PROBLEM TO BE SOLVED: To couple both members to be coupled by a simple structure. SOLUTION: One member 1 to be coupled is formed by a hollow cylindrical pipe, a lower end of its hollow part 1a is opened, and an engagement protruding part 4 is protrudedly provided in the one member 1. Another member 2 to be coupled is composed of a base material 6, and a columnar engagement pillar 7 erected on the base material 6 and fitted in the one member 1. An engagement groove 8 for fitting in the engagement protruding part 4 is formed on an outer circumferential face of the engagement pillar 7. The engagement groove 8 is composed of a lead-in groove part 8a with a side for inserting the engagement protruding part 4 opened and formed along an axial direction of the engagement pillar 7, and a tapered groove part 8c continuous with the lead-in groove 8a in a base material 6 side and bending in a circumferential direction toward the base material 6 side. Both members 1 and 2 are coupled by engaging and positioning the engagement protruding part 4 in the tapered groove part 8c, and pressing a lower end face 1b of the one member 1 and the base material 6 of the other member 2 against each other.
