Abstract

PURPOSE: To effectively absorb a noise generated from an impeller, by interposing a noise silencing material between a casing and partitioning part which form a flow line of a small vortex flow blower or the like.
CONSTITUTION: A casing 1 and partitioning part 14 forming a flow line 6 are formed by separate members respectively and combined through a noise absorbing material 15 interposed between the both of these members. At the time of rotation of an impeller 4, a noise, generated in a place especially in the vicinity of the partitioning part 14, can be absorbed by the noise absorbing material 15 to effectively absorb the noise.
