PURPOSE:To couple the hollow shaft of the encoder of a rotating machine provided with a rotary encoder with the rotary shaft of the rotating machine body through a simple structure requiring reduced number of components and to facilitate machining work of the rotary shaft. CONSTITUTION:Hollow shaft 25 of an encoder 23 supported on the end face of a rotating machine body is projected from the body side end face and the projecting part is fitted on the end face part of the rotary shaft 27 of the body 21 while furthermore the hollow shaft 25 is tightened by means of a bolt inserted into a hollow hole 25a and coupled with the rotary shaft 27. |
