<P>PROBLEM TO BE SOLVED: To provide a fastening structure in which the cross-section of a fastening part has a closed curve shape other than a circular shape. <P>SOLUTION: A first member 1 has a tapered outer circumferential surface in which the intersection with a cross-section orthogonal to the rotation axis forms a part of or the whole part of a non-circular closed curve, and a second member 2 has a tapered inner circumferential surface in which the intersection with the cross-section orthogonal to the rotation axis forms a part or the whole of a closed curved substantially identical or substantially similar to the non-circular closed curve. One of the two members 1, 2 is pushed toward the other along the rotation axis by a guide mechanism provided on the outer circumferential surface of the first member 1 and on the inner circumferential surface of the second member 2 to relatively rotate the two members 1, 2. Due to the relative rotation of the two members 1, 2 along the guide mechanism, one of the first press-fitting part of the first member 1 and the second press-fitting part of the second member 2 is press-fitted in the other to fix the two members 1, 2 to each other. <P>COPYRIGHT: (C)2009,JPO&INPIT |
