PURPOSE: A dustproof rubber for a monitor having a speaker is provided to prevent a vibration of the speaker from being conveyed to the monitor and reduce a compression deformation of the dustproof rubber due to an assembly torque of a screw for coupling. CONSTITUTION: A dustproof rubber is consisted of an inner cylindrical part(14) formed with a rubber having a higher hardness and an outer part(17) formed with a rubber having a lower hardness, wherein the outer part is formed outside the inner cylindrical part. In the outer part, an intermediate part(11) is coupled to a boss for mounting the dustproof rubber, forward and backward flanges(10,12) are formed at the both ends of the intermediate part, and a cone part(13) is extended to the back of the backward flange and contacts with the head of a screw for coupling in assembling.
