PROBLEM TO BE SOLVED: To provide a gasket with excellent dustproof property without generating outgas, and easy to attach to a seal part. SOLUTION: The material of the gasket 30 sealing the inside of the hard disk device is a composition containing (A) 100 pts.wt olefinic thermoplastic elastomer and (B) 1 to 20 pts.wt maleic anhydride modified polypropylene or a maleic anhydride modified polybutadiene as a main component. If such a material is directly injection molded on the back face of the cover 20 to integrally form the cover 20 and the gasket 30, sufficient adhesiveness is secured between the cover 20 and the gasket 30 without applying an adhesive to the back face of the cover 20 in advance.
