[0002]

2. Description of the Related Art As a rotary operation mechanism using a magnetic force, a rotary body having a magnetic surface, which transmits a strong rotational force without increasing the diameter thereof, is firstly arranged along an outer peripheral surface as shown in FIG. A drive-side rotator 18 having a magnetic peripheral surface K and being rotatable around an axis P is provided, and a second magnetic peripheral surface J facing the first magnetic peripheral surface K in a non-contact state is defined as an inner peripheral surface. And a driven-side rotator 19 rotatable around the axis P is provided. The drive-side rotator 18 is disposed between the drive-side rotator 18 and the driven-side rotator 19. A support member 1 is provided for supporting, and a bearing member L for rotatably supporting the driving-side rotator 18 around the axis P with respect to the support 1 is provided on the axis P of the first magnetic peripheral surface K. A drive transmission member 20 that is provided separately at both ends in the direction of rotation and transmits rotational driving force to the driving In towards the outside of the bearing member L in the longitudinal direction of the side rotator 18, and fixed to the driving-side rotator 18,
It is conceivable that the drive-side rotator 18 is provided so as to be rotatable around the axis P.

[0003] The rotary operation mechanism is configured to hang a rope-like body 13 such as a rope or a chain around the periphery of the drive transmission member 20 and rotate the rope-like body 13 in its longitudinal direction. The driving side rotating body 18 is rotated about the axis P by moving the driven side rotating body 18 along the driven axis, and the driven side rotating body 19 is moved to the axis P by the magnetic force acting between the two rotating bodies 18 and 19. It is to rotate around.

[0004]

According to the above-mentioned rotary operation mechanism, the length of both the rotating bodies and the magnetic peripheral surfaces along the axial direction can be increased without increasing the diameter of the rotating bodies. If you add
The area of the magnetic surface can be increased, and a stronger rotational driving force can be transmitted.

[0005] However, in the rotation operation, the operating force for operating the cord-like body hung on the drive transmission member acts around the axis of the drive transmission member, and also acts on the shaft of the drive-side rotary body. Since it also acts as a bending force with the bearing member as a fulcrum, there is a danger that the shaft will run out.

That is, since the operating force for operating the cord-like body acts on other than the rotating force of the driving-side rotating body, a loss of power occurs, the transmission efficiency of the operating force decreases, and the shaft oscillates. There is a problem that it is difficult to rotate smoothly.
Further, if excessive force is applied to the bearing member or the shaft, there is a problem in that the members are greatly consumed and the life is shortened.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to solve the above-mentioned problems and to provide a rotation operating mechanism which can be smoothly rotated and has a long life.

[0008]

In order to achieve this object, a feature of the present invention is to provide a first rotating body having a first magnetic peripheral surface along an outer peripheral surface and rotatable around an axis. Is established,
A second magnetic peripheral surface facing the first magnetic peripheral surface in a non-contact state along the inner peripheral surface, and a second rotating body rotatable around the axis is provided. In a rotary operation mechanism for transmitting the rotational force of the one rotating body about the axis to the other rotating body by a magnetic force acting on the rotating body, a support member provided between the first rotating body and the second rotating body. Bearing members for rotatably supporting the second rotator around the axis are separately provided at both ends of the second rotator in the axial direction, and a rotational driving force is applied to the second rotator. Is provided on the outer peripheral portion between the two bearing members of the second rotating body.

[0009]

According to the characteristic structure of the present invention, the second rotating body is rotatably supported around the axis with respect to the support provided between the first rotating body and the second rotating body. Bearing members are separately provided at both ends in the axial direction of the second rotating body, and a drive transmission unit for transmitting a rotational driving force to the second rotating body is provided between the outer periphery between the two bearing members of the second rotating body. The operating force applied to the drive transmission unit is transmitted to the second rotating body, and the second rotating body is evenly distributed by the two bearing members located on both sides of the drive transmission unit in the axial direction. It is supported stably.

Therefore, it is possible to reduce the loss of the operating force without causing the wobble caused by the rotation as in the prior art, and to operate with a small force, so that the life of the member can be extended. .

[0011]

Therefore, according to the rotation operating mechanism of the present invention, the rotation operation can be performed smoothly with a small force, the operability is improved, and the life of the members can be extended.
