<P>PROBLEM TO BE SOLVED: To provide an air damper capable of stably providing a desired characteristic with a simple constitution. Ž<P>SOLUTION: This air damper includes a cylinder for arranging an opening on the base end and closing the tip, and a reciprocateable piston inserted into the cylinder from the opening. The cylinder has a flow passage for making air flow to a space formed between the piston and the cylinder tip in the cylinder. The flow passage is formed so as to be gradually blocked up by the piston as the piston approaches the tip. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
