Since the impact is transmitted to the first casing 1 via the second liquid 4 and the second liquid 4, the impact from the outside is reduced and transmitted. In addition, the influence of movement to the first casing 1 due to inertial force is caused by the movement of the first casing 1 because the first liquid 3 and the second liquid 4 flow. The resistance is absorbed and the movement of the first housing 1 in the second housing 2 is suppressed.

動に対して抑制効果が向上する。Further, two kinds of liquids are filled between the two housings as a cushioning material. In addition to these, an elastic member or a wire is inserted between the first housing and the second housing. Is also good. Specifically, a coil spring or the like is attached to each surface of the first casing and the second casing that face each other, and a wire that restricts the movement of the first casing is provided outside the first casing and the second casing. You may connect with the inside of. As a result, the large movement of the first casing in the second casing is suppressed, and in addition to the effect of the cushioning material, the effect of suppressing shock and vibration is further improved.

The transmission of shock, vibration, etc. from the second casing to the first casing is reduced. As a result, it is possible to effectively prevent damage to the device body inside the first housing and improve the maintainability of the disk device.

ことができる。When the cushioning material is a liquid having a specific gravity substantially equal to that of the first casing in the state where the apparatus main body is housed, the first casing is in a state of being floated at approximately the middle of the inside of the second casing. Becomes In this state, even if the second casing receives an impact from the outside, it is transmitted to the first casing via the liquid, so that the impact is dispersed and absorbed in the surrounding liquid, which reduces the impact. To be done. Furthermore, since the movement of the first casing inside the second casing is suppressed by the flow resistance of the liquid, the collision between the first casing and the second casing is prevented. As a result, it is possible to effectively prevent damage to the device main body inside the first housing and improve the maintainability of the disk device.

Even when a shock is applied, the shock is transmitted to the first housing through the liquid, so that the shock is dispersed and absorbed by the surrounding liquid, and is thereby reduced. Furthermore, since the movement of the first casing inside the second casing is suppressed by the flow resistance of the liquid, the collision between the first casing and the second casing is prevented. These effectively prevent damage to the device body inside the first housing,
