Abstract

　ディスク装置は、ピックアップ装置を移動可能に保持するガイドシャフト２３１Ｂと、このガイドシャフト２３１Ｂのフォーカス方向への移動を案内する案内片２１４と、ガイドシャフト２３１Ｂのフォーカス方向と同方向に螺合する調整ねじ３３０と、案内片２１４の平面と直交する方向に移動可能に設けられるとともに、ガイドシャフト２３１Ｂの周面に当接するシャフト当接面３２３Ａ、および調整ねじ３３０の頭部３３２が当接することにより移動する調整面３２３Ｂを備えたスライダ３２０と、ガイドシャフト２３１Ｂをシャフト当接面３２３Ａに近接する側に付勢する板ばね３１２と、を具備し、シャフト当接面３２３Ａは、ガイドシャフト２３１Ｂの移動方向となす外角αが、調整面３２３Ｂと調整ねじ３３０の移動方向とがなす外角βよりも大きく設けられた。
