Abstract

PURPOSE: To reduce the noise by providing spaces between an outer frame and a casing, also many holes at the positions corresponding to those spaces in the casing.
CONSTITUTION: Spaces 7W9 are formed between an outer frame 1 and a casing 6 and may holes are also formed at the positions corresponding to those spaces 7W9 in the casing 6. Hereby, noise generated from a fan 5 is reduced by the cooperative action of holes 11 with the spaces 7W9, thus achieving a low level noise.
