Abstract
A handling robot prevents a positioning in a motor unit power transmission system from becoming inaccurate and can eliminate occurrence of vibrations due to a twisting deformation and so forth in the system. The handling robot has an arm fastened to an outside of each of a plurality of ring bosses that are arranged coaxially and turnably. Each of such arms is connected via a link to a carrier table so that turning the ring bosses in mutally opposite directions may cause the carrier table to reciprocate in a perpendicular direction to a turning axis; and turning them in a same direction may cause the carrier table to turn. A plurality of motor units corresponding to the ring bosses are arranged coaxially with each other and at positions that are insides of the ring bosses and lower than a position where the carrier table may operate. A connecting member is further arranged and is shaped in the form of a cup in cross section and fastened to the output member of each of the motor units, such connecting members being connected to the ring bosses, respectively.
