The present invention provides an inner tube of a new airmatic shock absorber. An airmatic shock absorber applied to a vehicle absorbs and attenuates vibration energy in a vertical direction to prevent the vibration from directly being transferred to a chassis. The structure of a tire cord, which is injected and inserted into a space between an inner rubber layer and an outer rubber layer of the inner tube installed to cover the exterior of the cylinder tube, is improved to prevent the inner tube from easily being broken due to tensile force, thereby remarkably improving durability. The inner tube is installed inside a damper tube positioned outside to form an airmatic shock absorber in such a manner as to cover the exterior of the cylinder tube to protect the cylinder tube positioned at the center. In the inner tube of the airmatic shock absorber having the structure where the tire cord is injected and inserted into the space between the inner rubber layer and the outer rubber layers, the tire cord forming the inner tube has a structure where a diamond shaped protrusion is continuously formed vertically and transversely such that the tire is not easily broken even when tensile force is applied.;COPYRIGHT KIPO 2016
