<p>In order to provide a disk drive in which strength in the connection between a traverse unit and a body frame is improved, and reliability is high so that an attached traverse unit does not fall off; the disk drive includes a traverse unit (11) having a traverse holder (18) holding a front end of a traverse chassis (17) and being formed from a front (20) holding the front end of the traverse chassis and both support arms (21, 21) extending rearward from both ends of the front. Each of the support arms is integrally provided with an upwardly protruded vertical-rib (21 c) and its end and base have a protrusive shaft (21 a) and a guide boss (21 b), which are protruded outward, respectively. On both sidewalls (24a, 24b) of the body frame (10), vertical guide grooves (23a, 23a) into which guide bosses on the support arms fit, guide ribs (27a, 27a and 27b, 27b) drooping parallel via spaces into which the vertical ribs fit, and horizontal support ribs (29a, 29b) for rotatably pinching the protrusive shafts on the traverse holder between them and the guide ribs are integrally molded using a resin material. The protrusive shafts on the traverse holder are pinched by the guide ribs and both the horizontal support ribs, thereby the shafts become pivots of rotation of the traverse holder, the vertical ribs on the support arms are fitted into spaces between the guide ribs, thereby a lateral position of the traverse unit is regulated, and the guide bosses are freely fitted into the vertical guide grooves and the boss protruded from the front is freely fitted into the cam groove on the slide cam body, thereby vertical movement of the traverse unit is regulated. <IMAGE></p> |
