1. A magnetic head suspension comprising a supporting part that is swung around a swing center in a seek direction parallel to a disk surface directly or indirectly by an actuator, a load bending part including a leaf spring that has a proximal end portion connected to the supporting part and generates a pressing load for pressing a magnetic head slider toward the disk surface, a load beam part that is supported through the leaf spring by the supporting part and transmits the pressing load to the magnetic head slider, and a flexure part that is fixed to the load beam part and the supporting part while supporting the magnetic head slider,wherein the load beam part is bent around a load beam part-bending line that is along a suspension width direction,wherein the leaf spring is bent around a proximal side-bending line and a distal side-bending line that is positioned on a distal side of the proximal side-bending line so that the pressing load is defined by the sum of a load generated by a proximal side-bending portion at the proximal side-bending line and a load generated by a distal side-bending portion at the distal side-bending line, andwherein assuming that a length of the leaf spring in a suspension lengthwise direction that extends from a distal edge of the supporting part to a proximal end portion of the load beam part is represented by “

  • L”

    , a distance in the suspension lengthwise direction from the distal edge of the supporting part to the proximal side-bending line is represented by “

    L1” and

    a distance in the suspension lengthwise direction from the distal edge of the supporting part to the distal side-bending line is represented by “

    L2

    , a condition of L1

    0.3*L and 0.6*L≦

    L2 is satisfied.
