  • Patent number: 7374121
    Abstract: A fishing reel component includes a boss, a spring member, a lid member, a push button and spring arrangement member. The boss forms a boss through hole and a mounting space. The spring member is mounted in the mounting space. The spring member includes first and second engagement portions arranged to oppose each other. The lid member is fixed to the boss to retain the spring member and cover the mounting space. The push button includes a plurality of tapered portions. The tapered portions protrude from the push operation portion in the axial direction. The spring arrangement member arranges the spring member between the lid member and the spring arrangement member. The spring arrangement member includes a plurality of first through holes with each of the first through holes being configured for one of the tapered portions to pass therethrough.

  • Patent number: 7232086
    Abstract: An oscillation device axially oscillates a spool with handle rotation, and includes a driving gear, a cam gear, a slider, and a guiding portion. The driving gear is arranged on a master gear shaft, so as to be spaced apart from the master gear. The cam gear has a cam pin on its side surface, and is arranged on the fishing rod attachment side of the oscillation device relative to the master gear shaft. The cam gear is attached to the reel unit rotatably about an axis substantially parallel to the master gear shaft, so as to rotate in cooperation with the driving gear. The slider has a cam receiving portion engaging with the cam pin of the cam gear, and is axially immovably attached to the rear of the spool shaft. The guiding portion is provided in the reel unit and guides the slider movably in the axial direction.

  • Patent number: 7188794
    Abstract: An oscillating mechanism includes a first non-circular gear, a rotary cam and a slider. The first non-circular gear is a bi-lobe gear rotatable about an axis of the handle rotation. The rotary cam is rotatably mounted in the reel unit so as to be parallel with the first non-circular gear. The rotary cam includes a cam protrusion, and a multi-lobe second non-circular gear arranged so that a tooth corresponding to the minimum tip diameter of the second non-circular gear meshes with a tooth corresponding to the maximum tip diameter of the first non-circular gear. The number of teeth of the second non-circular gear is greater than that of the first non-circular gear. The slider is axially movably mounted to the spool shaft. The slider includes a cam groove engaging the cam protrusion. The present invention facilitates tight winding of fishing line in a shape closer to a cylindrical shape.

  • Patent number: 7118059
    Abstract: A spinning-reel reel unit includes a rod-attachment leg and a reel body having a main piece and a lid member. The lid member is integrally formed with the rod-attachment leg and is attachably/detachably fitted to the main piece. The main piece and the lid member are shaped so that a joint forms a curved seam on the rod-attachment leg side. The joint is formed so as to bulge downward on a side of the main piece away from the rod-attachment leg. The joint is formed so as to be tilted upward on the rod-attachment leg aside toward the front. In the spinning-reel reel unit, the overall size of the reel is reduced while the strength of the reel unit is kept high.

  • Patent number: 6712301
    Abstract: Sealing structure has a friction disk having a spindle-form boss portion, a cover member, and a seal member, in a lever-drag type dual-bearing reel. Cover member has a through-hole situated encompassing the boss portion, and is a component that is rotatable relative to friction disk. The seal member, which is a component made of an elastic substance, is for sealing a clearance between the boss portion and the cover member, and has an cylindrical portion made of an elastic substance and mountable on the boss portion, and a sealing portion formed integrally on the outer circumferential surface of the cylindrical portion and tapering toward the through-hole. A distal edge of the sealing portion is for contacting a contact surface in through-hole. The present invention provides a structure for sealing a spindle-form first member and, disposed about the outer periphery thereof, a second member, to seal while controlling impairment in rotational performance, without having to use components or space for fastening.

  • 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: 6464159
    Abstract: Paint-coated fishing component formed with recesses in which build-up of paint in the recesses is unlikely. A reel body (1) made of a magnesium alloy painted by electrodeposition includes a first side cover (6a) and a second side cover mounted to the sides of a frame. The first side cover (6a) is fastened by attaching screws (30) from the inner side of a first side plate (7a) to a plurality of protrusion portions (20) formed protruding on a rear surface. The protrusion portions (20) are provided with conduits (25) communicating recess portions formed with female threads to the immediate exterior. The conduits (25) are slits that are formed in the protrusion direction of the protrusions (20) or perpendicular to the protrusion direction, and are cut with a T-slot cutter, for example.
