Spinning reel for fishing

In a spinning reel for fishing, a plurality of line guide portions are formed in a line roller, so that one of the fishing line guide portions can be selected and used by changing the mounting position or mounting direction of the line roller with respect to a support member. The spinning reel for fishing with such line roller is able to cope with or use a wide variety of fishing lines having different diameters.

BACKGROUND OF THE INVENTION 
The present invention relates to a spinning reel for fishing. 
Conventionally, as known well, in a spinning reel for fishing, a 
semicircular-shaped bail is mounted on the leading ends of a pair of 
support arms provided in a rotor through a pair of support members in such 
a manner that it can be freely reversed between a fishing line take-up 
position side and a fishing line play-out position side, and a line roller 
for guiding a fishing line from the tip end of a fishing rod toward a 
spool is mounted on one of the two support members. 
And, if the bail is reversed to the fishing line take-up position and the 
rotor is rotated in the fishing line take-up direction by operating a 
handle, then the fishing line is wound through the line roller around the 
spool which, in linking with the rotation of the rotor, traverses in the 
longitudinal direction thereof. On the other hand, if the bail is reversed 
to the fishing line play-out position side and the terminal tackles of the 
fishing rod is thrown, then the fishing line wound around the spool can be 
played out in a spiral manner. 
That is, conventionally, in the spinning reel for fishing of this type, 
there is employed such structure that, when the fishing line is taken up, 
the line roller is rotated around the spool to thereby guide the fishing 
line from the tip end of the fishing rod toward the spool. However, with 
use of this structure, not only the rotation of the rotor causes the 
fishing line (outer line) to be twisted, but also the path of the fishing 
line cannot be stabilized due to variations in the position of the line 
roller with respect to a fishing rod guide, due to variations in the 
winding diameter of the fishing line to be wound around the spool, due to 
variations in the position of the longitudinally traversing spool, and the 
like, so that the fishing line can be slid in the axial direction of the 
line roller on the outer peripheral surface of the line roller as the 
fishing line is taken up onto the spool, which is known a great factor in 
causing the fishing line to be twisted. 
In view of the above, in recent years, as disclosed in Japanese Utility 
Model Publication No. 6-46467 of Heisei, Japanese Registered Utility Model 
Publication No. 3020798, and Japanese Patent Publication No. 8-308444 of 
Heisei, there has been proposed a structure of a type that a guide groove 
is formed on the outer peripheral surface of the line roller, or, in the 
line roller, there is provided a guide portion with which the fishing line 
can be contacted in the fishing line take-up operation to thereby restrict 
the movement of the fishing line on the outer peripheral surface of the 
line roller in the axial direction thereof so as to prevent the fishing 
line from being twisted unnecessarily. 
Also, in Japanese Patent Publication No. 8-23834 of Heisei, there is 
disclosed a spinning reel for fishing structured such that a restricting 
portion for restricting the movement of the fishing line in the fishing 
line take-up operation is provided in the peripheral edge portion of the 
line roller and also the outer peripheral surface of the line roller is 
formed in a tapered surface. According to this spinning reel for fishing, 
not only the restricting portion restricts the movement of the fishing 
line on the outer peripheral surface of the line roller in the axial 
direction thereof to thereby be able to prevent the fishing line from 
being twisted on the line roller, but also the tapered shape of the outer 
peripheral surface of the line roller is used to give the fishing line the 
reversed rotation to the rotor rotation to thereby be able to reduce 
greatly the twisting of the outer part of the fishing line caused by the 
rotor rotation. 
However, in actual fishing, the fishing line to be wound around the spool 
must be selected according to the kind and size of the fish to be angled, 
fishing methods and the like; that is, out of many kinds of fishing lines, 
a fishing line having a proper diameter is selected and used. 
Therefore, in the conventional spinning reel for fishing structured such 
that a single guide groove is formed on the outer peripheral surface of 
the line roller to thereby restrict the movement of the fishing line in 
the axial direction of the line roller, only the fishing line having a 
diameter corresponding to the groove width of the guide groove can be 
used. That is, this conventional spinning reel for fishing is restricted 
by the fishing line used so that it is not able to use a wide variety of 
fishing lines due to the restrictions relating to the diameters of the 
fishing lines. 
Also, in the conventional spinning reel for fishing structured such that 
the outer peripheral surface of the line roller is formed in a tapered 
surface as well, since the preferred taper angle of the tapered surface 
varies according to the diameters of the fishing lines. In other words, in 
the conventional spinning reels for fishing, in order to be able to cope 
with a wide variety of fishing line diameters, it is inconveniently 
necessary to prepare a plurality of spinning reels respectively mounting 
therein line rollers in which the groove widths of the guide grooves are 
different according to the diameters of the fishing lines used, or in 
which the taper angles of the tapered surfaces are different according to 
the diameters of the fishing line used. 
