Air spring has the advantages to be nearly constant in natural frequency inspite of load change, and to be able to control height level. Half-long taper spring has the advantages to function as well link as spring. Thus to utilize two type spring's advantages, half-long taper spring and air spring are combined and used. In this study, the theory to calculate the characteristics in combination is developed.
