Abstract: A hollow stabilizer includes a curved part having eight regions defined in a cross section. A first region includes a 90° first part when the center of the inside of the curve is taken to be at 0° and the center of the outside of the curve is taken to be at 180°. A third region includes a 0° third part. A fifth region includes a 270° fifth part. A seventh region includes a 180° seventh part. The radii of curvature of the respective outer surfaces of the third part and the seventh part are larger and the radii of curvature of the respective outer surfaces of the second part and the sixth part are smaller than the radii of curvature of the respective outer surfaces of the fourth part and the fifth part.

Abstract: A stabilizer is provided with a restriction ring connected to a torsion portion at a connection portion adjacent to a bush. The restriction ring has a body, a female portion, a male portion, and a welded portion. The female portion has gripping portions with a spacing therebetween decreasing in the direction away from a valley bottom portion. The male portion has a neck portion, an expansion portion, and a contraction portion. The welded portion covers at least the range of the contraction portion and the valley bottom portion and melts in the plate thickness direction from the outer peripheral surface.

Abstract: A stabilizer link includes a support bar, and ball joints. The ball joint includes a ball stud including a ball portion and a stud portion, and a housing that turnably supports the ball portion of the ball stud. The stabilizer is formed of a rod-shaped member made of metal. Mounting portions to which the stabilizer links are to be joined are respectively provided at both ends of the stabilizer. Through-holes through which the stud portions of the ball studs are to be inserted are respectively provided in the mounting portions. The stabilizer link is joined to the stabilizer by press-fitting the stud portion of the ball stud into the through-hole of the mounting 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: Provided is a coil spring manufacturing method. In the coil spring manufacturing method, a coil spring of a vehicle suspension member is immersed in a fluidized bed in which powder coat is fluidized for coating. The fluidized bed includes a vertical stream area in which the powder coat moves upward and downward. The coil spring is immersed in the vertical stream area of the fluidized bed while an end coil of the coil spring faces upward, and is periodically subjected to a relative movement with respect to a direction containing components vertical to a central axis of the coil spring in relation to the vertical stream area.

Abstract: A stabilizer includes bend sections. With respect to positions in a circumferential direction of a radial cross section of each of the bend sections, a center of an inside of a bend is defined as 0°, and a center of an outside of the bend is defined as 180°. The bend sections each include a bend interior section located at 0°, a bend exterior section located at 180°, a first side section located at 90°, and a second side section located at 270°. The bend interior section has compressive residual stress from a surface to a first depth. The bend exterior section has compressive residual stress to a second depth. The first side section has compressive residual stress to a third depth. The second side section has compressive residual stress to a fourth depth.

Abstract: A fuel lid opener-has: a heart cam mechanism that is structured so as to, each time a lifter is push-operated via a fuel lid, cause the lifter to alternately repeat advancing-out and withdrawing, and so as to push the fuel lid open due to advancing-out of the lifter; and a locking mechanism-that can restrict operation of the heart cam mechanism. At the locking mechanism, a time when a stopper is moved by operation of a motor, and the aforementioned restricting is released, the aforementioned stopper engages with the heart cam mechanism and operates the heart cam mechanism. Due thereto, the lifter advances-out, and the fuel lid is pushed open.
