The brackets are fixed to the mounting portion formed on the pressure vessel using a plurality of fixing bolts which are arranged in a spaced-apart manner on an eccentric circle having the center at a point x2offset from the center of rotation x1of a rotary shaft and hence, the brackets can be fixed to the mounting portion formed on the pressure vessel at a predetermined angular position which uses the point x2offset from the center of rotation x1of the rotary shaft as the center of rotation.
