  • Patent number: 10477849
    Abstract: A dual-bearing reel includes a handle, a spool, a spool shaft, a clutch mechanism, a pinion gear, and an elastic member. The spool shaft is connected to the spool to be integrally rotatable and has a first abutting portion. The pinion gear has a second abutting portion to abut the first abutting portion in the axial direction in the inner circumferential portion thereof, and can move in the axial direction between a coupled position, in which the pinion gear is connected to the spool shaft so as to be integrally rotatable, and a decoupled position, in which the connection is disconnected. When the pinion gear is in the coupled position, the elastic member contacts the distal end of the pinion gear and biases the first abutting portion and the second abutting portion in directions away from each other.

    Abstract: The object of this invention is to mechanically jig a fish lure with a bait casting reel without using the fishing rod to jig the lure. Normally to jig a fish lure one must move the fishing rod either vertically, horizontally, or jerk the fishing line by hand. The jigging action of this bait cast reel (how rapid and how long in distance the jig will travel) will determine the desired intensity and resonance of the rattle used in the lure to attract fish. A jigging action in this fishing reel is accomplished by simply cranking the reel crank 14 on the jig reel.

The bait reel equipped with a turning dial has a dial for spooling connected by the handle axle and the combination of gears. Therefore, it enables the user to manually fine-tune the revolution of the spool, makes the structure of the reel simple even when the turning dial is added by making the guide support add the turning dial to the handle axle so the fishing line can be smoothly and stably wound on or released from the spool, and makes it easy to change and maintain the turning dial by fixing the turning dial to the side cover located, with the possibility of detaching and re-attaching, on the opposite side of the handle.

    Abstract: A master gear includes a shaft made of an aluminum alloy, a gear portion, and an annular member made of stainless steel alloy. The shaft is screwed onto a handle shaft, a gear portion that is integrally formed on the outer periphery of the shaft. The shaft is supported by the reel unit at rotational support portions via bearings and has female threaded portions on its ends such that the handle is screwed to one of the female threaded portions. The gear portion is arranged on an outer periphery of the shaft portion between the rotational support portions, and meshes with a pinion gear. The annular portion is mounted to the outer periphery of the shaft such that at least part of the annular member is disposed not between the rotational support portions. With this structure, it is easy to remove bearings from a master gear of a spinning reel.

  • Patent number: 6702214
    Abstract: A power transmission mechanism is for transmitting power from a handle of a spinning reel to an oscillating mechanism, and includes a pinion gear, a dual-stepped gear, and a driven gear. The pinion gear rotates in cooperation with rotation of the handle. The dual-stepped gear has a larger-diameter gear that is a helical-tooth gear and meshes with the pinion gear, and a smaller-diameter gear that is arranged coaxially with the larger-diameter gear and is formed unitarily with the larger-diameter gear. The smaller-diameter gear is a straight-tooth gear or a helical gear whose orientation is substantially the same as an orientation of the larger gear. The driven gear meshes with the smaller-diameter gear to rotate the oscillating mechanism. In a power transmission device in a fishing reel, manufacturing cost is reduced while suppressing noise.

  • Patent number: 6626385
    Abstract: The invention is to offer a spinning reel for fishing, in which a handle can be replaced left and right, and an offset amount of a spool shaft and a handle shaft is reduced without lowering strength of these shafts, so that transmitting efficiency of rotating torque from a drive gear to a pinion gear can be heightened and a reel main body can be miniaturized. In the spinning reel for fishing, a part of the handle shaft crossing with the spool shaft is formed as a small diameter portion determined to have a smaller diameter than those of other parts of the handle shaft, and a part of the handle which is connected to the handle shaft is less to extend within the handle shaft to traverse the crossing portion of the spool shaft and the handle shaft.

  • Patent number: 6561448
    Abstract: The present invention comprises a convertible fishing reel which has a unique design to allow for a more efficient line casting and line retrieval. To accomplish this, a preferred embodiment of the invention comprises two separate components, a main-body chassis and a spool chassis. The spool chassis is connected to at least one support arm of the main-body chassis. The connection is such that the spool chassis can be rotated 90 degrees within the spool chassis, to be perpendicular to the main-body chassis in line casting position and parallel to the main-body chassis in a line retrieval position.
