摘要
A crack-propagation preventing structure that can suppress or prevent the propagation of cracks (2) that would be generated in a metal component (1) or that have been generated in a metal component (1) is provided. The crack-propagation preventing structure includes a point dimple (4) formed by pressing a rigid sphere (3) of a rigid body at an appropriate position on the surface of a metal component, which is subjected to crack-propagation prevention processing.
