Abstract
This invention provides an air bladder that can increase the force with which it presses on the user's body parts. [Solution] The air bag 30 comprises a first bag portion 41 having an inflatable and deflated air chamber 51 and an extension portion 53 extending from the air chamber 51, and a second bag portion 42 having an inflatable and deflated air chamber 52 and an extension portion 54 extending from the air chamber 52. When the air chamber 51 of the first bag portion 41 and the air chamber 52 of the second bag portion 42 are stacked on top of each other, the extension portion 53 of the first bag portion 41 is connected to the extension portion 54 of the second bag portion 42.
