A spinning reel configured such that when a rotor rotates in a line-winding direction, the attitude of a bail arm is switched from a line-releasing attitude to a line-winding attitude. The spinning reel includes a reel body and a bail reversing mechanism. The bail reversing mechanism includes an engagement member and a switching member. The reel body has an accommodation recess for accommodating at least a portion of the switching member. The engagement member engages the bail arm. The switching member is disposed on the reel body. The switching member switches the attitude of the bail arm via the engagement member by contact with the engagement member.本發明係提供一種能防止切換構件之變形之紡車式捲線器。本紡車式捲線器10構成為於轉子16向線捲取方向LW旋轉之情形時，能使導環臂18之姿勢自線捲出姿勢向線捲取姿勢切換。紡車式捲線器10具備捲線器本體12、及導環反轉機構20。導環反轉機構20具有卡合構件60、及切換構件64。捲線器本體12具有收容切換構件64之至少一部分之收容凹部12g。卡合構件60卡合於導環臂18。切換構件64設置於捲線器本體12。切換構件64藉由與卡合構件60之接觸，從而經由卡合構件60切換導環臂18之姿勢。
