Title:
STRUCTURE FOR PREVENTING NOISE AND ENTRANCE OF DUST TO DISK STORAGE DEVICE
Document Type and Number:
Japanese Patent JPH03283076
Kind Code:
A
Abstract:
PURPOSE:To prevent noise and entering of dust to a disk storage device with simple structure by projecting a rib whose apex is in press contact with other ring face along one ring face of a case and a cover and interposing a gasket between other parts than the ring shaped rib air-tightly. CONSTITUTION:A rib 21 is projected along a ring mating face MF of a case 10 and a cover 20 tightened mutually on the ring mating face MF, an apex of the rib 21 is in press contact with other ring face when the case 10 and the cover are tightened, a gasket 40 is interposed air-tightly between other parts than the rib of the ring mating face MF. Since the gasket 40 is interposed and the case 10 and the cover 20 have to be tightened only, the assembling to a seal package is facilitated. Furthermore, the degree of compressing the gasket 40 is managed accurately depending on the height of the rib 21 and no excess pressure is exerted, then the deterioration in the gasket 40 is decreased. Thus, noise and entering of dust to a disk storage device are prevented with simple structure.
