Abstract: An end turn portion of a coil spring includes a first portion, a second portion, and a third portion. The first portion is always in contact with a spring seat irrespective of the magnitude of a load applied to the coil spring. The second portion contacts the spring seat when the load applied to the coil spring is large, and is separated from the spring seat when the load is small. The third portion is always separated from the spring seat irrespective of the magnitude of the load. An insulating sheet made of a material having rubber elasticity is attached to a lower surface of a wire at the end turn portion by means of adhesive bonding. The insulating sheet is provided on a lower surface of a region including at least the second portion.

Abstract: A stabilizer includes a stabilizer bar and a rubber bush. The stabilizer bar includes a bar body made of a steel and a coating film covering the bar body. The coating film is formed on the surface of the bar body by using a resin having a water contact angle of more than 65°. By performing surface treatment for reducing the contact angle of the coating film present on an attachment part, the contact angle of the attachment part is changed to 65° or less. A pre-cured liquid adhesive agent is applied to an inner surface (adhesion surface) of the rubber bush. After a region including the attachment part of the stabilizer bar is heated, the rubber bush is overlaid on the attachment part. The adhesive agent is cured in a state where the rubber bush is pressed.

Abstract: A stabilizer device includes a stabilizer extending in a width direction of a vehicle, and a bush unit. The bush unit includes a bracket formed of metal, and a rubber bush. The rubber bush is formed of a plurality of bush pieces, and is fixed to the stabilizer by an adhesion layer. The adhesion layer is constituted of an adhesion member including an adhesive applied to inner surfaces of the bush pieces. A bonding display portion formed of a part of the adhesion member is provided at a corner on an end face of the bush piece.
