The end coil (12a) of this coil spring (12) includes a first portion (12a1), a second portion (12a2), and a third portion (12a3). The first portion (12a1) always contacts the spring washer, regardless of the size of the load bearing on the coil spring (12). The second portion (12a2) contacts the spring washer at times when a large load bears on the coil spring (12), and separates from the spring washer at times of small load. The third portion (12a3) is always separated from the spring washer, regardless of the magnitude of the load. An insulator sheet (50) comprising a material having rubber elasticity is attached by adhesion to the bottom surface of the wire (40) of the end coil (12a). This insulator sheet (50) is arranged on the bottom surface of an area that includes at least the second portion (12a2). |
