Claim:
1. An umbilical member arrangement structure for a parallel link robot, comprising: an umbilical member; a clamp member; a base part; a movable part positioned below the base part; and three link parts which connect the base part and the movable part, each of the three link parts including one degree-of-freedom relative to the base part, wherein each of the three link parts comprises wherein an opening is formed on a bottom surface of the base part and exists in one of two spaces defined by a plane including center axes of the pair of passive links of one of the three link parts, wherein the umbilical member is withdrawn from the opening, the umbilical member then extends through the space in which the opening exists, resulting in being parallel with the plane, and then the umbilical member reaches a lateral side portion of one of the passive link parts while extending, in a plane existing in the space, at an angle of 70 to 110 degrees with respect to a longitudinal direction of the one of the passive link parts, wherein the umbilical member is held by the clamp member which is positioned on the lateral side portion of the one of the passive link parts, and wherein the clamp member is closer to a joint, which connects the one of the passive link parts to the corresponding drive link, than to the movable part.
