れば、有効である。(G) Effect of the Invention According to the configuration of the present invention, the cushioning body that serves as a cushioning foot is vertically sandwiched by the case and the stopper in a sandwich shape to form the gaps G 1 and G 2 in the upper and lower parts of the device. The applied external vibration is effectively prevented by the air damper effect in addition to the vibration absorbing effect of the elastic material such as silicon rubber or urethane rubber. Especially, it is effective when it is used in an electronic device such as a video tape recorder which has a bad influence on the recording / playback screen due to external vibration.
