PROBLEM TO BE SOLVED: To provide a joint structure of a robot, decreasing the number of parts to lower the cost and reduce the weight, simplifying assembling and facilitating design change. SOLUTION: This joint structure of a robot includes: a connecting member having at least four projected parts formed tapered on the side surface; a motor part provided with a projecting part on both sides or one side of the opposite side surfaces; a tapered recessed part fitted to the tapered projecting part of the connecting member; and a substantially L-shaped holding part provided with a through-hole in which the projecting part of the motor part is inserted, wherein the central axis of the projecting part of the motor part is on the rotating axis of the motor part, and the projecting part of the motor part is rotatably connected to the through-hole of the substantially L-shaped holding part.
