Patent number: 10966418Abstract: A fishing reel includes a reel body that supports a spool so as to be rotatable, and a spool brake. The spool brake includes an operator and a braking force adjuster. The operator is configured to be rotatable and axially immovable with respect to the reel body, and has an internal space extending in an axial direction and opening axially outwardly. The braking force adjuster is disposed in the internal space and is configured to be axially movable with respect to the reel body in conjunction with rotation of the operator to adjust a braking force of the spool.Type: GrantFiled: June 21, 2019Date of Patent: April 6, 2021Assignee: Shimano Inc.Inventors: Hiroki Oogose, Akira Niitsuma, Motohiro Niitsuma

Patent number: 10881089Abstract: A spinning reel for casting fishing line includes a handle rotatably, a spool shaft, a spool, a rotor and a drainage hole. The spool shaft moves back and forth in accordance with rotation of the handle. The spool includes a bobbin trunk and a skirt portion in a rear portion of the bobbin trunk and has a larger diameter than the external diameter of the bobbin trunk. The rotor rotates has a wall portion with a smaller diameter than an external diameter of the skirt portion and through which the spool shaft penetrates, the rotor further including a first cylindrical portion protruding from the wall portion and at least part of which overlaps the skirt portion, and a second cylindrical portion protruding from the wall portion. The drainage hole passes from an interior to an exterior of the first cylindrical portion.Type: GrantFiled: August 13, 2019Date of Patent: January 5, 2021Assignee: Shimano Inc.Inventors: Koji Ochiai, Motohiro Niitsuma

Patent number: 10834910Abstract: A dual-bearing reel is provided that basically includes a reel main body, a spool, a clutch operating member and a first barrier portion. The reel main body has a first side plate and a second side plate. The second side plate is disposed at a distance from the first side plate in an axial direction. The clutch operating member is movably supported on the reel main body in a vertical direction between the first side plate and the second side plate behind the spool. The clutch operating member switches between a transmitting and disconnecting of a rotational force to the spool. The first barrier portion is provided on one of the clutch operating member and the reel main body. The first barrier portion prevents the fishing line from entering between the clutch operating member and the first side plate of the reel main body.Type: GrantFiled: July 5, 2018Date of Patent: November 17, 2020Assignees: Shimano Inc., SHUMANO COMPONENTS (MALAYSIA) SDN. BHD.Inventors: Baihaki Bin Sabtu, Abu Supian Bin Ahmad, Mohd Syamsul Johary Bin Ismail, Keigo Kitajima, Motohiro Niitsuma, Ami Higuchi

Patent number: 10765096Abstract: A dual-bearing reel includes a reel body, a cover member and a casting control mechanism. The cover member is disposed to cover the reel body from a first side plate side, and includes a cover part, a bulging part and a first boss part. The cover part is located outside a first side plate of a reel body of the dual-bearing reel in an axial direction. The bulging part bulges outward from the cover part in the axial direction. The first boss part has a shape protruding outward from the bulging part in the axial direction, and causes a spool shaft to be inserted therethrough. The casting control mechanism includes an operating member that is attached to the first boss part so as to be movable in the axial direction and protrudes at part of an outer periphery thereof from the bulging part as seen in the axial direction.Type: GrantFiled: November 2, 2017Date of Patent: September 8, 2020Assignee: SHIMANO INC.Inventors: Kunio Takechi, Youhei Toake, Motohiro Niitsuma

Patent number: 10588303Abstract: A dual-bearing reel includes a spool, a spool shaft, a spool supporting portion, a reel body, and a rotating member. The rotating member is disposed to be capable of rotating between a first position in which the spool supporting portion can be removed from the reel body and a second position in which the spool supporting portion cannot be removed from the reel body. In the first position the radially outside portion of the rotating member is disposed spaced apart from the reel body in at least one of a radial direction and an axial direction. In the second position the radially outside portion is disposed on the inside of the outer surface of the body portion in the radial direction, when viewing the rotating member from the outside in the axial direction.Type: GrantFiled: October 3, 2018Date of Patent: March 17, 2020Assignee: Shimano Inc.Inventors: Hiroki Oogose, Motohiro Niitsuma

Patent number: 10470448Abstract: 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.Type: GrantFiled: August 29, 2017Date of Patent: November 12, 2019Assignee: SHIMANO INC.Inventors: Kunio Takechi, Takeshi Ikuta, Youhei Toake, Motohiro Niitsuma

Patent number: 10327433Abstract: 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.Type: GrantFiled: January 24, 2017Date of Patent: June 25, 2019Assignee: SHIMANO INC.Inventors: Kunio Takechi, Motohiro Niitsuma
