SOLUTION: A support 25 that supports the rear end 10a of the output shaft 10 is provided on the rear of the casing 6 in a manner attachable to or detachable from the casing 6. The support 25 is provided with a bracket 25g having a tapped hole 27 for disassembling situated nearly concentrically with the output shaft 10. The hole 27 is exposed by detaching the casing rear wall 7. An attachment bolt 17 is screwed in the hole 27 and is screwed inward in the state in which its front end is abutted against the rear end surface 10b of the output shaft 10 to enable the support 25 to be disassembled by backwardly pulling and moving the support 25 by the help of the attachment bolt 17.
