PURPOSE: A suspension is provided to increase the natural frequency of a torsion mode by forming a partial thickness region on a center of a bending portion, and to form plural ribs on both sides of a load beam, to increase the natural frequency of a resonant mode, thereby guaranteeing stability and reducing a focusing error. CONSTITUTION: A base plate(21) controls a degree of freedom. A bending region(23) is formed to have a bending property from the base plate(21). A partial thickness region(25) is formed thinner than the bending region(23) on a center of the bending region(23) to prevent torsion. A load beam(29) is connected to the partial thickness region(25) and the bending region(23), and is formed with a slide(27) such that the slide(27) can widen in horizontal direction from a surface contacted section. Plural ribs(31) are thicker than the section of the load beam(29), and are formed on both sides of the load beam(29), respectively.
