<p>PROBLEM TO BE SOLVED: To weld an attaching member to a rubber vibration isolator without any thermal effect. SOLUTION: A cylindrical bush 1 is constituted of an outer cylinder 2, an inner cylinder 3 and a vibrationproof rubber 4, and an attaching seat 5 is outwardly projected and provided on the outer periphery of the outer cylinder 2. The attaching seat 5 is constituted of two-staged circular stage parts 6, 7, the end surface 11 of a pipe-like attaching member 10 is brought in contact with it, and a part subjected to welding as the outer periphery of the contact part for the end surface 11 and the circular stage part 6 is welded by laser beams over the whole circumference.</p> |