Further, when the guide groove of the line roller is worn due to use for a 
long period of time, the present line roller must be replaced with a new 
line roller; that is, such line roller replacement requires another 
operation, which results in the inefficient operation of the spinning 
reel. 
SUMMARY OF THE INVENTION 
The present invention aims at eliminating the drawbacks found in the 
above-mentioned conventional spinning reels for fishing. Accordingly, it 
is a first object of the invention to provide a spinning reel for fishing 
which is not restricted by fishing lines used but is able to use a wide 
variety of fishing lines having different line diameters and also, even 
when a line roller is worn due to use for a long period of time, can 
relieve an operation to replace the worn line roller with a new line 
roller. 
And, it is a second object of the invention to provide a spinning reel for 
fishing which not only prevents a fishing line from being twisted 
unnecessarily when the fishing line is taken up, but also is able to use a 
wide variety of fishing line having different line diameters. 
In attaining the above objects, the invention provides the following 
spinning reel for fishing. 
(1) A spinning reel for fishing which comprises: a rotor rotatably mounted 
on a reel main body; a spool which is supported by the reel main body 
through a spool shaft and around which a fishing line can be wound when 
the rotor is rotated by operating a hand-operated handle; and a line 
roller which is mounted on the rotor through a support member and also 
which, when a fishing line is taken up, guides the fishing line from the 
tip end portion of a fishing rod toward the spool. There are provided a 
plurality of fishing line guide portions in the line roller, and one of 
the plurality of fishing line guide portions can be selected and used by 
changing the mounting position or direction of the line roller with 
respect to the support member. 
(2) In the spinning reel for fishing as set forth in (1), the plurality of 
fishing line guide portions are respectively made up of restricting 
portions provided on the peripheral edge portions of the line roller for 
restricting the movement of a fishing line when the fishing line is taken 
up, and tapered surfaces decreasing in diameter sequentially from the 
central portion of the line roller toward the restricting portions, and 
the tapered surfaces of the plurality of fishing line guide portions are 
different in the taper angles thereof from one another. 
(3) In the spinning reel for fishing as set forth in (1), the plurality of 
fishing line guide portions are respectively made up of guide grooves so 
formed in the outer peripheral surface of the line roller as to extend in 
the peripheral direction thereof and equal in groove width to one another, 
and the guide grooves are arranged in parallel to one another in the axial 
direction of the line roller. 
(4) In the spinning reel for fishing as set forth in (1), the plurality of 
fishing line guide portions are respectively made up of guide grooves so 
formed in the outer peripheral surface of the line roller as to extend in 
the peripheral direction thereof and different in groove width from one 
another, and the guide grooves are arranged in parallel to one another in 
the axial direction of the line roller. 
(Operation) 
According to the spinning reel for fishing as set forth in (1), if the 
plurality of fishing line guide portions are so formed as to be identical 
in structure with one another, when one of the fishing line guide portions 
is worn, another fishing line guide portion can be used by changing the 
mounting position or direction of the line roller. 
Also, if the plurality of fishing line guide portions are formed to be 
different in structure from one another to thereby be able to cope with 
different fishing line diameters, then the fishing line guide portions 
that correspond to the fishing line diameters can be used by changing the 
mounting position or mounting direction of the line roller. 
According to the spinning reel for fishing as set forth in (2), if any one 
of the fishing line guide portions is selected by changing the mounting 
position or mounting direction of the line roller according to the fishing 
line diameters, then not only the restricting portions can restrict the 
movement of the fishing line in the axial direction of the line roller to 
thereby prevent the fishing line from being twisted on the line roller, 
but also the tapered surface, in accordance with the fishing line 
diameters, can prevent the outer part of the fishing line from being 
twisted when the fishing line is taken up and causes the inner part of the 
fishing line to be twisted in the opposite direction to the twisting of 
the fishing line due to the rotation of the rotor. And, such twisting of 
the fishing line inner part will cancel out the twisting of the fishing 
line caused when the fishing line is played out, so that both of these 
twistings can be solved. 
Further, according to the spinning reel for fishing as set forth in (3), 
when any one of the guide grooves is worn because it is used for a long 
period of time, another one of the guide grooves can be used as a 
replacement by changing the mounting position or mounting direction of the 
line roller. 
And, in the take-up operation of the fishing line, the guide groove 
restricts the movement of the fishing line in the axial direction of the 
line roller to thereby prevent the fishing line from being twisted on the 
line roller. 
