To avoid reduction of a transmission efficiency of a driving force generated at a part of a conveying passage and to enhance a conveying ability of a taper curve conveyor using a magnetic wheel.

In the conveyor, taper rollers 3 are radially arranged in plane view and an approximately circular conveying passage a is constituted on a conveyor body A'. Respective driven magnetic wheels 2, 2' are provided at center sides of the respective taper rollers 3 and driving magnetic wheels 1, 1' crossing in the state of approaching to these driven magnetic wheels are pivotally supported at the center sides. The driving magnetic wheels 1 are divided at a center and are arranged below two rows of driven magnetic wheels at a half part side. The driving magnetic wheels 1' at the other half part are arranged above a row of the driven magnetic wheels 2' and these driving magnetic wheels and the driven magnetic wheels are crossed each other. Both driving magnetic wheels 1, 1' are rotated and driven through respective driving transmission means 11 and the driving magnetic wheels 1' at the half part is reversely rotated against rotation of the driving magnetic wheel 1 at the other half.
