  • Inner structure of endoscope
    Patent number: 5667477
    Abstract: A tube is inserted into a second connecting member and the second connecting member is moved toward a joint ring along the tube. Then the second connecting member is housed in a housing space of the joint ring to secure a length L2 required for a connecting operation. Next, the first connecting member is pushed into the tube. Then the second connecting member is moved from the housing space along the tube so as to be coupled with the second connecting member. The tube is held between the first and the second connecting members. As a result, the length L2 of the space for connecting the pipe and the tube can be larger than the conventional length L1 by the length L3 by which the second connecting member is housed in the housing space.
