Since the frictional resistance between the fishing line 32 and the front flange portion 8 'is reduced, breakage of the fishing line 32 can be reduced. The incorporation of the front flange 8 'into the front of the spool 8 is improved. The use of the bearing 33 formed of a ball bearing with a shield prevents foreign matter from entering and provides smooth rotation.

When the transmission for a fishing reel is constructed as described above, the winding speed can be easily switched between high and low according to the type of fishing, and the high-speed driving gear 4 and the low-speed driving gear 4 'are connected to the reel body. 1 rotating shaft cylinder 2 in a limited space
Also, since the reels can be arranged on the left and right sides of the spool shaft 7 in a well-balanced manner, it is possible to equip the transmission devices with good balance on the left and right sides of the handle shaft 13 without increasing the size of the entire reel. Good spinning reel for fishing can be provided.

In the above description, the fishing reel has been described as a fishing spinning reel, but it may be implemented on other types of reels.
