Abstract: An elastic plate connected at both ends to a pair of supporting pieces of a supporting portion and connected at center to a member forming a load beam portion functions as a load bending portion. A balance mass member is mounted on a portion of the member forming the load beam portion positioned on a base-end side from the elastic plate. A narrowest portion of the supporting portion is positioned, with respect to the suspension lengthwise direction, between a position of a base-end of a concave portion defined the pair of supporting pieces and a position where phantom lines extending from inner side edges of arm areas of the supporting pieces intersect with a longitudinal center line of the suspension, thereby effectively reducing mass of tip-end side of the supporting portion without deteriorating rigidity of the supporting pieces.

Abstract: An elastic plate that is supported at both ends by a pair of supporting pieces of a supporting part functions as the load bending part. A portion of a load beam base plate that is positioned on a distal end side from a load bending center line of the elastic plate includes a parallel region that is fixed to the elastic plate, an intermediate region that extends to a distal end side through a proximal-side bending line along a suspension widthwise direction, and a distal region that extends to a distal end side through a distal-side bending line and is formed with a dimple with which a head-mounting region of a flexure part is brought into contact. The distal-side bending line is positioned in the vicinity of an intermediate point between the load bending center line and the dimple in a suspension lengthwise direction.

Abstract: A flexure metal plate includes distal and proximal end side-center-support plate forming regions that are positioned on distal and proximal sides within an open section. To a distal end section of a supporting part that is positioned on a distal side of the open section, first and second-distal side-metal plates are fixed so as to be positioned on an outer side of the distal end side-center-support plate forming region in a width direction, and to a proximal end section of the supporting part that is positioned on a proximal side of the open section, first and second-proximal side-metal plates are fixed so as to be positioned on an outer side of the proximal end side-center-support plate forming region in the width direction.

Abstract: A load bending part includes a pair of first elastic plate parts and a second elastic plate part. The pair of first elastic plate parts are elastically deformed in a bended manner so as to generate a first pressing load. The second elastic plate part is positioned between the pair of first elastic plate parts in the suspension widthwise direction in a state of having both ends in its longitudinal direction connected to a pair of support pieces of a supporting part, and are elastically deformed in a twisted manner around a twist axis line along the suspension widthwise direction so as to generate a second pressing load. The total of the first and second pressing loads functions as a load for pressing the magnetic head slider toward the disk surface against air pressure due to rotation of a disk surface.

Abstract: An elastic plate connected at both ends to a pair of supporting pieces of a supporting portion and connected at center to a member forming a load beam portion functions as a load bending portion, thereby enhancing impact resistance against jumping motion of a magnetic head slider.
