Abstract

PURPOSE:To attain thin profile as a whole even with a long coil spring in use by contacting a coil spring to a guide pin projected to the carriage side and arranging it while bending into L-shape. CONSTITUTION:A spring peg 7 is fixed on the carriage 1 and the guide pin 8 is projected to the carriage 1 at a position almost in response to a lower face of a head arm 4. Further, the coil spring 6 is hooked to the spring peg 7 for one end and the other end is contacted with the guide pin 8, then bent in L-shape and hooked to the spring peg 4a projected to the head arm 4. Through the construction above, the long coil spring 6 is arranged while being bent in L-shape, the distance in vertical direction is shortened and also the thin profile is attained as a whole.

Description

【発明の詳細な説明】 技術分野 本発明は磁気ディスク装置に係り、さらに詳しくはコイ

ドロード時の押圧力を得るように構成されている。On the other hand, a coil spring 2 denoted by reference numeral 6 is stretched between the carriage 1 and the head arm 4, and is configured to obtain a pressing force when the head is loaded.

ところが、このような構造を採用すると、安定した押圧
力を得るためには自由長の長い、ばね定数の低いコイル
スプリングを選択していた。However, when adopting such a structure, a coil spring with a long free length and a low spring constant was selected in order to obtain a stable pressing force.

を提供することを目的としてい邊。Purpose The present invention has been made in order to eliminate the above-mentioned drawbacks of the conventional art, and it is an object of the present invention to provide a magnetic disk device configured such that the overall thickness can be made thin even when a long coil spring is used. As a purpose.

実施例 以下、図面に示す実施例に基づいて本発明の詳細な説明
する。EXAMPLES Hereinafter, the present invention will be explained in detail based on examples shown in the drawings.

第２図及び第３図は本発明の一実施例を説明するもので

ャリッジ１側にガイ・ドピン８を突設しである。In this embodiment, a spring hook 7 is fixed on the carriage 1, and a guide pin 8 is provided protruding from the carriage 1 at a position substantially corresponding to the lower surface of the head arm 4.

そして、コイルスプリング６は一端を前記ばね括）７に
