发明名称 Fishing reel with a line tension measuring device
摘要 The invention concerns a fishing reel including a line tension measuring device which is capable of adjusting a drag force properly. In the line tension measuring device, magnetostrictive magnetic thin bands are bonded to the outer periphery of a spool shaft, a coil is provided in such a manner that it is opposed to the magnetic thin bands, variations in the permeabilities of the respective magnetostrictive thin bands caused by variations in the tension of a fishline are measured as variations in the induced voltage of the coil, the values of the measured variations are converted to the line tensions, and the line tensions are displayed on the display portion of the line tension measuring device.
