ABSTRACT:
A transfer robot has a base, first and second intermediate arms, and a distal arm. First and second pulleys are fixed to driving and driven shafts of the first intermediate arm, respectively, and a flat belt is looped around the first and second pulleys. Each of the pulleys has an inner boss and an outer collar, and an eccentric ring is attached to the boss. In each of the pulleys, the flat belt surrounds a periphery of the collar, and is introduced into the collar through a side opening of the collar, and further surrounds a periphery of the eccentric ring. The tension of the flat belt is adjustable by adjusting the position of the eccentric ring relative to the boss in an angular direction.
