Abstract:
A belt driving apparatus includes a driving pulley, a driven pulley and an endless toothed belt. Each of the driving pulley and the driven pulley includes an outer circumference surface provided with a plurality of teeth. The toothed belt, wound around the driving pulley and the first driven pulley, includes an inner surface provided with a plurality of teeth arranged to mesh with the teeth of the driving pulley and the first driven pulley. The belt driving apparatus also includes an idler pulley having a belt contact surface coming into contact with the outer surface of the toothed belt. As viewed along the width direction of the belt contact surface, the idler pulley includes a center portion and two end portions sandwiching the center portion. The center portion of the idler pulley is greater in diameter than each of the two end portions.

Claim (Index 8):
A transfer robot comprising:\n a belt driving apparatus; and a hand attached to the belt driving apparatus; the belt driving apparatus includes: a driving pulley including an outer circumference surface provided with a plurality of teeth; a first driven pulley including an outer circumference surface provided with a plurality of teeth; a second driven pulley including an outer circumference surface provided with a plurality of teeth; an endless toothed belt wound around the driving pulley, the first driven pulley and the second driven pulley, the toothed belt including an inner surface provided with a plurality of teeth meshing with the plurality of teeth of each of the driving pulley, the first driven pulley and the second driven pulley; and first and second idler pulleys each including a belt contact surface in contact with a flat outer surface of the toothed belt, each of the first idler pulley and the second idler pulley including, along a width direction of the belt contact surface, a large-diameter portion and two small-diameter portions sandwiching the large-diameter portion, the large-diameter portion being greater in diameter than each of the two small-diameter portions, wherein the first idler pulley and the second idler pulley are arranged to sandwich the driving pulley in a travel direction of the toothed belt, and with respect to each of the first and the second idler pulleys, the flat outer surface of the toothed belt is located between the plurality of the teeth of the inner surface of the toothed belt and each of the large-diameter portion and the two small-diameter portions.
