A robot includes a base. A rotation base is coupled to the base and rotatable about a rotation axis relative to the base. An arm includes a base end that is coupled to the rotation base and that is turnable relative to the rotation base about a turning axis that is approximately perpendicular to the rotation axis. A balancer is coupled to the rotation base and the arm to provide force to between the rotation base and the arm. To a first attachment portion, one end of a jig is attachable to restrict displacement of the balancer in an axial direction. The first attachment portion is disposed at a coupling portion where the balancer and the arm are coupled to each other. To second attachment portions, another end of the jig is attachable. The second attachment portions are disposed at a predetermined distance from the rotation base. |
