PURPOSE:To effectively operate a rotary solenoid by projecting the vicinity of the end of a stator pole in the rotating direction, and providing an auxiliary attracting pole for generating attracting force, thereby maintaining the rotary force characteristic to the rotating angle constant. CONSTITUTION:Left and right nonmagnetic plates 8a, 8b, left and right nonmagnetic stator discs 9a, 9b of stator poles 1a, 1b and a middle common stator disc 9c are secured to the inner periphery of a stator frame 7 made of a magnetic material to form a stator 1. Magnetic rotors 15a, 15b and a common magnetic rotor 15c are secured to a rotational shaft 14 to form a rotor 3. This shaft 14 is inserted into a bearing 16 to construct a rotary solenoid. Auxiliary attracting poles 1A, 1B are provided at the ends of the poles 1a, 1b in the rotating direcrion, and the rotary force of the rotor 3 becomes constant in the all range of the rotating angle by the poles 1A, 1B. |
