A belt-type traction apparatus includes a herringbone toothed belt, which includes two edge parts and a center part between the two edge parts in a transverse direction of the herringbone toothed belt and connecting the edge parts in the transverse direction. The two edge parts and the center part each extend in a longitudinal direction of the herringbone toothed belt. The center part is associated with a first spring constant, the two edge parts are each associated with a second spring constant, and the first spring constant smaller than the second spring constant. Each edge part includes a tooth part and a support structure supporting the tooth part. Each support structure includes a plurality of reinforcement members extending in the longitudinal direction of the toothed belt.
