A dual-driving one-way rotational device includes: a body part; a clutch bearing part configured to guide the rotation of the body part in one direction; a knob part configured to be rotated in one direction in the state of being connected to an object to be rotated or to prevent the body part from being rotated together when the object to be rotated and the clutch bearing part are rotated in the same direction; a manual rotation lever installed on the body part; and a power transmission shaft coupled to the knob part, and configured to transfer the power of a power source. The knob part includes a rotation portion and a head portion. A spiral is formed on the inner circumferences of the rotation portion and the head portion. The power transmission shaft has the outer circumference on which a spiral is formed.

A support structure for a fishing reel includes a first portion, a second portion, a first shaft bearing and a second shaft bearing arranged side by side in the axial direction along an axis between the outer circumferential surface of the first portion and the inner circumferential surface of the second portion, a spacer disposed between an inner race of the first shaft bearing and an inner race of the second shaft bearing, and a regulating member configured to restrict movement an outer race of the first shaft bearing or an outer race of the second shaft bearing, in a direction in which one of the outer race of the first shaft bearing or the outer race of the second shaft bearing is separated from the other of the outer race of the first shaft bearing or the outer race of the second shaft bearing.

The invention provides an electric fishing gear comprising a fishing reel, a handle, a motor and a motor speed control, the fishing reel can be removed to connect the handle, the fishing reel provides the lead power of the line by the motor, the motor speed control is used to adjust the speed of the motor in real time, to adjust the receiving speed of the fishing reel, the handle is set to provide electric power for the motor power device.

Provided is a magnetic fluid sealed bearing with which torque can be reduced without impairing a water and dust proof effect. A magnetic fluid sealed bearing according to the present disclosure includes a magnetic fluid retained by a ring-shaped magnet in an opening between an inner ring and an outer ring to seal a plurality of rolling members. The magnet is magnetized such that their magnetic poles point to an axial direction. The bearing further includes a ring-shaped outer polar plate and a ring-shaped inner polar plate sandwiching the ring-shaped magnet therebetween, one side of the polar plates being fixed to one of the inner ring and the outer ring, and the other side of the polar plates facing a clearance.

A fishing reel that may be used in connection with bowfishing is disclosed having a housing with a generally cylindrical first portion with an aperture disposed about a center top portion of the cylindrical first portion. The housing has a generally cylindrical second portion disposed about a bottom of the first portion. The second portion of the housing has an outer perimeter that is less than an outer perimeter of the first portion of the housing. A crank arm is disposed about a side of the housing, said crank arm having a mount that is disposed perpendicular to a longitudinal axis of the housing. A handle is disposed about a bottom of the second portion, said handle having a post disposed coaxial with a center of the aperture and a grip coupled to the post and disposed perpendicular to the post.

According to the present disclosure, in a fishing reel that comprises component members of various types arranged in a reel body, winds up a fishing line around a spool, and releases the fishing line that has been wound up around the spool, the component members are arranged in a contact state or a proximity state, the component members comprising different types of materials that are different in a raw material, and a corrosion member is attachably/detachably arranged on the component members in a conductive state, the corrosion member having a potential difference that is greater than the potential difference between the component members comprising the different types of materials.

The waterproof structure includes a reel body, a spool, a first abutting member, and a second abutting member. The first abutting member includes a first body portion and at least one first annular protrusion. The first body portion abuts with the reel body. The first annular protrusion protrudes from the first body portion. The second abutting member includes a second body portion and at least one second annular protrusion. The second body portion abuts with the spool and is adjacently disposed at a predetermined first waterproof gap from the first annular protrusion. The second annular protrusion protrudes from the second body portion and is adjacently disposed at a predetermined second gap from the first body portion. The first annular protrusion and the second annular protrusion are adjacently disposed with a predetermined second waterproof gap therebetween.

A fishing reel having easily selectable gears is disclosed. A gear assembly is disposed on the side of the reel opposite the crank handle, which has a gear ratio selector knob to easily and quickly change gear ratios to thereby change retrieval speeds.

A bottle-style reel for bow-fishing and the like provides a retriever bottle that is tipped out of the vertical plane defined by the crank axis and the rotation of interengaging wheels that grip the fishing line and push it into the retriever bottle. In this way the retriever mechanism of the interengaging wheels can be aligned with the bow grip for reduced torque and simplified mounting.
