PROBLEM TO BE SOLVED: To provide a robot arm which is used to increase the location controlling accuracy of an arm. SOLUTION: A robot arm 1 is comprised of the first arm 3 mounted turnably on a robot body 10 via the first transmittal mechanism 2, and a working means 5 mounted turnably on the tip of the first arm 3 via the second transmittal mechanism 4, and also, provided with the first coupling means 6 which transmits power by coupling the first transmittal mechanism 2 with the second transmittal mechanism 4. The first coupling means 6 is comprised of the first power transmitting portion 7 which gives and receives power from the first transmittal mechanism 2 or power to the first transmittal mechanism 2, the second power transmitting portion 8 which gives and receives power from the second transmittal mechanism 4 or power to the second transmittal mechanism 4, and the first coupling portion 9 which links the first power transmitting portion 7 and the second power transmitting portion 8 together.
