1. A spigot 9 to be engaged within the boss 3' of the drum 3 is formed at the plate 8, and a bolt inserting hole 11 to be superposed in the threaded hole 10 is formed. The plate 8 engages the spigot 9 within the boss 3' of the drum 3, the end of the plate 8 is bonded in contact with the end of the boss 3', and coupled by a bolt 12 engaged from the bolt inserting hole 11 with the hole 10. |
