Claims

[Claims for Utility Model Registration] A central shaft provided coaxially with the first shaft, a connecting shaft fixed to the base end of the central shaft and extending coaxially with a second shaft perpendicular to the first shaft, and the center. a tip member externally fitted onto the shaft so as to be freely rotatable around the first shaft; a connecting member externally fitted onto the connecting shaft so as to be rotatable around the second shaft; the connecting shaft, the tip member, and the connection. A wrist body that mutually supports the wrist member rotatably, and an L-shaped passage is formed between the central axis and the connecting axis, and both ends of this passage are connected to the central axis and the connecting axis. The distal end member and the connecting member are provided with an annular groove that is continuous with each of the open ends, and a connection port that is continuous with each of the annular grooves. An industrial robot wrist with a built-in fluid passage.
