- the bent portion 183 bent at a predetermined angle ⁇ is formed.
- the rotation direction of the rotating body 120 rotates to the left in a counterclockwise direction, and the bent portion 183 of the rotating support 180 is opposite to the rotating direction of the rotating body 120. Bend in the direction.
- the resistance plate 190 may be prevented from rotating by the centrifugal force of the rotation support 180.
- the resistance plate 190 may be rotated by the centrifugal force caused by the rotation of the rotor 120 in the state in which the resistance plate 190 is superimposed on the rotation support 180, but this is formed by forming the bent portion 183. You can prevent it.
