Abstract: A brake operation structure is mounted on a reel unit, and adjusts a braking force applied to a spool. This brake operation structure includes a mounting tube, an operation knob, and a screw member. The mounting tube is formed to project from the reel unit. The operation knob is formed in a closed-end tubular shape to accommodate the mounting tube. The screw member has two male threaded portions that have a tubular shape when coupled to one another. The operation knob is pivotably retained to the mounting tube when the screw member engages an outer peripheral portion of the mounting tube and an inner peripheral portion of the operation knob. The operation knob is prevented from falling off from the mounting tube, while allowing the operation knob to pivot stably relative to the mounting unit.

Abstract: Simple configuration in a low-gear-ratio type oscillating mechanism for realizing at high transmission efficiency improved lay in the line windings. Spinning reel oscillating mechanism (6), a mechanism that reciprocates the spool (12) in cooperation with rotation of handle (1), is furnished with gear piece (21) and slider (22). The gear piece rotates cooperatively with handle rotation, and is a component on whose one lateral face first and second cam portions (21a), (21b) are formed rim-wise. The slider is attached, immovably in the spool axial direction, at its tip to the rearward end of a spool shaft 20 for the spool, and has: a first cam engager (22a) that extends in a direction intersecting the spool shaft and engages with the first cam, and a second cam engager (22b) that extends in the same direction as the first cam engager and engages with the second cam; and is for reciprocating in the spool axial direction by engagement with either the two cams or the two cam engagers.
