摘要： 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.

摘要： 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.

摘要： A lower-side spring receiving member is adapted to receive a compression spring provided with an effective part, end turn parts which do not elastically deform, and rising parts located between the effective part and the end turn parts, at a lower side of the compression spring. The lower-side spring receiving member is provided with a contact part which is formed to protrude outward from an end at one side in the extending direction thereof, and which is in contact with the rising part so as not to form a gap between the contact part and the rising part. The contact part is in contact with the rising part of the compression spring by an elastic force caused by elastic deformation, regardless of a load on the compression spring.

摘要： 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.

摘要： A lower-side spring-receiving member of a suspension device, receiving a suspension spring structured to have a rising section at a lower side of the suspension spring, having a partially annular shape and including: a base end portion arranged at one end of the lower-side spring-receiving member wherein an end of the suspension spring is inserted into the base end portion; a slope portion arranged at the other end of the lower-side spring-receiving member and having a thickness in a cross-sectional view varying so as to follow a shape of the rising section of the suspension spring; and a holding portion that is arranged between the base end portion and the slope portion and holds the suspension spring, wherein the slope portion has a recess portion (Nk) formed on its bottom-surface; the recess portion includes a ridge portion is formed in a substantially mountain shape in a cross-sectional view taken along a radial direction of the partially annular shape and may be or may not be in contact with a mounting surface when no spring load of the suspension spring is applied.
