<p>PURPOSE:To prevent the occurrence of trouble by coupling a plurality of link mechanisms, and so constituting the circular guide rail of a mobile frame as to perform the action of dividing it equally each geometrically similar to a pantagraph mechanism. CONSTITUTION:An elastic absorber for accommodating a cable where a plurality of off set parts in succession are formed is constituted by continuously coupling a plurality of link mechanisms in each of which a coupling frame 19 and mobile frames 13, 14, and 15 are coupled by a coupling bar 21. The coupling frame 19 is so formed as to engage with a straight-line guide rail 20 for shifting it axially, and the mobile frames 13, 14, and 15 with circular guide rails 16, 17, and 18 axially and laterally. And, the circular guide rails 16, 17, and 18 of the mobile frames 13, 14, and 15 are so constituted as to perform the action of dividing it equally each geometrically similar to a pantagraph mechanism. Hereby, the occurrence percentage of trouble or inferiority can be suppressed.</p> |
