A robot, comprising: a base stand; an arm mounted to the base stand; a body mounted to the arm so as to pivotally rotate around a first axis (R-AXIS); and a swinging element mounted to the tip side of the body, so as to pivotally rotate around a second axis (B-AXIS) perpendicular to the first axis (R-AXIS), and a rotating element that rotates around a third axis (T-AXIS), which is a rotation center axis of the rotating element and perpendicular to the second axis (B-AXIS), and holds an end effector to be connected to a conduit cable mounted to the swinging element, wherein the body further includes: a bottom portion connected to the arm so as to rotate around the first axis (R-AXIS); a passage opening provided at a position centred around the first axis of the bottom portion, and formed to allow the conduit cable to pass therethrough; and a pair of members (22, 23) formed to extend respectively from the bottom portion along the direction of the first axis with keeping a spacing for accommodating the conduit cable, characterized in that the swinging element has a main body supporting the rotating element, and two parts (7b, 7c), which extend in parallel with the third axis (T-AXIS), and is shaped like a fork, wherein ends of the parts (7b, 7c) are respectively and rotatably supported by the members (22, 23), which are provided on the left and right sides of the body, so that the swinging element is axis-supported at the end of the body in a center impeller manner, the conduit cable extends to the rotating element and further to the end effector attached to an end of this element through the space between the members (22, 23) and the space between the parts (7b, 7c), a restraining piece for blocking the space between the parts (7b, 7c) and restraining the conduit cable from sticking out from between the parts (7b, 7c) is provided between the parts (7b, 7c) of the swinging element, a connecting piece for connecting the members (22, 23) of the body is provided therebetween and strains the conduit cable from hanging down from the body, and the end effector is an arc welding torch. a base stand; an arm mounted to the base stand; a body mounted to the arm so as to pivotally rotate around a first axis (R-AXIS); and a swinging element mounted to the tip side of the body, so as to pivotally rotate around a second axis (B-AXIS) perpendicular to the first axis (R-AXIS), and a rotating element that rotates around a third axis (T-AXIS), which is a rotation center axis of the rotating element and perpendicular to the second axis (B-AXIS), and holds an end effector to be connected to a conduit cable mounted to the swinging element, wherein the body further includes: a bottom portion connected to the arm so as to rotate around the first axis (R-AXIS); a passage opening provided at a position centred around the first axis of the bottom portion, and formed to allow the conduit cable to pass therethrough; and a pair of members (22, 23) formed to extend respectively from the bottom portion along the direction of the first axis with keeping a spacing for accommodating the conduit cable, a bottom portion connected to the arm so as to rotate around the first axis (R-AXIS); a passage opening provided at a position centred around the first axis of the bottom portion, and formed to allow the conduit cable to pass therethrough; and a pair of members (22, 23) formed to extend respectively from the bottom portion along the direction of the first axis with keeping a spacing for accommodating the conduit cable, characterized in that the swinging element has a main body supporting the rotating element, and two parts (7b, 7c), which extend in parallel with the third axis (T-AXIS), and is shaped like a fork, wherein ends of the parts (7b, 7c) are respectively and rotatably supported by the members (22, 23), which are provided on the left and right sides of the body, so that the swinging element is axis-supported at the end of the body in a center impeller manner, the conduit cable extends to the rotating element and further to the end effector attached to an end of this element through the space between the members (22, 23) and the space between the parts (7b, 7c), a restraining piece for blocking the space between the parts (7b, 7c) and restraining the conduit cable from sticking out from between the parts (7b, 7c) is provided between the parts (7b, 7c) of the swinging element, a connecting piece for connecting the members (22, 23) of the body is provided therebetween and strains the conduit cable from hanging down from the body, and the end effector is an arc welding torch.
