Abstract
A heat insulation plate () is interposed between a coupling () and an adapter flange () in a main shaft () of a dynamometer (). A torque meter () is disposed between a coupling flange () that serves as a test-piece connection surface () and the adapter flange (). To surround a periphery of these, a cover () is provided. An air conditioner utilizing a refrigeration cycle supplies a cold wind to an inside space of the cover (). The heat insulation plate () suppresses heat transmission from an electric motor of the dynamometer () to the torque meter (). Therefore, the torque meter () is effectively cooled by the cold wind.
