PURPOSE: A dust cover for a vehicle is provided to restrain the transmission of the noise of a steering device to a vehicle body by making a dust cover vibrating in the amplitude the same as a valve housing. CONSTITUTION: A dust cover for a vehicle comprises a sound-proof screen(2) having a fitting unit in the center and formed in a conical shape, a sound-proof pad(4) having a through hole fitted with the fitting unit of the sound-proof screen, and a sound absorbing sponge(6) fitted to the outer face of the sound-proof screen and elastically supporting the sound-proof screen. The dust cover vibrates in the amplitude the same as a valve housing(40). Therefore, the noise of an engine room and the hysteresis noise are reduced.
