A damper has a flexible portion formed of a rubber-like elastic material, such as thermoplastic elastomer, and a lid portion whose inner peripheral portion is formed of the rubber-like elastic material. The flexible portion and the lid portion are respectively equipped with mounting recesses into which mounting shaft members oppositely arranged on a casing of a reproduction device are inserted to hold the damper. With this construction, there is no need to mount the damper such that the lid portion faces the side plate or the bottom plate of the casing. Therefore, it is possible to reduce the thickness of the reproduction device, and to increase the degree of freedom in the design of the casing. Further, since the damper is supported in a floating state, it is possible to obtain a superior vibration damping effect whether the device is installed in a vertical or horizontal position.
