螺着により結合する。2. Description of the Related Art Conventionally, for example, to connect a tube holding seat of a movable hanger to a support tube, a screw is generally used, or a nut member having a thread at each end edge of the inner diameter is used. The two tubes, each having a thread at the end of the outer diameter, are connected by screwing the nut member to the tube.

【発明が解決しようとする課題】しかしながら、前記の
従来のチューブ連結構造につき、下記のような欠点があ

き、結合力が弱い。However, the above-mentioned conventional tube connecting structure has the following disadvantages. That is, (1) connecting tubes with screws requires a twisting operation of the screws, which is troublesome. (2) If the threaded hole in the tube is broken by frequent screw twists, a new threaded hole must be made in the tube. And if a new screw hole cannot be made,
New tubes must be replaced, resulting in wasted parts. (3) Connecting both tubes by a nut member requires a large amount of twisting operation force, which is not preferable. (4) The thread of the nut member and the tube is easily broken by frequent twisting operations. (5) The coupling force by the screw or the nut member is low.
【０００４】本発明は、上記の諸課題を解決するために

チューブ連結構造を提供することをその目的とする。[0004] The present invention has been made to solve the above-mentioned problems, and an object thereof is to provide a tube connecting structure in which the connecting operation is fast and the connecting force is strong.
