Abstract: A bush- and bracket-integrated stabilizer bar includes a stabilizer bar, a rubber bush attached to an outer periphery of the stabilizer bar, and a bracket configured to mount the stabilizer bar to a bottom of a vehicle body with the rubber bush intervened. The stabilizer bar has amine-based curable epoxy paint or amine-containing cationic paint and a surface treatment layer containing a halogen donor-based surface treatment agent on the paint. The rubber bush has a surface treatment layer containing a halogen donor-based surface treatment agent on an inner surface thereof. A thermosetting epoxy adhesive layer containing an amine-based or an organic hydrazide-based curing agent and a bisphenol type epoxy resin is formed between the stabilizer bar and the rubber bush.

Abstract: A suspension coil spring device may include a compression coil spring (10) that has a coating film, a rubber vibration isolator, and an adhesive layer that joins the compression coil spring and the rubber vibration isolator to each other. The adhesive layer is a cured product of a hot melt adhesive that melts at 80° C. to 100° C. A softening point of the hot melt adhesive is lower than a heat-resistant temperature of the coating film. The softening point of the hot melt adhesive is lower than a heat-resistant temperature of the rubber vibration isolator.
