A cover tube for a flexible transmission shaft is provided to keep the flexible transmission shaft clean and to make smooth power transmission through absorbing vibration or noise inside during operation. A first moving shaft(53a) and a second moving shaft(53b) are mounted on both ends of the flexible transmission shaft. The both ends of the cover tube tighten the peripheral surfaces of the first and second shafts to entirely separate the flexible transmission shaft from outside. The cover tube covers the flexible transmission shaft thoroughly and absorbs vibration or noise. And the both ends of the cover tube have a closure unit to tighten the peripheral surface of the first and second shafts. |
