This also acts as resistance to spool rotation, and such resistance to spool rotation has been a factor that reduces the flight distance during casting. Therefore, in order to solve such inconvenience, the following reel has been put to practical use or proposed. (A) The thread guide hole portion of the thread guide is divided into left and right during casting, but (B) the thread guide is disconnected from the screw shaft, but the thread is still inserted. During casting, it is pulled by the thread and freely moves to the left and right. (C) Thread guides, level wind mechanism with screw shaft, etc. are integrated and can be attached and detached at the front of the reel body. (For example, Japanese Patent Application No. 4-74321), (D) With the thread guide attached to the screw shaft, the thread guide is swingable around the axis of the screw shaft for clutch disengagement operation. When the thread guide is in a forward tilted position in conjunction with it, and the thread comes out of the cutout portion of the thread guide hole in the thread guide and is cast, the thread guide moves along the screw shaft (for example, , Jitsukai 60-15165 gazette), there were. The structure adopting the configurations (A) to (D) described above has a complicated structure and is liable to cause a failure. In (B) and (C), it is possible to prevent the spool from moving due to movement of the yarn guide tool during casting or the like.
