Claims

[Claims for Utility Model Registration] (1) The pipe ends of two exhaust pipes are connected in the axial direction, and the pipe end of one exhaust pipe is formed with a curled part facing outward. Then, insert the pipe end of the other exhaust pipe into the pipe end of this one exhaust pipe, and fit the support flanges to the outer circumferences of the pipe ends of both exhaust pipes through their pipe insertion holes. , a support flange fitted over the end of one exhaust pipe is formed with a tapered surface extending from the pipe insertion hole to the joint surface thereof toward the end of the other exhaust pipe, and both support flanges An exhaust pipe joint characterized in that a tightening means for uniting these is provided, and both support flanges are tightened by the tightening means, thereby pressing a curled portion with a tapered surface. (2) A device that connects the ends of two exhaust pipes in the axial direction, where the end of one exhaust pipe is formed with a curled part facing outward, and the end of the other exhaust pipe is formed with a curled part facing outward. At the end, an annular rising closed flange is formed by rising outward to a predetermined length and then folded back, and a cylindrical part is formed at the tip side of the flange continuously from the base, and one exhaust pipe is formed. Insert the cylindrical part of the pipe end of the other exhaust pipe into the pipe end of the other exhaust pipe, fit the support flanges to the outer peripheries of the pipe ends of both exhaust pipes through their pipe insertion holes, and then A support flange fitted externally on the end of the pipe is formed with a tapered surface extending from the pipe insertion hole to the joint surface toward the end of the other exhaust pipe, and both support flanges are provided with a tapered surface. A tightening means is provided to integrate the
An exhaust pipe joint characterized in that the curled portion is pressed by a tapered surface by tightening both supporting flanges with a tightening means.
