It is an object of the present invention to reduce the weight of a support member and inhibit cost increase in a spinning reel fishing line guide mechanism. A spinning reel fishing line guide mechanism for guiding a fishing line onto a spool includes a support member and a fixation member. The spinning reel fishing line guide mechanism is attached to a tip of a rotor arm and is pivotable between a fishing-line guide position and a fishing-line release position. The support member is attached pivotably to the tip of the rotor arm. The support member includes an outer member made of metal and an inner member made of synthetic resin. The inner member is fixed to an inner surface of the outer member.對於紡車式捲線器的釣線導引機構,可達成支撐構件的輕量化並且抑制成本的增加。第1導環支撐構件(40),是可擺動自如地裝設於第1轉子臂(31)的先端。第1導環支撐構件,是具有:金屬製的外側構件(91)、及合成樹脂製的內側構件(92)。內側構件(92),是被固定於外側構件(91)的內側面。31‧‧‧第1轉子臂31a‧‧‧螺孔40‧‧‧第1導環支撐構件40a‧‧‧第1旋轉支撐部40b‧‧‧第1臂部40c‧‧‧第1裝設部41‧‧‧線形滾子43‧‧‧導環44‧‧‧導環臂45‧‧‧固定軸46‧‧‧固定軸蓋90‧‧‧固定構件90a‧‧‧頭部90b‧‧‧螺紋軸91‧‧‧外側構件91a‧‧‧凹部91b‧‧‧第1貫通孔91c‧‧‧螺紋孔92‧‧‧內側構件92a‧‧‧第1部分92b‧‧‧第2部分92c‧‧‧第2貫通孔92d‧‧‧第3貫通孔92g‧‧‧鍃孔凹部93‧‧‧螺栓構件93a‧‧‧頭部93b‧‧‧螺紋軸
