A robot arm includes a first arm having a base end portion rotatably connected to an arm base, and a second arm having a base end portion rotatably connected to a tip end portion of the first arm and a tip end portion to which a robot hand is rotatably connected. Further, the robot arm includes a link unit having a base end portion rotatably supported with respect to the arm base and a tip end portion inserted into the first arm at an intermediate portion of the first arm and supported to make relative rotation with respect to the first arm. The link unit rotates the second arm with respect to the first arm by transmitting the relative rotation to the base end portion of the second arm. |
