Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an improvement in a fishing spinning reel that rotates a rotor having a fishing line guide portion and winds a fishing line around a spool by rotating a handle connected to a winding drive mechanism of the reel body.
[Prior art]
In the reel body of the spinning reel for fishing, a winding drive mechanism for transmitting the rotational force from the handle to the rotor having the fishing line guide portion, and a spool reciprocating mechanism for converting the rotational force from the handle into the longitudinal movement of the spool And are decorated.
[0003]
Further, a handle shaft having a drive gear constituting the winding drive mechanism and a pinion to which the rotor is attached and fixed and the spool shaft is inserted are arranged in a state of being offset and orthogonal to each other (for example, Patent Document 1 and Patent Document 2).
[0004]
Further, in order to efficiently transmit the rotational force of the handle to the rotor smoothly during the high-load winding operation, the vicinity of the meshing portion of the rear end portion of the pinion that meshes with the drive gear on the handle shaft is supported by the reel body. It is rotatably supported by the part via a bearing (for example, refer patent document 2).
[0005]
Further, since the handle shaft having the drive gear is arranged away from the bearing portion of the reel body that supports the rear end portion of the pinion, including its bearing portion, the reel body that is the gear box is correspondingly large. Turn into. Therefore, a portion of the bearing portion of the reel body that supports the rear end portion of the pinion that is located on the handle shaft side is cut into an arcuate shape, and the handle shaft with respect to the bearing portion of the reel body that supports the rear end portion of the pinion is cut. In addition, it has been conventionally practiced to make the bearing portion close to each other and to easily process the bearing portion of the reel body that supports the handle shaft so that the bearing can be assembled without any trouble (for example, Patent Document 1).

[Problems to be solved by the invention]
However, if a part of the bearing portion of the reel body that supports the rear end portion of the pinion is cut and the handle shaft bearing portion and the bearing portion of the rear end portion of the reel body are brought close to each other, the rear end of the pinion When the part and the handle shaft are supported using a rolling bearing, there is a space limitation that the bearing space of the rear end portion of the pinion and the handle shaft is reduced. Therefore, it is difficult to reliably support the rear end portion of the pinion and the handle shaft with the rolling bearing while preventing the reel body from being enlarged.
[0009]
The present invention has been made paying attention to the above circumstances, and the object of the present invention is to fish that can reliably support the rear end of the pinion and the handle shaft with a rolling bearing while preventing the reel body from being enlarged. It is to provide a spinning reel for fishing.
[0010]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0012]
1 to 5 show an embodiment of the present invention. As shown in FIGS. 1 to 3, a fishing spinning reel 1 of the present embodiment is formed on a reel body 1a, a leg 1b extending from the reel body 1a, and an end of the leg 1b. It has the rod attachment part 1c attached to a fishing rod. A winding drive mechanism for winding a fishing line around a spool is provided in the reel body 1a. Specifically, the handle shaft 2 to which the handle 5 is fixed is rotatably supported in the reel body 1a. A drive gear 3 that is a drive gear is fixed to the handle shaft 2, and a pinion gear 13 is engaged with the drive gear 3.
[0013]
The pinion gear 13 is provided in a shaft cylinder 62 that extends in a direction orthogonal to the handle shaft 2 and is rotatably supported on the reel body 1a via bearings 60A and 60B. A rotor 8 having a bail 6 and a fishing line guide 15 is integrally attached to the tip of the shaft cylinder 62.
[0014]
A spool shaft 9 extending in a direction orthogonal to the handle shaft 2 passes through the shaft cylinder 62. In this case, the spool shaft 9 is arranged concentrically with the shaft cylinder 62 and can move back and forth along a direction orthogonal to the handle shaft 2. A spool 10 around which a fishing line is wound is attached to the tip of the spool shaft 9.
[0015]
The handle shaft 2 is formed with a gear 63 that meshes with the interlocking gear 66 of the oscillating mechanism (spool reciprocating mechanism) 65. When the handle shaft 2 is rotated by the rotation operation of the handle 5, the oscillating mechanism 65 reciprocates (backs and forth) the spool shaft 9 along the axial direction.
[0016]
In such a configuration, when the handle shaft 2 is rotated by rotating the handle 5, the spool 10 attached to the spool shaft 9 reciprocates back and forth via the oscillating mechanism 65, and the drive gear 3, the pinion The rotor 8 is rotationally driven via the gear 13 and the shaft cylinder 62. Accordingly, the fishing line is evenly wound around the spool 10 via the fishing line guide portion 15.
