<p>A lid-section mechanism for a rotor, adapted to prevent a tightened lid from loosening. The lid-section mechanism comprises the lid, a knob, a knob shaft, a circular plate, a plate spring, and an elastic body. The circular plate is mounted to a surface of the lid, said surface facing the knob, and is provided with click holes formed on a circle having a center coincident with a rotating shaft, and also with a shaft hole for allowing the knob shaft to pass therethrough. The plate spring is mounted to a surface of the knob, said surface facing the circular plate, and is adjusted in such a manner that, when the distance between the knob and the lid is less than or equal to a predetermined level, the plate spring is caught by a click hole. The elastic body is provided between the knob and the lid and presses the lid toward the rotor according to the distance between the knob and the lid. When the knob is rotated while the distance between the knob and the lid is less than or equal to the predetermined level, the plate spring repeats action in which the plate spring is caught by a click hole and is deflected and disengaged from the click hole.</p> |
