PROBLEM TO BE SOLVED: To avoid a damage and deformation by a collision by setting a plurality of sheets of HDD main bodies each having a hold part and an engaging means, and a supporting means having a plurality of slots formed in parallel via a predetermined distance in a longitudinal direction opposite to both side faces, an engagement part and damper parts formed close to an upper end part of each side face of a frame and close to a lower end part of a groove part. SOLUTION: Vent holes 25 of a long rectangle in an up-down direction are formed via a constant distance in a lateral direction by, for example, punching a supporting plate 21. Rise walls 26 and 27 are formed by lancing inward along both ends of the vent hole 25 and a slot 28 where an HDD unit is to be inserted is formed between the rise walls 26 and 27. A first groove part 29 to be an engagement part is formed at least to an upper edge of the supporting plate 21. The engagement part is a groove part of a U-shaped section direction inside. A second groove part 30 is formed to a lower edge part. A mount part is formed to be directed outside via a flat part 21a bent inward.
