Abstract

The present invention relates to a suspension device for a magnetic disk drive incorporated in an information processing device such as a personal computer, for example. This device has support plate devices 3, 7 that also serve as bracket arms, has a rigid body portion 13 and a spring portion 15 and loads a load on a contact 49 at the front end of the load plate, and is characterized in that, in this device, the support plate The board device 3, 7 is formed by at least two layers of boards 3, 7, the board thickness t2 of at least one side 7 of the boards 3, 7 can be etched to form a high-precision hole, and the pivot hole is formed on the board 7 having the board thickness t2 31. On the other side of the plate 3, a rotation fitting hole that is approximately concentric with the pivot hole 31 and has a larger diameter than the pivot hole 31 is formed. In this way, the flatness of the long floor portion and the accuracy of the pivot hole can be improved.

Description

technical field [0001] The present invention relates to a suspension device for a disk drive built in an information processing device such as a personal computer, for example. Background technique [0002] So far, the bottom plate of the suspension device (hereinafter referred to as the suspension device) for the disk drive is welded to one end of the load plate, and the bottom plate is used to install the suspension device on the bracket arm. These suspension devices are arranged in the vertical direction between the carrier arm and the surface of each magnetic disk, so that the overall height is high and the miniaturization is limited. [0003] In this regard, as recorded in Japanese Patent No. 3089360 Figure 16 , Figure 17 scheme. like Figure 16 , Figure 17 As shown, the device is that the carrier plate 105 is welded on the long bottom plate 103 of the suspension device 101 . The long bottom plate 103 has a pivot hole 107 . The pivot hole 107 is fitted with a br...
