PROBLEM TO BE SOLVED: To facilitate the fitting work by a simple constitution and prevent the sound from vibration by inserting a vibration damping material inside a coil of a coil spring. SOLUTION: A vibration isolating material 1152 is inserted inside a coil of a coil spring 152. The vibration isolating material 1152 is formed of an elastic material such as rubber material, a forming agent, and elastomer, is cylindrical and has a slit formed in its side whole length. The outer circumferential diameter of the vibration isolating material 1152 is smaller than the inside diameter of the spring 152 and larger than a clearance 152A formed of a bent-up 152A in the end and a spring internal circumference so that the slit is a little opened and, while the bent-up 152A is let to pass therethrough, the vibration isolating material 1152 is inserted in the coil inside. This constitution can facilitate the installation and closely stick the slit therein by the elasticity after the installation so as to surely hold it without slipping off from the clearance 152B. The fitting works can be thus facilitated by a simple constitution and the sound by the vibration can be prevented.
