摘要

A bite type pipe connection structure according to the present invention includes a first joint body, a first coupling member, and a first ferrule. The first joint body is attached to an interconnecting device. The first coupling member is screwed to the first joint body. The first ferrule is tightly held between the first joint body and the first coupling member. A diameter difference adjusting portion that has a first end and a second end is provided. The first end is connected to the first joint body, and the second end is connected to a different-diameter pipe having a diameter different from the outer diameter of the standard pipe. The different-diameter pipe is connected to the first joint body via the diameter difference adjusting portion.
