[Problems to be solved by the device]

 According to the rotary operation mechanism described above, the area of the magnetic surface can be increased by increasing the lengths of both the rotating bodies and the magnetic peripheral surfaces along the axial direction without increasing the diameters of the rotating bodies. It becomes possible to transmit a stronger rotation driving force.

However, in the rotating operation, the operation force for operating the cord-shaped body hung on the drive transmission member acts around the axis of the drive transmission member, and at the same time, with respect to the shaft of the drive side rotation body. Since it also acts as a bending force with the bearing member as a fulcrum, there is a risk of sway of the shaft.

That is, since the operation force for operating the cord-like body acts in addition to the rotation force of the drive-side rotating body, a loss of force occurs, the transmission efficiency of the operation force decreases, and the shaft core There is a problem that it becomes difficult to rotate smoothly due to shake. Furthermore, if excessive force is applied to the bearing members and shafts, the wear of the members will increase and the service life will be shortened.

Therefore, an object of the present invention is to solve the above problems and provide a rotary operation mechanism that can be smoothly rotated and has a long life.
