To provide the robot structure which prevents turning movements from interfering with wiring filament bodies, and restrain costs from being higher.

The first axis reduction gear mechanism 12 of a first axis driving motor 13 is connected with a reduction gear mounting base 11 mounted to a robot fixing base 10. A first arm AM1 is connected with the housing of a reduction gear mounting base 35 by way of a third axis reduction gear mechanism 31, and the housing of the reduction gear mounting base 35 is connected with a second arm AM by way of the fourth axis reduction gear mechanism 41 of a fourth axis driving motor 42. A fifth axis driving motor 52 is disposed in the inside of the second arm AM2, and a fifth axis reduction gear mechanism 51 is disposed to the side surface of the second arm AM2. The sixth reduction gear mechanism 61 of a sixth axis motor 62 is mounted to the housing of a reduction gear mechanism mounting base 60. A cable CB is wired in such a way that it can pass through a hollow part 14, the outside of a second reduction gear mechanism 21, above the first arm AM1, the hollow part 33 of the third axis reduction gear mechanism 31, and the hollow part 43 of the fourth axis reduction gear mechanism 41.
