Claims

[Claims for Utility Model Registration] (1) A fastener is screwed into a threaded portion formed on the outer periphery of a cylindrical joint body, and an outer narrowing formed on the inner periphery of the outer end of this fastener. The end of the joint main body is narrowed down and reduced in diameter by the tapered surface, and the reduced diameter end extends in the circumferential direction of the pipe wall of the connecting pipe inserted into the joint main body. 1. A connection structure for thin-walled steel pipes, which is fitted into the recessed groove, and further includes a seal packing interposed between the joint body and the end of the connection pipe. (2) The thin-walled steel pipe connection structure according to claim 1, wherein a slit-shaped notch extending in the axial direction is formed at the end of the joint body. (3) The connection of thin-walled steel pipes according to claim 1 or 2 of the utility model registration claim, in which the recessed groove in the pipe wall of the connecting pipe is pressed by the end of the joint body whose diameter has been reduced. Department structure. (4) The thin-walled steel pipe according to claim 1 or 2 of the utility model registration claim, in which the end of the reduced-diameter joint body fits into a recessed groove pre-formed in the pipe wall of the connecting pipe. Connection structure. (5) The connection structure for thin-walled steel pipes according to claim 4, in which a hook-shaped engaging portion is formed at the end of the joint body.
