Fatigue crack growth inhibiting method and the fatigue crack growth inhibiting metal member of a metal member

The method of the fatigue crack growth inhibiting metal member, the repeated tensile metal member body stress occurs fatigue cracks acts (12), laterally with respect to the crack direction of the distal end portion of the fatigue crack (14) (14a) hole (18) is formed, the metal member body (12) higher rigidity than, and press-fit hole (18) than the outer large press-fitting body (20) in the hole (18), the tip of the fatigue crack (14) ( to 14a), to apply a compressive stress from the side (C) with respect to the crack direction
