Abstract:
A preset fishing line-tension measuring device comprising:a pair of spaced-apart-fishing line guides; a tension sensor for sensing a fishing line tension, the tension line sensor being disposed between the fishing line guides so as to increase the length of path of a fishing line; a movable member for supporting the tension sensor and being reciprocally and linearly moved in a first direction when the fishing line tension is given on the movable member through the tension sensor; a first spring for providing a spring force on the movable member so as to move the movable member in a second direction opposite to the first direction; a display part including a scale board and a pointer driver, the pointer driver being rotated in a third direction and displaying the fishing line tension as a rotation angle of the pointer driver in the third direction thereof on the scale board; and a gear mechanism for converting and amplifying the linear movement of the movable_member into a rotary movement of the pointer driver, the gear mechanism including a rack being formed in the movable member, a pinion being meshed with the rack, a first gear being integrally connected with the pinion, and a second gear being rotatable in unison with the pointer driver, wherein the second gear rotating in a fourth direction when the movable member is moved in the first direction as the fishing line tension increases, the first gear having a radius of rotation larger than radiuses of rotation of the pinion and the second gear such that the pointer driver is rotated in the third direction in an amplified manner by the gear mechanism.
