<P>PROBLEM TO BE SOLVED: To provide an air diffusion device which can prevent an elastic porous body from shifting its position and creasing by air diffusion operation. <P>SOLUTION: In the air diffusion device, a plate-like support 10 includes a plurality of independent protrusions 14 formed along a periphery thereof, the elastic porous body 20 has a plurality of independent fixed holes 22 formed along a periphery thereof so as to penetrate in a thickness direction, and a frame 30 has a plurality of independent recesses 34 formed along a periphery thereof. The protrusions 13 of the support 10 penetrate the fixed holes 22 of the elastic porous body 20 to be fitted into the recesses 34 of the frame 30, whereby they are integrated with each other. <P>COPYRIGHT: (C)2013,JPO&INPIT |
