Patent number: 7290727Abstract: In a first embodiment of the present invention, a fishing line latching member can be returned from the fishing line releasable state (clutch OFF) to the fishing line windable state (clutch ON) simply by operating a return operation member, without rotatably operating the handle as in a conventional manner. This enables the user to respond promptly even when he/she gets a bite immediately after casting the fishing line. Furthermore, it also allows the user to use a finger of his/her hand holding the fishing rod to perform an operation for removing slack of the fishing line by using the return operation member.Type: GrantFiled: March 19, 2007Date of Patent: November 6, 2007Assignee: Daiwa Seiko, Inc.Inventor: Kazuyuki Matsuda
