Bridge pads type fretting fatigue test for shotpeened Ti-6Al-4V alloy were carried out to clarify fretting fatigue limits over 10^7 cycles.There were very small defferences between fretting fatigue strength at 10^7 cycles and at 10^8 cycles. Fretting fatigue limits were not clearly observed, because fretting fatigue still occurred even at 10^8 cycles. But fretting fatigue strength of shotpeened specimens were improved at 10^8 cycles as well as at 10^7 cycles.
