Drag force measuring device for spinning reels

In a spinning reel having a bailed rotor rotably mounted on a reel body, a spool pin rotatably, and axially slidably, mounted on said reel body, a spool carried on said spool pin for rotation therewith and being adapted for windingly receiving thereabout a fishing line responsive to rotation of said spool, a drag mechanism mounted on said reel body, and means operatively interconnecting said drag mechanism and said spool pin for applying a drag force to said spool, the improvement comprising a drag force measuring device comprising a measuring operation member for rotating said spool, a measuring spring member connecting said operation member and said spool whereby upon rotation of said operation member said spring is stressed to establish a torque corresponding to the drag force set by said drag mechanism, and indicating means for indicating in terms of the applied drag force the amount of relative rotation between said operation member and said spool before the same are jointly rotatable.