[0017]
As described above, the handle shaft 2 extends so as to intersect the spool shaft 9 in the reel body 1a. Specifically, as shown in FIGS. 2 and 3, both sides of the handle shaft 2 are rotatably supported by the reel body 1a via bearings 41 and 42, and the handle 5 is selectively fixed. The left and right end portions 2a, 2b of the handle shaft 2 are positioned in openings 50, 50 formed on the left and right sides of the reel body 1a so as to face both the left and right sides of the reel body 1a. A female screw 51 is formed in the openings 50, 50 of the reel body 1 a, and a lid 40 for closing the opening 50 is screwed into the female screw 51.
[0018]
Further, as clearly shown in FIG. 5, a bearing retaining cover 71 that prevents the bearings 41 and 42 from coming off from the reel body 1 a is attached and fixed to the reel body 1 a via pins 77. In this case, a washer 76 is interposed between the bearings 41 and 42 and the bearing retaining cover 71. That is, in this embodiment, as virtually shown in FIG. 5, the bearing retaining cover 71 is separated from the reel body 1a, and the bearings 41 and 42 are attached / detached (assembled) from the outside (outside) of the reel body 1a. It can be done.
[0019]
Further, as clearly shown in FIG. 4, the reel body 1 a is formed with a bearing portion 75 having a bearing 60 </ b> A that pivotally supports the rear end portion of the pinion 13. In this case, a part in the radial direction of the bearing 42 of the reel body 1a on the tooth surface side of the drive gear 3 that supports the handle shaft 2 is a predetermined amount X with respect to the bearing portion 75 that pivotally supports the rear end portion of the pinion 13. It arrange | positions so that it may superpose | polymerize (for example, in the axial direction of the pinion 13).
[0020]
Thus, in the present embodiment, as in the prior art, the portion of the bearing portion 75 of the reel body 1a that supports the rear end portion of the pinion 13 that is located on the handle shaft 2 side is bowed from the vertical base portion to the front end portion. Drive gear for supporting the handle shaft 2 instead of bringing the bearing portion (bearing 42) of the handle shaft 2 in the reel body 1a and the bearing portion 75 (bearing 60A) at the rear end portion of the pinion 13 close to each other. A configuration is adopted in which a part in the radial direction of the bearing 42 of the reel body 1a on the tooth surface side 3 is superposed on the bearing portion 75 that pivotally supports the rear end portion of the pinion 13 (for example, in the axial direction of the pinion 13). Thus, the bearing portion (bearing 42) of the handle shaft 2 in the reel body 1a and the bearing portion 75 (bearing 60A) at the rear end portion of the pinion 13 are separated by a predetermined amount (for example, in the axial direction of the handle shaft 2), The handle shaft 2 pivotally supported on the reel body 1a is secured to the pinion 13 in a state where a sufficient bearing space that can be supported by using the bearing is secured at the rear end of the pinion 13 (for example, in the axial direction of the handle shaft 2). The rear end portion can be disposed as close as possible to the bearing portion 75 that pivotally supports the rear end portion. Therefore, it is possible to maintain a good bearing function without increasing the size of the reel body 1a (the pinion 13 and the handle shaft 2 can be reliably secured by a rolling bearing without increasing the size of the reel body 1a. Can support).
[0021]
FIG. 6 shows a modification of the above-described embodiment. In this modification, for example, a groove-shaped escape portion 80 for releasing the gear 63 that meshes with the interlocking gear 66 of the oscillating mechanism 65 is formed in the bearing portion 75 of the reel body 1a. Since the other configuration is the same as that of the first embodiment, the same reference numerals are given and description thereof is omitted.
[0022]
In this way, when the escape portion 80 for escaping the gear 63 is formed in the bearing portion 75 of the reel body 1a, the handle shaft 2 can be brought closer to the pinion 13 side, so that the reel body 1a can be further downsized. Can be planned.
[0023]
FIG. 7 shows a reference example not included in the invention described in the claims . In this reference example , as shown by an arrow in the figure, a working escape portion 83 is formed at the base portion of the bearing portion 75 so that the bearing 42 can be incorporated from the inside of the reel body 1a. The working relief portion 83 is formed by a groove formed in the reel body 1a, and the end portion 82 of the groove can prevent the bearing 42 from coming off from the reel body 1a. Therefore, the bearing retaining cover 71 as in the above-described embodiment is not necessary. Since the other configuration is the same as that of the first embodiment, the same reference numerals are given and description thereof is omitted.
[0024]
