Fatique limit of rotational bending of friction welded joint of carbon steel (S45C) and austenitic stainless steel (SUS304) was examined, and compared whith fatique limits of respective the base material specimen and discussed. Moreover, change of metallic texture of boundary of friction weld was analyzed and observed with energey dispersive X-ray microanalyzer. Obtained result were summarized as follows : 1) Fatique limit of friction welded joint of machine structural carbon steel (S45C) exceeds the fatique limit of the base material specimens. 2) Fatique limit of friction welded joint of dissimilar metals (S45C/SUS304) shows intermediate value of both the base material specimen, and it depend upon the material with lower fatique limit. 3) In the friction welded part of SUS304 and S45C the presence of formation layer containing elemental Cr and very small amount of elemental Ni which were diffused from SUS304,was confirmed. 3) In the central part of this formation layer, S45C was confirmed to show convexity.
