PURPOSE:To facilitate fixing of a rack casing to the chassis by fixing resilient members to the upper and lower inner metals then fastening the outer metal and pressure deforming. CONSTITUTION:An insulator 7 is comprised of an outer metal 14, upper inner metal 10, lower inner metal 11 and resilient members provided between them. The lower resilient member 13 is projected by the distance (L) from the lower face of the outer metal 14 and when fixed to the chassis through a screw 15, the resilient members 12, 13 will pressure deform. The upper and lower inner metals 10, 11 are held by the rack casing together with the resilient members 12, 13 to fix the insulator 7 by simply fastening the outer metal 14 through a screw 14. Since circular resilient member is not employed, fluctuation of assembly is eliminated. |
