Influence of alignment error and manufacturing error in face gear engagement is reported. Although many face gears are used for the fishing spinning reel, the time required for adjustment during the assembling of a reel has been increasing when the tooth flank is not modified (1). According to this report, it was shown when a suitable tooth flank modification was applied to a manufactured tooth flank by a pinion gear cutter, the influence of alignment error decreased. There are three types of alignment error "Height error", "Offset error" and "Difference error". In a mass production, however, it is also necessary to take into account manufacturing error of a pinion gear and a face gear as some factors which affect the rotation feeling of a reel in addition to alignment error. In this research, those factors of manufacturing error were considered in the assembly error and the factor effect analysis was conducted by 3D simulation. The problem when the modified tooth flank was adopted to real products was verified in advance.
