The lid portion has a cover portion and a mounting leg portion. The cover portion is mounted detachably to the casing to cover the opening of the casing. The cover portion is formed unitarily with a second flange portion so as to define a space in the interior thereof. The mounting leg portion extends from the cover portion and to the front end of which a fishing rod can be mounted. In this reel unit, the weight of the lid portion is reduced at low cost while precision and relative strength are maintained.

Abstract: A spinning reel rotor includes a cylindrical portion, first and second rotor arms, a bail arm, and a second cover member. The cylindrical portion is mounted rotatably to one end of a reel unit. The first and a second rotor arms extend in a direction away from the reel unit while being curved outward in radial direction from a position in opposition, with respect to the radial direction, to an end of the cylindrical portion on the reel unit side. An aperture is formed in the second rotor arm. The second cover member covers the outside of the second rotor arm and has through holes for adjusting its mass. The through holes expose a portion of the aperture. In this rotor that has a rotor arm provided with an aperture, variations in the rotational balance of cover members due to different degrees of exposure of the aperture are suppressed.

Abstract: A seat member of a reel unit of a spinning reel is fixed by means of a screw member to a cover portion of a lid member formed by die casting in a direction in which a body member and the lid member are separated from each other. The lid member is mounted to the body member to which various mechanisms have been mounted, and a cover member is mounted to the lower rear portion of the reel unit. Then, the cover member and the body member are fixedly coupled to each other by means of a screw member in a direction transverse to the direction in which the body member and the lid member are separated from each other, i.e., a direction transverse to the direction in which the body member and the lid member are extracted from the die.

Abstract: An oscillating mechanism is for reciprocating a spool in a spool shaft direction in cooperation with rotation of a handle. The oscillating mechanism includes a slider member, a gear member, and a guide shaft. The slider member is mounted at least axially immovably to a spool shaft, on the fore end of which the spool is mounted. The gear member reciprocates the slider member in the shaft axial direction in cooperation with rotation of the handle. The guide shaft is supported at two locations of its outer circumferential surface with the reel unit, has an annular groove to which a retainer can be attached for preventing disengagement of the guide shaft in one axial direction, and guides the slider member in a direction substantially parallel to the spool shaft. In this way, structure for retaining a guide shaft is simplified and design constraint alleviated.

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.

Abstract: First sounding mechanism, which issues sound when spool rotates relative to spool shaft, is furnished with sound-emitting member, pawl member, and plate spring. Sound-emitting member is non-rotatably mounted on spool shaft, and has multiple jags radially jutting on its outer periphery. Pawl member has body portion pivotably mounted on spool; pawl portion formed on the spool-shaft side of the swing center; and arcuate contact face formed on body portion on a side of the swing center SC opposite spool shaft. First-side radius R1 of contact face, is smaller than its second-side radius R2. Plate spring mounted on spool at an end nearer the first side of contact-face is, and contacts contact face at the other end, urging pawl portion of pawl member to collide with sound-emitting member. In a spinning-reel sounding device having a pawl member, the tone fluctuations due to spool rotational direction are controlled.
