PROBLEM TO BE SOLVED: To reduce the weight of a lower case, to provide a shape with a high degree of freedom and to suppress deformation in sidewall parts after being molded. SOLUTION: The lower case 30 comprises a front plate part 54, a rear plate part 32, a left side plate part 31L, a right side plate part 31R, and a bottom part 33 which are integrally formed with resin, and is formed like an approximately rectangle dish in plane view. An upper unit 10 is mounted on an upper opened portion of the lower case 30. Respective upper parts of the left side plate part 31L and the right side plate part 31R form collar parts 53L, 53R respectively extended to the outside of a right-and-left direction along a back-and-forth direction. The front and rear parts of the collar parts 53L, 53R respectively form flange parts 40A to 40D extended so as to be further protruded outward. An attachment part 41 and a notch part 42 are respectively integrally formed on each flange part 40 and functioned also as a mounting part at the time of rack mounting. COPYRIGHT: (C)2008,JPO&INPIT
