Abstract: A suspension system comprises front and rear cantilever spring arms. First end portions of the arms are fixed to a vehicle body. Second end portions of the arms extend toward a member for supporting a wheel. The second end portions are connected to each other by means of a curved section. The spring arms are formed integrally with the curved section through the medium of the matrix resin and the fibers so as to be V-shaped as viewed from above. A joint assembly is fixed to the curved section, and a hub carrier is mounted on the assembly.

Abstract: According to one embodiment, a suspension includes a load beam having a dimple portion and a flexure having a slider mounting portion. The dimple portion has a convex surface in contact with the slider mounting portion. The slider mounting portion is swingably supported by a gimbal component member. The radius of curvature of the convex surface is less than 0.15 mm. The flexure pitching resistance acting on the contact portion when the slider mounting portion swings in the pitching direction is 0.005 N or less. The phase delay of the slider mounting portion in the pitching direction relative to an undulation of a rotating disk is 200 or less.
