A support plate and a reel side plate are mounted on the outside of the left side frame, while a reel side plate is mounted on the outside of the right side frame. A spool is interposed between the left and right side frames and is fixed to a spool shaft. The spool is structured such that it can be rotated by a handle. A handle shaft is disposed in the rear of the spool shaft on the opposite side to a fishline play-out direction. Between the left and right side frames, a level wind device is disposed in front of the spool on the fishline play-out direction side.

    Abstract: A bait cast reel of the type having a line-carrying spool, a rotatable crank handle with an associated crank shaft for imparting rotation to the spool to wind line thereon, a line guide, and a worm gear operable in response to rotation of the crank shaft for causing reciprocative movement of the line guide across the spool as the spool is rotated to thereby evenly distribute line on the spool, wherein the structure of the guide track (guide) for the line guide, and, in particular, the cross-sectional shape of the guide, matches the cross-sectional shape of an opening in the frame of the reel such that during assembly the guide may be aligned with and inserted through the matching opening. Thereafter, the guide is rotated so that a portion is out of alignment with the opening and an attaching member is passed through the frame and through the out of alignment portion of the guide. The guide is positioned to support the line guide as the line guide is reciprocated to evenly lay the line on the spool.

  • Patent number: 5308019
    Abstract: A level-wind mechanism in a fishing reel of the multiplier type is, as a one-piece unit, removable from and insertable in the fishing reel frame which has two side members. This unit consists of a sleeve having a longitudinal slot, an endless screw rotatably mounted in the sleeve, a level-wind mounted on the sleeve and having a groove-follower pin which via the slot in the sleeve meshes with the endless screw in order, during rotation thereof, to move the level-wind back and forth along the sleeve, and a member for preventing the level-wind from being rotated on the sleeve. The frame has a recess in each side member. The unit is inserted in these recesses such that its sleeve extends parallel to the line-spool shaft while resting on the bottom of the recesses. The unit is retained in the recesses by means of projections on two side covers mounted on a respective side member. A radial projection is provided for preventing the sleeve from being rotated in the recesses.

    Abstract: A fishing reel is formed of a spool for winding up a fishing line, a traverse shaft provided with a spiral guide portion and rotatable in response to rotation of the spool, an enclosure for enclosing at least one side portion of the traverse shaft, and a level winder. The traverse shaft extends through the level winder by a first bore, and the enclosure extends through the level winder by a second bore. The level winder includes a guided member engageable with the spiral guide portion of the traverse shaft which is attached through a third bore perpendicularly connected to the first bore. The level winder is slidably reciprocated due to guiding engagement between the guided member and the spiral guide portion based on rotation of the traverse shaft to thereby wind up the fishing line in the spool. The portions of the level winder defining the first bore, the second bore and the third bore, respectively, are formed integrally with each other.
