<p>The present invention employs a high elastic body with E value more than 1.2 x 10<4> kg/cm<2> to be used for a body frame (5) which supports a mechanical chassis (2) of optical disk equipment or the like, and also employs an elastic body (1) with E value less than 1.0 x 10<4> kg/cm<2> which aims at vibration damping and with rubber hardness JIS-A Class less than 70 as a low elastic body to be used for an installing portion of the mechanical chassis. By integral-molding both the low and high elastic bodies, a frame damper is formed, thereby controlling and isolating even vibration caused by high double-speed rotation of a disk (3). Also, by integral-molding both the low elastic body (1) of the installing portion of the mechanical chassis (2) and the high elastic body of the body frame (5), an assembly process using a fixing pin is avoided and working efficiency is improved. <IMAGE></p> |
