Since one can make a manufacturing process short if a sintered material is applied to parts with complex configurations, reductions in production costs may be expected. Therefore, a gear made by steel powder sintering will be useful for a power transmission gear in automobile when the gear can be burnished using a worm-shaped tool to improve a tooth profile and a surface roughness. In the present study, sintered alloy steel was investigated using a two rollers contact fatigue testing machine to obtain a basic data for a design of gear tooth strength. The allowable surface durability strength of sintered alloy steel was lower than about half that of a melted produced steel (general structure steel). However; it is estimated that a sintered alloy steel gear will sufficiently be applicable to an automobile transmission if its application is limited to a range of a low load carrying capability.
