Abstract

Fishing reels are required to have functions such as design, drag performance, and there is a particularly high demand for gear feeling (fishing reel sensation). To achieve smooth fishing reel sensation, we have developed "micro module gear", "HAGANE gear", and "measuring device for fishing reel sensation". In "micro module gear", we proposed a design method that improves the fishing reel sensation without depending on the tooth surface accuracy by elucidates the relationship between transmission error and the tactile sensation. In "HAGANE gear", we established technologies of precision cold forging, mold manufacturing, and measurement for face gear of reels that require micro meter level accuracy. In "measuring device for fishing reel sensation", it has become possible to quantitatively determine the fishing reel sensation instead of sensory human evaluation.
