Abstract:
A transportation apparatus operable to linearly transport an object includes a first transmission unit provided in a first intermediate table and which is operable to transmit torque from one of a pair of first links to one of a pair of second links. The transmission unit includes a pair of pulleys supported by a pair of first intermediate shafts and fixed to the one of the first links and the one of the second links; and an upper belt and lower belt are partially wound around the pulley in opposite directions with each other and fixed to the pulleys so as to transmit the torque. One of the pulley is divided into an upper part fixed with the upper belt and a lower fixed with the lower belt in an axial direction of the first intermediate shafts.
