In this case, a movable limiting recessed part provided at the hinge part 30 limits the move of a limit part provided on the movable shaft 31 so that this limit part can be moved only inside this recessed part. Then, the slope of the movable shaft 31 is abutted with the slope of a movable bearing part and that abutted state becomes friction in the case of rotation. Namely, the friction abutting these respective slopes is determined at prescribed force by the energization of the elastic member 31a.  Therefore, since the lid part is always energized in fixed direction by the elastic member 31a, the fixed load is applied on the opening/closing rotation of the lid part.

Abstract: PURPOSE:To maintain a stable state without power consumption and heat generation by installing a soft magnetic stator having hysteresis characteristics in magnetizing characteristics, a moving permanent magnet and a solenoid magnetizing said stator. CONSTITUTION:A stator 2 is composed of a soft magnetic material having hysteresis characteristics. Magnetization induced by the magnetic pole of a rotor 1 and residual magnetization by the magnetization of a solenoid 3 are generated in the stator 2, attraction force mutually work, and the rotor 1 continuously keeps the state in which the rotor 1 is pushed against a stopper. When electricity is conducted through the solenoid 3, the rotor 1 receives clockwise force and is rotated in the direction of the arrow because the magnetic pole of the stator 2 is inverted, and revolution thereof is regulated by a stopper 5 and the rotor 1 is transferred to another stable state after conduction. The stable state is obtained under the state even when the currents of the solenoid 3 are quenched, and the state can be held continuously until electricity is conducted through the solenoid 3 in the opposite direction.
