<p>PURPOSE:To provide the joint structure of a fluoro-resin tube through which the fluoro-resin tube can be certainly connected and its slipping out can be prevented even under strong tensile force though its structure is simple and execution is easy. CONSTITUTION:The end part of a fluoro-resin tube 2 is inserted over the outside of a fluoro-resin joint body 1 having the outer periphery of an end part formed into a thick part 1a and its inner part formed into a nonthick part 1b so as to get over the thick part 1a to the nonthick part 1b. The inserted end of the tube 2 is tightly fastened on the nonthick part from the outside by the thermal contraction of a fluoro-resin ring shaped contractive tube 3. The ring-shaped contractive tube 3 being as thick as possible is preferably used, and the back of time thick part 1a of the joint body 1 is preferably formed into a steeply inclined, rectangular or minus-inclined face.</p> |
