Using three kinds of bridge type pads, which foot height is different, fretting fatigue tests were performed in order to clarify the parameter which fretting fatigue strengths obtained by different pad size could be evaluated uniformly. Fretting fatigue strength was 170 MPa for 3.0 mm of pad foot height and 150 MPa for 1.5 mm and 0.6 mm pad. Since relative slip amount, which was measured by specially made relative slip sensor, and friction coefficient were different each other, the fact that fretting fatigue strength was divided into two groups on the S-N diagram could not be explained. Taking local stress, which was estimated by stress distribution near contact edge measured by multi-element micro stain gauge, into consideration, fretting fatigue limit coincided with each other.
