A spinning type fishing reel includes a rotating member disposed rotatably within a reel body, a sliding member disposed movably within the body and connected fixedly to a reciprocating shaft, and a swing rod interconnecting the rotating member and the sliding member. When a handle is actuated to rotate the rotating member, the swing rod swings to reciprocate the sliding member and the reciprocating shaft. Accordingly, when a fishline is wound on the spool, the number of the turns of the fishline wound during a forward travel of the reciprocating shaft is different from that wound during a reverse travel of the reciprocating shaft, thereby resulting in a quite even distribution of the fishline on the spool.
