Claims

[Scope of utility model registration request]

A fixed part that is fixed to a wall or the like, a movable part that is supported by the fixed part and rotates at a constant speed while supporting the camera, and a deceleration mechanism provided in the fixed part, and the deceleration mechanism is configured to drive an input shaft from a source and an output shaft for rotating the movable part are arranged coaxially,
A plurality of reduction gears having two stages of externally toothed spur gears each having a large diameter portion and a small diameter portion, all having the same shape, are combined between the input shaft and the output shaft with the large diameter portion and the small diameter portion meshing with each other. A coaxial panning device characterized in that it is inserted and supported by support shafts arranged in an equilateral triangular shape at equal intervals.
