Abstract

A dual-bearing reel includes a reel body, a spool and a waterproof member. The reel body includes a first side plate and a second side plate. The spool includes a bobbin trunk and a first flange. The bobbin trunk is rotatably disposed between the first side plate and the second side plate. The first flange is provided on a first side plate-side end of the bobbin trunk and has a larger diameter than the bobbin trunk. The waterproof member has an annular shape and is disposed in a first side plate-side position in the reel body. Additionally, the first flange includes a rib having an annular shape. The rib extends axially outward from the first flange and has a smaller diameter than an outermost diameter part of the first flange. The waterproof member is disposed in adjacent opposition to an inner peripheral surface of the rib of the first flange.

First claim

What is claimed is:

1. A dual-bearing reel comprising:
a reel body including a first side plate and a second side plate, the second side plate disposed at an interval from the first side plate in an axial direction;
a spool rotatably disposed between the first side plate and the second side plate, the spool including a bobbin trunk, a first flange and a second flange, a fishing line to be wound about an outer periphery of the bobbin trunk, the first flange provided on a first side plate-side end of the bobbin trunk, the first flange having a larger diameter than the bobbin trunk, the second flange provided on a second side plate-side end of the bobbin trunk, the second flange having a larger diameter than the bobbin trunk; and
a waterproof member having an annular shape, the waterproof member disposed in a first side plate-side position in the reel body, wherein
the first flange includes a rib having an annular shape, the rib extending axially outward from the first flange, the rib having a smaller diameter than an outermost diameter part of the first flange, and
the waterproof member is disposed in adjacent opposition to an inner peripheral surface of the rib of the first flange, wherein
the reel body further includes a boss, the boss protruding from a first side plate-side toward a bobbin trunk-side, the boss disposed in an inner peripheral part of the first flange, and
the waterproof member is attached to an outer periphery of the boss.

2. The dual-bearing reel according to claim 1 , wherein the waterproof member has a disc shape, the waterproof member including a first outer peripheral part and a second outer peripheral part, the first outer peripheral part disposed in adjacent opposition to the inner peripheral surface of the rib of the first flange, the second outer peripheral part having a smaller outer diameter than the first outer peripheral part, the second outer peripheral part provided axially outward of the first outer peripheral part.

3. The dual-bearing reel according to claim 1 , wherein
the waterproof member is made of an elastic material, the waterproof member configured to inhibit water from intruding between the inner peripheral part of the first flange and an outer peripheral part of the boss.

4. The dual-bearing reel according to claim 1 , wherein
the first flange of the spool further includes at least one protrusion having an annular shape, the at least one protrusion protruding axially outward from the first flange on an inner peripheral side of the rib of the first flange, and
the at least one protrusion has a shorter axial length than the rib of the first flange.

5. The dual-bearing reel according to claim 1 , wherein the inner peripheral surface of the rib is a taper surface slanting such that a diameter of the inner peripheral surface of the rib gradually increases with axially outward extension of the inner peripheral surface of the rib.

6. The dual-bearing reel according to claim 1 , wherein an outer peripheral surface of the rib is a taper surface slanting such that a diameter of the outer peripheral surface of the rib gradually reduces with axially outward extension of the outer peripheral surface of the rib.

7. The dual-bearing reel according to claim 1 , further comprising:
a bearing member that supports an end of a spool shaft of the spool.

8. A dual-bearing reel comprising:
a reel body including a first side plate and a second side plate, the second side plate disposed at an interval from the first side plate in an axial direction;
a spool rotatably disposed between the first side plate and the second side plate, the spool including a bobbin trunk, a first flange and a second flange, a fishing line to be wound about an outer periphery of the bobbin trunk, the first flange provided on a first side plate-side end of the bobbin trunk, the first flange having a larger diameter than the bobbin trunk, the second flange provided on a second side plate-side end of the bobbin trunk, the second flange having a larger diameter than the bobbin trunk; and
a waterproof member having an annular shape, the waterproof member disposed in a first side plate-side position in the reel body, wherein
the first flange includes a rib having an annular shape, the rib extending axially outward from the first flange, the rib having a smaller diameter than an outermost diameter part of the first flange, and
the waterproof member is disposed in adjacent opposition to an inner peripheral surface of the rib of the first flange, wherein
the first flange of the spool further includes at least one protrusion having an annular shape, the at least one protrusion protruding axially outward from the first flange on an inner peripheral side of the rib of the first flange, and
the at least one protrusion has a shorter axial length than the rib of the first flange.
