Claim Text:
1. A multi-axis robot comprising: a base with a hollow; a support member with a hollow, the support member constituting a proximal end portion of an arm of the multi-axis robot, the support member being rotatable relative to the base around a central axis of the base; a guide pipe positioned in the support member and being rotatable together with the support member, the guide pipe having a length and including a first linear body inserted in the guide pipe in a longitudinal direction of the guide pipe, wherein a rotational center of the guide pipe deviates from a center of the first linear body, a notch, through which the first linear body is passed, is formed in a peripheral surface of an end portion of the guide pipe, the end portion being positioned in the base, the first linear body extends (i) from radially outside of the guide pipe to the notch, such that a bending portion is formed around an outer peripheral surface of the guide pipe in a plane parallel to a rotation direction of the guide pipe, and (ii) from the notch to the inner space of the support member by passing inside the guide pipe from the notch, the guide pipe is divided by a partition wall into a first passage and a second passage, the first passage and the second passage extending in an axial direction of the guide pipe, the first linear body is inserted in the first passage, a second linear body extends to an outside of the support member by passing through the second passage, and the first linear body and the second linear body are prevented from coming into contact with each other by the partition wall along the length of the guide pipe.
