  • Publication number: 20190343104
    Abstract: Provided is a fishing reel having a pinion support structure. The fishing reel is configured such that a spool shaft and a pinion are spaced apart from each other without being in contact with each other, so that it is possible to prevent reduction in casting distance and noise generation during casting due to friction between the spool shaft and the pinion. The fishing reel includes: a spool shaft provided such that opposite ends thereof are mounted axially between opposite side covers, and including a main shaft and a pinion shaft; and a clutch means fitted over the pinion shaft and moved forward and backward in a longitudinal direction of the pinion shaft, and including a pinion which is provided with a stopper at a second end portion to be engaged with the fastening pin.

  • Patent number: 10264773
    Abstract: Provided is a drag release system of a reel, that system adjusting drag by rotation of a spool on the reel, more particularly, a drag release system that immediately adjusts drag of a spool to prevent cutting of a fishing line by immediately decreasing the drag of the spool when strong tension is applied to the spool during fishing, by forming a fitting hole perpendicular to the axis of a cylindrical driving shaft and forming slits at a sleeve fitted on the driving shaft to have a predetermined length in the longitudinal direction of the driving shaft and to correspond to the fitting hole so that a fixing pin fitted in the fitting hole through the slits prevents the sleeve from idling on the driving shaft and guides the sleeve when the drag is adjusted.
