Zusammenfassung:PURPOSE:To provide a prescribed collision load due to shot grains for an article to be processed, by installing a shot-grain feeding mechanism, a pressure sensor, etc., and continuously metering the shot-grains feeding state in shot peening. CONSTITUTION:A pressure sensor 1 is arranged in the vicinity of an article to be processed (gear) 4, and a shot-grain feeding mechanism 5 is positioned in the upper region. In a hopper 5a, shot grains each having a prescribed particle-size distribution are stored in a prescribed amount. The shot-grain supplied collides in a certain collision load with the root of the gear 4, which is provided with plastic deformation, and the fatigue strength of the root is improved markedly. While, the shot-grains are supplied towards the pressure sensor 1 arranged in the vicinity of the gear 4, and the collision load state due to the shot-grains which is received by the root of the gear 4 is metered by the sensor 1.
