Abstract
An expansion unit ( ) for converting an expansion energy of pressure-increased steam into a rotation energy of an output shaft, wherein a cover member ( ) is provided on the casing outer surface of the expansion unit ( ). The cover member ( ) has a function of sealing the end section of an output shaft ( ) protruding beyond the casing outer surface against the outside and a function of recovering steam led out from the casing and has its pressured reduced after the conversion. The end section of the output shaft ( ) provided inside the cover member ( ) and a driven-side transmission shaft ( ) disposed outside the cover member ( ) are coupled with each other via a magnet type shaft coupling ( ) so as to be able to transmit power, whereby the output shaft ( ) and the driven-side transmission shaft ( ) can be coupled without steam in the expansion unit leaking outside.
