<P>PROBLEM TO BE SOLVED: To suppress the occurrence of noise at a suction hole peripheral part while sufficiently securing a curvature of a bell-mouth structure at the suction hole peripheral part. <P>SOLUTION: This air blowing device 1 includes: a suction means 9 for sucking air; a cover member 5 formed so that the suction hole 5a for guiding air therein faces the suction means 9; and a main body case 3 in which the suction means 9 is stored, having an guiding passage 20 formed therein for guiding the air sucked by the suction means 9 to the outside. The peripheral part of the suction hole 5a is formed in a bell-mouth structure forming a convex part from the surface, and a partitioning member is provided on the back surface of the convex part for partitioning a space formed between the back surface of the convex part and the suction means 9 by the bell-mouth structure. <P>COPYRIGHT: (C)2007,JPO&INPIT |
