Turning device

A turning device comprising:

• an electric motor;
• a moving gear configured to move between a first position at which rotation of an output shaft of the electric motor is able to be transmitted to a rotor and a second position at which rotation of the output shaft is unable to be transmitted to the rotor;
• a movement mechanism which includes an air cylinder;
• a lever that is connected to the air cylinder;
• and a bracket that has a first end connected to the lever and a second end connected to the moving gear, and which is configured to move the lever by the air cylinder such that the moving gear moves between the first position and the second position;
• a torque detector configured to detect a torque of the output shaft of the electric motor;
• and
• a control device configured to output a control signal to the air cylinder to move the moving gear from the first position to the second position based on the torque detected by the torque detector.
