PROBLEM TO BE SOLVED: To provide a sintered gear, heightening the fatigue strength and wear resistance of a tooth part by a method advantageous in cost, and a manufacturing method of the gear. SOLUTION: In this sintered gear 1, the carbonized quenched tooth flank has skin subjected to shot-peening, and the texture of a part 0.06 mm deep from the surface of the tooth flank is made as dense as hole percentage of 3% or less. This sintered gear 1 is manufactured by a method of peening the tooth flank with a shot whose particle diameter isϕ0.3 mm or less. COPYRIGHT: (C)2006,JPO&NCIPI
