Abstract
A fishline tension measuring device used in a fishing reel measures tensile forces applied to a fishline. The fishing reel fishline tension measuring device, when tension is applied to a fishline of a fishing reel, detects a load applied to a bearing which is transmitted from the fishline through a spool shaft, and detects the tension applied to the fishline according to a force transmission relationship between the fishline tension and the load. The device includes a bearing support member which journals the spool shaft and can be flexed according to the load, an electrostatic capacitance sensor which detects the flection of the bearing support member as a variation in the electrostatic capacitance from the displacement of at least one of electrodes disposed in the bearing support member, and tension detector which detects the fishline tension from the output of the electrostatic capacitance sensor according to the force transmission relationship.
