Abstract

Provided is a structure including a sound absorption section provided in an air flow path on an exhaust side of a fan, traversing a joint portion between a first main housing and a second main housing. The sound absorption section has a double wall structure including an inner wall facing the air flow path and an outer wall spaced outward from the inner wall. A sound absorption member is interposed in a sound absorption chamber between the inner wall and the outer wall of the sound absorption section. A communication hole communicating with the air flow path and the sound absorption chamber is formed in the inner wall of the sound absorption section at a position away from the joint portion.
