Granted: 1990-08-09
Abstract: The reel comprises a rotary frame supported rotatably to a reel body, and a spool supported on a shaft. A drage mechanism applies a resistance against rotation of the spool. A changeover control mechaism changes over the drage mechanism between an operating state in which the spool is subjected to a rotational resistance applied by the drage mechanism and an operation releasing state in which the operating state of the drag mechanism is released to enable the spool to be freely rotatable. A return mechanism, when the drag mechanism is released from the operating state, automatically restores the changeover control mechanism from a condition causing the drag mechaism to occupy the operation releasing state to a condition causing the drag mechanism to occupy the operating state following rotation of the rotary frame.
