Summary:In a suspension used in an actuator of a hard disk drive, a limiter mechanism is to be provided which produces little dust and which can restrict deformation of a gimbals even against a strong shock. According to one embodiment, when a weak shock is applied to the suspension, a limiter tab and a back side of a load beam come into contact with each other to prevent a gimbals from being largely deformed by the shock. Since deformation of the gimbals is restricted by surface contact of both load beam and limiter tab, the generation of dust is suppressed effectively. When a strong shock is applied to the suspension, the limiter tab is deformed and a projecting portion of a restrictive aperture and an end portion of a limiter tab aperture come into contact with each other. The projecting portion retains the limiter tab to restrict a further deformation of the gimbals.
