Claims

[Claims for Utility Model Registration] (1) A plurality of stators 2 are disposed annularly at predetermined intervals inside a casing 1, and a rotor 5 fixed to a shaft 6 is provided in a space inside the casing 1. In the rotary solenoid, the rotor 5 is rotatably arranged and the rotor 5 is rotated by selectively energizing the stator 2. A holding member 12 having a positioning pin 14 that can be retracted and retracted into the rotation range of the rotor 5 is provided to engage with the engaging portion 5a of the rotor 5, and the positioning pin 14 of the holding member 12 allows the rotor 5
A rotary solenoid characterized by positioning. (2) The holding members 12 are arranged corresponding to the stators 2, and the positioning pins 14 of the holding members 12 protrude and engage with the rotor 5 when the stator 12 is energized. A rotary solenoid according to claim 1 of patent registration. (3) arranging the holding member 12 at an arbitrary position;
The rotary solenoid according to claim 1, wherein the rotary solenoid protrudes and engages with the rotor 5 when the holding member 12 is energized.
