[Problems to be solved by the invention]
In the conventional spinning reel, the mating portion on the side of the heel mounting leg exposed at the side of the main body member and the lid member is formed to be a straight line. For this reason, useless space may be produced | generated between the fitting part formed so that it might become a straight line, and the external shape of a main body member. Thus, when a useless space is generated in the main body member, it is possible to hinder downsizing of the entire reel and to reduce the strength of the reel main body.
[0006]
SUMMARY OF THE INVENTION An object of the present invention is to reduce the size of an entire reel and maintain the strength of the reel body high in the reel body of the spinning reel.
[0007]
[Means for Solving the Problems]
A reel body of a spinning reel according to a first aspect of the present invention is a spinning reel reel body that is mounted on a fishing rod and can feed a fishing line forward and winds the fishing line by rotating a handle. A leg body and a reel body provided continuously with the flange mounting leg section; The reel body includes a main body member having a storage space having a side portion opened therein, and a lid member that is detachably attached to the main body member so as to cover the opening of the main body member. The reel body is formed so that the mating portion on the side of the flange mounting leg exposed at the side portions of the main body member and the lid member is curved. Also, in the storage space of the main body member, the master gear that rotates by the rotation of the handle and the uppermost position of the outer diameter at the rear of the master gear are positioned below the uppermost position of the outer diameter of the master gear. A driven gear that is rotated by the rotation of the master gear and a slider that moves back and forth by the rotation of the driven gear are arranged. The mating portion is formed in a convex shape in the direction opposite to the saddle mounting leg side and curved so as to incline from the side where the master gear is disposed toward the side where the driven gear is provided. ing.
[0008]
In this reel body, the reel body is formed so that the mating portion on the side of the heel mounting leg exposed on the side portions of the body member and the lid member is curved. Here, for example, by forming the mating portion so as to be curved along the outer shape of the main body member, a useless space can be saved between the mating portion of the main body member and the outer shape. Therefore, by eliminating such a useless space, the strength of the reel body can be maintained high while reducing the size of the entire reel.
[0009]
In addition, since the mating portion is formed to be curved in a convex shape in the direction opposite to the heel mounting leg side, that is, in the downward direction, there is relatively little wasted space between the mating portion and the outer shape of the main body member. Many can be omitted. In addition, the design can be improved by curving the mating portion downward so as to form a gentle curve in accordance with the outer shape of the reel .
[0010]
The reel unit of a spinning reel according to the inventions 2, the reel body of the invention 1, the rod attachment leg portion is integrally molded with the body member. In this case, since the heel mounting leg portion and the main body member are integrally formed, the configuration of the lid member is simplified as compared with the case where the heel mounting leg portion and the lid member are integrally formed.
[0011]
A reel main body of a spinning reel according to a third aspect of the present invention is the reel main body of the first aspect, wherein the collar mounting leg portion is integrally formed with the lid member. In this case, since the heel mounting leg and the lid member are integrally molded, the mixing of the thick part and the thin part is reduced, the main body member is made thin and the precision is maintained, and the mounting leg part is thick. Thus, the strength can be maintained.

The small diameter gear 20 is formed integrally with the large diameter gear 19 and rotates integrally with the large diameter gear 19.
[0031]
As shown in an enlarged view in FIG. 6, the large diameter gear 19 and the small diameter gear 20 are integrated with a large diameter gear shaft 18a formed to project inside the rear side wall of the main body member 2a and a tip of the large diameter gear shaft 18a. The small diameter gear shaft 18b is rotatably mounted. The diameter B of the small diameter gear shaft 18b is smaller than the diameter A of the large diameter gear shaft 18a. The axial length C of the large diameter gear shaft 18a is smaller than the axial length D of the small diameter gear shaft 18b. The large diameter gear 19 is attached to the entire large diameter gear shaft 18a and a part of the small diameter gear shaft 18b with a margin of length E. For this reason, since the small diameter gear 20 is attached to a portion excluding the length E of the small diameter gear shaft 18b, the bottom surface of the small diameter gear 20 can be lengthened outward in the axial direction by the length E. Therefore, since the root diameter of the small diameter gear 20 can be sufficiently secured, the strength of the small diameter gear 20 can be maintained high.
[0032]
A separate cam pin 16 a protruding toward the slider 22 is caulked and fixed to the side surface of the driven gear 16 as shown in an enlarged view in FIGS. 7 and 8. As shown in FIG. 7, the tip of the cam pin 16a is disposed so as to protrude outward from the root circle 16b, so that the sliding stroke can be increased while maintaining the gear diameter 16c.

[0033]
The slider 22 is supported by the main body member 2a so as to be movable back and forth. The slider 22 is connected to the rear end of the spool shaft 15 so as not to rotate but to move in the axial direction. A long cam groove 22a is formed on the side surface of the slider 22 facing the driven gear 16 in the vertical direction. A cam pin 16a is engaged with the cam groove 22a. The length of the cam groove 22a is slightly larger than the rotation diameter of the cam pin 16a.
[0034]
In the reduction gear type oscillating mechanism 6 having such a configuration, when the master gear shaft 10 rotates, the driven gear 16 rotates through the stepped gear 13 and the cam pin 16a rotates. When the cam pin 16a rotates, the slider 22 with the cam pin 16a engaged with the cam groove 22a moves back and forth to move the spool 4 back and forth.
[0035]
In the spinning reel having such a configuration, the mating portion S on the side of the flange mounting leg 36 exposed on the side portions of the main body member 2a and the lid member 2b is formed to be curved, so that the alignment of the main body member 2a is performed. A useless space can be saved between the part S and the reel outer shape. Therefore, by eliminating such a useless space, the strength of the reel body 2 can be maintained high while reducing the size of the entire reel.
[0036]
Here, since the mating portion S is formed to be a curve, the contact area between the main body member 2a and the lid member 2b is increased, and the durability under load can be improved. Further, when a force in the axial direction of the spool shaft 15 is applied to the reel body 2, the mating portion is formed to be a straight line substantially parallel to the spool shaft 15 in the conventional configuration. The cross-sectional area in the direction of the load changes rapidly at this portion, and this portion may break if the strength and thickness of the material of the reel body 2 are not sufficient. On the other hand, in the present embodiment, since the mating portion S is formed in a curve, the change in the cross-sectional area of the mating portion S can be moderated, and the strength of the reel body 2 can be maintained higher. .
