PURPOSE: A bladder type torus drum is provided to design and manufacture with the drum for weight reduction, thereby reducing the energy consumption of an industrial robot at least 10%. CONSTITUTION: A bladder type torus drum includes a rubber bladder (14), a shaft body (11), and a gas path (16). A bladder clamp (12) fastened to the rubber bladder is fastened to the shaft body in a screw tightening structure through a bladder clamp lock ring (13). The rubber bladder is a rotator formed with rubber, a rectangular bead, and a hexagonal bead. The rubber bladder is fastened to the bladder clamp and the bladder clamp lock ring at the shaft body. The shaft body has the gas path and is fastened to a gas valve (17), and the gas valve is placed on the gas path. Gas is fed to and discharged from the rubber bladder through the gas path. The bladder clamp is formed with steel, and a ring-shaped rotator. The bladder clamp is fastened to the shaft body with the bladder clamp lock ring, and fixes the bladder.
