Zusammenfassung:PROBLEM TO BE SOLVED: To provide an industrial robot that is movable with small force by reducing a load applied to a lower arm. SOLUTION: The industrial robot comprises a first hydraulic actuator 10 telescopically stretched between a base 2 and the lower arm 3, a second hydraulic actuator 20 telescopically stretched between the lower arm 3 and an upper arm 4, and piping 31 and 32 interconnecting the first and second hydraulic actuators 10 and 20. When either of the first and second hydraulic actuators 10 and 20 contracts, pressurized fluid passes through the piping 31 and 32 to the other hydraulic actuator to extend the other hydraulic actuator.
