PROBLEM TO BE SOLVED: To provide a rotation range restriction device capable of reducing a number of components, and reducing size of the device.SOLUTION: A rotation range restriction device 10 comprises: a rotor 20 capable of mounting a structure 11 thereon; and a solid body 30 for rotatably supporting the rotor 20. A slide guide part 24 is disposed on one of facing surfaces 212 of the facing rotor 20 and solid body 30. The slide guide part 24 is disposed in an arc shape. The slide guide part 24 has a piece 26 capable of moving toward inside. An engagement part 36 is disposed on the other facing surface 301. The engagement part 36 is disposed to project in the slide guide part 24 side on a position where has length same to diameter of the slide guide part 24, and can contact the piece 26. Therefore the rotor 20 can be mechanically limited in a range of 360° or more and 720° or less, therefore a number of components can be reduced and size of the device can be reduced. |
