This application provides an industrial robot in which it is possible to reduce cost while ensuring there is adequate accuracy of the position of the movable part relative to the main body part. For example, in the industrial robot (1), at a first joint part (7), a lever (3) is connected to the main body part (2) in a manner that enables rotation of the lever (3) about a first direction as an axial direction that is substantially orthogonal to the direction in which the lever (3) extends from the main body part (2). A second joint section (15) is provided with a rolling bearing that enables rotation of the arm (12) relative to the lever (3) about the first direction as the axial direction of rotation, and a rolling bearing that enables rotation of the arm (12) relative to the lever (3) about a second direction as an axial direction that is substantially orthogonal to the first direction and the length direction of the arm (12). A third joint section (18) is provided with a rolling bearing that enables rotation of the movable part (5) relative to the arm (12) about the first direction as an axial direction, and a rolling bearing that enables rotation of the movable part (5) relative to the arm (12) about the second direction as an axial direction. |
