<p>PURPOSE:To form a connecting fixture with the use of a press work by coaxially aligning openings formed respectively in outer and inner plates which are then superposed with each other, and by defining an annular groove between the inner end part of the opening in the outer plate and a folded projection on the inner plate before the inner and outer plates are integrally incorporated with each other. CONSTITUTION:A connecting fixture is composed of outer and inner plates 12, 13 which are superpose with each other. The outer plate 12 is formed in its center part with an opening 14 having a predetermined diameter, and the inner plate 13 is formed in its center part with an opening 15 having a diameter smaller than that of the opening 14 in the outer plate 14. An inner end part 17 of an opening 14 formed in the outer plate 12 and an annular projection 16 formed on the inner plate 13 define therebetween an annular groove 18 adjacent to the opening 15. A bead part 3 of a rubber resilient cylinder 1 is fitted in the annular groove 18. As a result, it is possible to readily obtain a connecting fixture, thereby it is possible to remarkably lower the manufacturing cost thereof.</p> |
