Abstract: A robot includes a first member and a second member that is rotationally driven about a prescribed axis with respect to the first member. The second member includes a pair of axially spaced-apart flange portions. The second member is supported by the respective flange portions so as to be rotatable about the axis. The robot also includes a balancer that is attached to the first member and the second member so as to be respectively rotatable about attachment axes that are parallel to the axis. In addition, the robot includes an adapter that is inserted between the pair of flange portions. The adapter is attached to the second member in an attachable/detachable manner and disposes the attachment axis of the balancer for the second member at a position that is radially farther inside than outer circumferential surfaces of the flange portions and that is decentered with respect to the axis.

Abstract: Provided is a robot capable of facilitating an adjusting operation of a length of a cable contained within an arm member. This robot is provided with an arm member and a cable-length adjustment member configured to adjust the length of a cable contained within the arm member. The cable-length adjustment member is removably attached to the arm member.
