Abstract
The tubehas a hollow portionand a wall portion. The tubehas mutually contacting wall portionsthat become compressed in such a way that the wall portioncomes into mutual contact in the hollow portionthrough compression by a compressing mechanism, and is designed so that the mutually contacting wall portionscome into mutual contact, and the mutually contacting wall portionsrecover upon release of the compressing mechanism. The mutually contacting wall portionshave readily contacting portions Cthat come into mutual contact at a certain level of compressing force, and contact resistant portions Sthat come into mutual contact only at a higher level of compressing force than in the readily contacting portions C. The thickness of the wall portionaround the hollow portionvaries so that the readily contacting portions Care subjected to greater force than the contact resistant portions S
