Figures 1 to 3 show a hardened cam as an example of the present invention. Figure 1 is a schematic cross-sectional view showing the distribution of residual stress in the cam, and Figure 2 is a shot peening process. FIG. 3 is a schematic diagram showing another example of the shot peening processing process, FIG. 4 is a front view schematically showing a conventional chill cam, and FIG. 5 is a schematic diagram showing a conventional chill cam. FIG. 3 is a schematic cross-sectional view showing the distribution of residual stress in a hardened cam. 1... Hardened cam, 2... Cam surface, 3... Stress residual portion caused by induction hardening, 4... Stress residual portion caused by shot peening,
5... Part to be ground, 6... Cam top part,
7...Frank part, 8...Shot peening machine, 9...Camshaft.
