In recent years, miniaturization of the reel body has become one of the important elements of the spinning reel for fishing in order to improve the fishing operability and portability.
However, when the reel body is downsized, the space inside the body becomes narrow. Therefore, the space for accommodating the components that constitute the spool reciprocating device, such as the interlocking gear and the slider, is also narrowed, and the diameter of the interlocking gear is reduced. As a result, the stroke of the slider of the spool reciprocating device is shortened, and it becomes impossible to secure a predetermined bobbin winding capacity.

The present invention was created in order to solve such problems, and it is an object of the present invention to provide a fishing spinning reel capable of avoiding deterioration of the function of the spool reciprocating device while reducing the size of the reel unit. And
