This invention provides a manipulator that can facilitate a teaching method, improve the operation speed of an arm, and mount a heavy load in a narrow space. The manipulator includes a plurality of arm bodies provided in series, joint parts rotatably connecting two adjacent arm bodies, and the joint parts in which slope of rotation axes of the adjacent joints are 90 degrees, at least one linear body disposed in the joint parts coaxially with the rotation axes. The joint parts are composed of a servo motor, and a speed-reduction mechanism. The rotation axes of the servo motor, the speed-reduction mechanism and the joint parts become the same axis.

An articulated manipulator includes a base body, a first arm body, a second arm body having a second arm center axis, and a third arm body. A first joint part connects the base body and a first end portion of the first arm body rotatably around a first rotation axis. A second joint part connects a second end portion of the first arm body and a third end portion of the second arm body rotatably around a second rotation axis. A third joint part connects a fourth end portion of the second arm body and a fifth end portion of the third arm body rotatably around the third rotation axis. When the first, second and third arm bodies are all erected with respect to a installation surface, the first rotation axis, the second arm center axis, and the third rotation axis are substantially aligned with each other.

The present invention is an industrial robot with a cable spanned between and end effector and an upper arm. The cable does not twine around the upper arm or interfere with a peripheral device. A passage opening, through which the cable for supplying power, signals, or materials to an end effector attached to a rotating element is drawn out of a body, is opened at a position where the body intersects the center of a first rotational axis.

The present invention provides an industrial robot, wherein a cable or the like spanned between an end effector and an upper arm has less bending due to a motion of a wrist portion, wherein the cable or the like does not twine around the upper arm, and wherein the cable or the like does not interfere with a peripheral device.A passage opening 25, through which a cable or the like 12 for supplying power, signals or materials to an end effector 9 attached to a rotating element 7 is drawn out of a body 6, is opened at a position, at which the body 6 intersects with a center of a first axis (an R-axis). The cable or the like 12 drawn out of the passage opening 25 is extended to the end effector 9.

It is an object of the invention to provide an arm mechanism for an industrial robot in which backlash can be reduced, a transmission loss of a driving force in a reduction gear can be reduced, and attachment dimensions of a feeding apparatus in the case where a conduit cable is disposed can be made small. According to the invention, the mechanism has: a driving portion 10 which is separated from an R axis and disposed in a one-end side 3a of an arm portion 3, and in which a harmonic drive reduction gear 9 is coupled to an output shaft of an R-axis motor 8; a driven gear 11 which is supported to be rotatable around the R axis, and which is connected to another end side 3b of the arm portion 3; a passing hole 13 which is disposed along the R axis, and which is passed through the driven gear 11 in a manner that the hole is opened to the outside of the one-end side 3a of the arm portion 3, to communicate with the other-end side 3b of the arm portion 3; and a scissors gear 12 which is disposed on the output shaft of the harmonic drive reduction gear 9, and which meshes with the driven gear 11.
