PROBLEM TO BE SOLVED: To provide a connecting structure of a duct which can easily and accurately perform the alignment of the duct even if the duct is, for example, a blow-molded duct, and a connecting method.SOLUTION: In a connecting structure of a duct, an open end of a second duct is inserted into an open end of a first duct, and the first duct and the second duct are connected to each other. Positioning marks having inclined lines inclining to insertion directions are formed at the first duct and the second duct, and the first duct and the second duct are connected in a state of being aligned by aligning the positioning marks. It is preferable that the positioning marks may have two pieces of intersecting inclined lines. The open end of the externally-fit first duct is cut at a position traversing the inclined lines of the positioning marks.SELECTED DRAWING: Figure 1

    【課題】 例えばブロー成形されたダクトであっても、簡単且つ精度良くダクトの位置合わせを行うことが可能なダクトの連結構造及び連結方法を提供する。【解決手段】 第1のダクトの開放端内に第2のダクトの開放端が挿入され、連結されてなるダクトの連結構造である。第1のダクトと第2のダクトには、それぞれ挿入方向に対して傾斜する傾斜線を有する位置決めマークが形成され、これら位置決めマークを位置合わせすることにより互いに位置合わせされた状態で連結されている。位置決めマークは、互いに交差する2本の傾斜線を有していることが好ましい。外挿される第1のダクトの開放端は、位置決めマークの傾斜線を横切る位置で切断されている。【選択図】 図1
