Document Type and Number:
WIPO Patent Application WO/2023/026435
Kind Code:
A1
Abstract:
Conventionally, there has been a demand for the joint structure of a robot to be made compact. In the present invention, a joint structure 50 of a robot comprises: a fixed part 136; a rotating part 134 which is provided to the fixed part 136 so as to be rotatable about an axis J4 and which has a first rotating element 56 and a second rotating element 90 provided between the first rotating element 56 and the fixed part 136; and a protective tube 58 which is disposed inside the fixed part 136 and the rotating part 134, which has a cylindrical section 112 and a flange section 114, and which has a filament body 26 wired so as to pass through the inside of the cylindrical section 112. The protective tube 58 is held such that the cylindrical section 112 extends in parallel to the axis J4 as a result of the flange section 114 being sandwiched and held between the first rotating element 56 and the second rotating element 90.
