arranged along the first wrist element and the second wrist element, a
flexible tabular guide member having a first end fixed on the second
wrist element and a second end constituting a free end extended in a
curve along the first wrist element and the second wrist element in the
direction from the second element toward the first wrist element to guide
the umbilical member between the first end and the second end, a
displacement limiting member mounted at the second end of the flexible
tabular guide member to limit the range of displacement of the second
end, mainly in a thickness direction of the flexible tabular guide
member, and an insertion member arranged near the second end of the
