Claims

[Scope of Claim for Utility Model Registration] (1) A connecting member installed across two pipes whose open ends face each other and each of the above pipes is fastened with a male thread member to connect the two pipes. A joining structure of pipes joined in the axial direction, wherein the connecting member is divided into two in the radial direction, a through hole is formed near the end of each pipe, and a cylinder inserted into the through hole is connected to the connecting member. A joint structure for pipes, which is integrally formed so as to protrude from a member, has a female thread threaded inside the cylindrical body, and the male thread member is screwed into the female thread. (2) In claim (1), the male threaded member is formed between the male thread and the head and has a diameter increasing toward the head, and is screwed into the cylindrical body to thereby extend the cylindrical body. A joint structure for pipes having an enlarged diameter section. (3) In claim (2), the cylindrical body has a protruding end portion that protrudes from the through hole of the pipe, and the male threaded member has a diameter-enlarged cylindrical body on an end surface on the male thread side of the head. A pipe joining structure in which the protruding end portion is folded back and has a guide surface that allows the pipe to be sandwiched between connecting members.
