PURPOSE: An air sleeve for an air spring is provided to facilitate the heating by forming the diaper pattern on the outer surface, multiplying the surface area, and simultaneously facilitate the separation from the mold. CONSTITUTION: An air sleeve for an air spring has an air sleeve(5). The air sleeve comprises a first linear groove(11), and a second linear groove(12). The first linear groove and second linear groove are concavely formed on the outer surface. The second linear groove is extended in the direction having the constant angle between the first linear grooves. The air sleeve comprises the square convex part(13) formed in the part in which the first and second linear grooves are not formed. The convex part comprises the depression(14) which is concavely formed at the center of the convex part in order to reduce the surface area of the convex part. |
