Patent number: 7866587Abstract: A drag adjusting mechanism for a dual-bearing reel comprises a drag adjusting lever, a cam mechanism, and a rotation restricting portion. The drag adjusting lever rotates about a spool shaft between a drag release position and a maximum drag position. The cam mechanism has a cam surface that converts rotation of the drag adjusting lever into axial movement of the drag mechanism along the axial direction of the spool shaft. The rotation restricting member is provided on the cam surface and regulates rotation of the drag adjusting lever to the drag release position. The rotation restricting member has a protrusion with an apex, a first slanted surface extending from the apex toward a first position corresponding to a drag release position, and a second slanted surface extending from the apex in the direction opposite to the drag release position. The angle of the first slanted surface is smaller than the angle of the second slanted surface.Type: GrantFiled: June 29, 2009Date of Patent: January 11, 2011Assignee: Shimano Inc.Inventors: Takeshi Ikuta, Kunio Takechi
