  • Publication number: 20180103627
    Abstract: A dual-bearing reel includes a reel body and a spool. The reel body includes a first body part, a second body part, and a thumb rest. The spool is rotatably disposed between the first body part and the second body part. The spool includes a bobbin trunk, a first flange, and a second flange. The first flange is on a first body part side of the bobbin trunk, and has a smaller diameter than the first body part. The second flange is on a second body part side of the bobbin trunk, and has a smaller diameter than the second body part. The first body part includes a cutout part on an outer edge of the first body part. The cutout part is adjacent to the thumb rest and to an outer edge of the first flange of the spool.

  • Patent number: 9854791
    Abstract: A dual-bearing reel includes a reel unit, a handle, a spool, and a spool brake. The handle is rotatably mounted to the reel unit. The spool is in the reel unit, and rotates in conjunction with a rotation of the handle. The spool includes a bobbin trunk, a first flange, and a second flange. The first flange is on a first end of the bobbin trunk, and the second flange is on a second end of the bobbin trunk. The bobbin trunk includes a bored tubular part and a non-bored tubular part. The bored tubular part includes at least one hole, and the non-bored tubular part is integrated with the bored tubular part. The spool brake is in the reel unit, and can apply a braking force to the spool by applying a magnetic force to at least the non-bored tubular part.

  • Publication number: 20170280698
    Abstract: A handle is rotatably attached to a first reel body. A second reel body has a cylindrical shape, and is an interval apart from the first reel body in an axial direction. A spool is disposed between the first reel body and the second reel body. A mount includes a mount surface facing in a first direction to contact the fishing rod when the dual-bearing reel is mounted to the fishing rod. The second reel body includes an outer peripheral surface and an outer lateral surface. The outer lateral surface faces outward in the axial direction, and the outer peripheral surface of the second reel body has a width narrower towards a first directional end of the second reel body than towards a second directional end of the second reel body. The second directional end is opposite to the first direction end.
