Claim 0:
1. A robot linear-object unit comprising:
a first part comprising a connector and a plurality of cables which are all covered by a flexible sheath having a circular outer shape in cross section and which lead to a plurality of motors of a robot;
a second part comprising the plurality of cables in a loose state with the sheath removed; and
a plurality of third parts among which the plurality of cables of the first part are distributed, each of the plurality of third parts comprising a motor connector and one or more of the plurality of cables bundled together for connection to a corresponding one of the plurality of motors, and each of the plurality of third parts are covered by a flexible covering material having circular outer shapes in cross section,
wherein the second part is accommodated in a casing and is provided between the first part and the plurality of third parts,
wherein the casing is provided with a plurality of through holes that allow the first part and each of the plurality of third parts to pass therethrough,
wherein spaces between the through holes, the sheath, and the covering materials are fixed in a liquid-tight state by cable glands,
wherein the casing comprises a lidded compartment which is attachable to a movable part of the robot,
wherein the robot comprises: a rotary body that is rotatable around a first vertical axis relative to a base; a first arm that is rotatable relative to the rotary body around a second axis; a second arm that is rotatable relative to the first arm around a third axis; and a wrist unit that is attached to a distal end of the second arm,
wherein the movable part of the robot is the second arm,
wherein the first part in which the plurality of cables are all covered by the flexible sheath passes through the base and is fixedly secured to each of the rotary body and the first arm, and
wherein the casing is fixed to the second arm such that the third axis is between the casing and the wrist unit.
