Zusammenfassung: | An umbilical member arrangement unit for an umbilical member, having a simple structure and high rigidity, capable of avoiding interference between the umbilical member and external equipment. The unit has a guide member constituted by a first plate member attached to a front end of a wrist section, a second plate member opposed to the first plate member and a connecting member connecting the first and second plate members. A cross-sectional region of the connecting member includes the wrist axis, extends from the axis in a first radial direction by a distance not smaller than a half of a size of the umbilical member in the cross-sectional direction thereof, and extends from the axis in an axisymmetrical second radial direction by a distance not larger than a half of the size of the umbilical member, so that the umbilical member contacts the second plate member and/or the connecting member at any rotational angular position of the guide member. |
