A spool for a fishing reel attached to a reel body of the fishing reel includes a spool body, a spool ring, a fixing ring and a first regulating part. The spool body has a bobbin trunk, an annular flange extending from the bobbin trunk in a radially outward direction that intersects the spool axis, and a tubular connecting portion extending from the flange. The spool ring surrounds an outer peripheral edge of the flange, and is attached to the flange so as to be separable. The fixing ring is attached to the spool body via the tubular connecting portion so as to be separable and is configured to fix the spool ring against the flange from the front direction. The first regulating part regulates relative movement of the fixing ring with respect to the spool body and is detachably attached to the tubular connecting portion.本發明之課題在於將捲筒環任意地卸除。 本發明提供一種釣具用捲線器之捲筒5，其係組合於將釣線向前方陸續送出之釣具用捲線器之捲線器本體，並且伴隨著把手之旋轉操作而沿著捲筒軸線前後移動之捲筒，且具備：捲筒本體60，其具有捲繞釣線之捲線主體部65、自捲線主體部之前端部朝向與捲筒軸線交叉之徑向之外側延伸的環狀之法蘭部67、及自法蘭部朝向前方延伸之連結筒部68；捲筒環61，其相對於法蘭部能夠自前方分離地組合於該法蘭部；及固定環62，其經由連結筒部相對於捲筒本體能夠自前方分離地組合於該捲筒本體，且將捲筒環自前方壓入法蘭部；於連結筒部，限制固定環相對於捲筒本體之相對移動之第1限制部120相對於連結筒部能夠脫離地安裝。
