Using the fixed point method, we prove the generalized Hyers--Ulam--Rassias stability of Cauchy functional equation n Felbin s type normed linear spaces. The concept of Hyers-Ulam-Rassias stability originated from Th. M. Rassias stability theorem that appeared in his paper: On the stability of the linear mapping in Banach spaces, Proc. Amer. Math. Soc. f 72 (1978), 297--300.
