However, semiconductor devices and liquid crystal display devices are manufactured in a clean room, and if a conventional roller conveyor device is used in such a clean room, dust will be generated from the driving force transmitting portion by the round belt. There is a problem that dust and dirt are generated and pollute the inside of the clean room. It is conceivable to cover the whole place where the round belt is arranged for the purpose of preventing the influence of such dust and dirt, but this requires a cover with a considerably large dust removing device. In addition, in the mechanism for transmitting the driving force via the round belt, the life of the round belt is short, and even if one round belt provided for each conveying roller is cut, the roller conveyor device stops, so the roller conveyor is stopped. There is also a problem that the operating rate of the device is low.

Thus, the roller conveyor device 1 of this example
Then, since the rotational driving force of the drive shaft 40 can be transmitted to the driven shaft 20 in a non-contact manner, no dust or dirt is generated and the inside of the clean room is not contaminated. Moreover, the magnetic poles for transmitting the driving force can be simply arranged by alternately arranging the S poles and the N poles on the conical surfaces 71, 61 (side surfaces) of the driving umbrella wheel 70 and the driven umbrella wheel 60. It can be manufactured at low cost. Further, in the rotary driving force transmission mechanism 30, the driving side and the driven side are not in contact with each other, so that wear, heat, etc. do not occur in the components such as the umbrella car that constitute the driving side. Therefore, the roller conveyor device 1 of the present example has the advantages of high drive efficiency, quiet operation, and easy maintenance. In addition, the rotation driving force transmission mechanism 30
Since it can be configured on the side of the carrying roller 200, it is easy to perform magnetic shielding.

Further, unlike the case where the S pole and the N pole are spirally formed with respect to the drive shaft 40, when the position or number of the transport rollers 200 is changed, the drive on the drive shaft 40 is changed. Since it is only necessary to change the position and number of the umbrella cars 70, it is possible to easily cope with a design change of the roller conveyor device 1. Further, the magnetic force can be easily changed only by exchanging the driving umbrella wheel 70 and the driven umbrella wheel 60.

As described above, in the rotary drive force transmission mechanism and the roller conveyor device according to the present invention, the driven shaft and the drive shaft arranged so as to be orthogonal to each other have the S pole and the S pole in the circumferential direction. It is characterized in that an umbrella car provided with conical surfaces in which N poles are alternately configured is provided, and the conical surfaces of the umbrella car are opposed to each other with a predetermined gap. Therefore, according to the present invention, the rotational driving force of the drive shaft is transmitted from the driving umbrella car to the driven umbrella car in a non-contact manner via the magnetic force, so that no dust or dust is generated and the driven car is driven. The shaft can be rotated around the axis and does not contaminate it when placed in a clean room.
Moreover, the magnetic poles for transmitting the driving force are simply and inexpensively arranged by alternately arranging the S poles and the N poles on the conical surfaces (side surfaces) of the driving umbrella wheel and the driven umbrella wheel. Can be manufactured. Further, since it is a non-contact drive, there is an advantage that the drive efficiency is high and the drive force is quiet, and since the drive force transmitting portion is not worn, the maintenance is easy.

Further, unlike the case where the S pole and the N pole are spirally formed with respect to the drive shaft, when changing the position and the number of driven shafts (conveyance rollers), the drive shaft is Since it is only necessary to change the position and the number of the driving umbrella cars, it is possible to easily cope with design changes and the like. Moreover, the magnetic force can be easily changed only by exchanging the driving umbrella wheel and the driven umbrella wheel.