According to the spinning reel for fishing as set forth in (4), if one of 
the guide grooves is selected according to the fishing line diameters by 
changing the mounting position or mounting direction of the line roller, 
then the thus selected guide groove can restrict the movement of the 
fishing line in the axial direction of the line roller to thereby prevent 
the fishing line from being twisted on the line roller.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
Now, description will be given below in detail of the embodiments of a 
spinning reel for fishing according to the invention with reference to the 
accompanying drawings. 
In particular, FIGS. 1 to 4 show an embodiment of a spinning reel for 
fishing according to the invention. In FIG. 1, reference character 1 
designates a rotor which is rotatably mounted on a reel main body 3, while 
a pair of bail support arms 5 are formed integrally with the rotor 1. 
And, as shown in FIG. 2, a semiannularly-shaped bail 7 is mounted on the 
leading ends of the two bail support arms 5 through a bail arm 11 with a 
line roller 9 mounted thereon and a bail holder 13 in such a manner that 
the bail 7 can be freely reversed between a fishing line take-up position 
side and a fishing line play-out position side. 
Also, reference character 15 designates a spool which is coaxially arranged 
with respect to the rotor 1. This spool 15 is supported on a spool shaft 
(not shown) which can be traversably mounted on the reel main body 3, and, 
similarly to the conventional spinning reel for fishing, if the bail 7 is 
reversed to the fishing line take-up position side and the rotor 1 is 
rotated in a fishing line take-up rotation direction by means of operation 
of a handle 17, then a fishing line 19 can be wound around the spool 15 
which traverses in the longitudinal direction thereof in linking with the 
fishing line take-up rotation of the rotor 1. 
In a spinning reel 21 according to the present embodiment, in addition to 
the above-mentioned structure which is similar to the conventional 
spinning reel, a plurality of fishing line guide portions are formed in 
the line roller 9, while one of the fishing line guide portions can be 
selected and used by changing the mounting direction of the line roller 9 
with respect to the bail arm 11. 
Now, describing the characteristic features of this structure in detail, 
FIG. 3 shows a section view of a mounting structure for the line roller 9, 
in which reference character 23 designates a line slider. The line slider 
23 is fixed to the bail arm 11 by a bolt 26 through a support shaft 25 
which is formed of metal and is fitted with the line slider 23. A 
cylindrical member 27 formed of metal is placed on the bail arm 11 side 
end portion of the support shaft 25 and, in particular, by fastening the 
support shaft 25 to the bail arm 11 by the bolt 26, the present 
cylindrical member 27 is held by and between the support shaft 25 and bail 
arm 11. 
And, the inner race 29a of a ball bearing 29 is contacted with the end 
portion of the cylindrical member 27 to thereby mount the ball bearing 29 
on the outer periphery of the support shaft 25, while the line roller 9 is 
rotatably mounted on the support shaft 25 through the ball bearing 29. If 
the bolt fastening between the support shaft 25 and bail arm 11 is 
removed, then not only the line roller 9 can be removed easily but also 
the line roller 9 can be supported on the support shaft 25 in such a 
manner that it can be rotated while changing the right and left directions 
thereof. 
On the right and left peripheral edge portions of the line roller 9, as 
shown in FIG. 3, there are formed integrally therewith annular-shaped 
restricting portions 31 and 33 with their respective leading ends 
projecting toward the central portion of the line roller 9; and, in the 
central portion of the outer peripheral surface of the line roller 9, 
there is formed a disk-shaped partition wall 35 which projects outwardly 
and extends along the peripheral (circumferential) direction of the line 
roller 9. 
And, on the outer peripheral surface of the line roller 9, there are formed 
tapered surfaces 37 and 39 which respectively decrease in diameter 
sequentially from the partition wall 35 toward the two restricting 
portions 31 and 33 and are different in the taper angles thereof from each 
other. In particular, the tapered surface 37 having a larger taper angle 
and the restricting portion 31 function as a fishing line guide portion 
for guiding a large-diameter fishing line; and, if the line roller 9 is 
removed from the bail arm 11 and, as shown by a two-dot chained line in 
FIG. 4, the right and left mounting directions of the line roller 9 are 
changed over to each other, then the tapered surface 39 having a smaller 
taper angle and the restricting portion 33 function as a fishing line 
guide portion for guiding a small-diameter fishing line. 
Also, as shown in FIG. 3, in the bail arm 11 and line slider 23, 
respectively, there are disposed annular-shaped guide portions 41 and 43 
which project in the axial direction of the line roller 9 and are used to 
cover their respective restricting portions 31 and 33, while the guide 
portion 43 disposed on the line slider 23 side is extended up to the 
partition wall 35. 
In addition, in FIG. 3, reference character 45 designates a washer which is 
formed of fluorine-system resin (such as Teflon (a registered trademark) 
or the like) and is mounted between the line roller 9 and cylindrical 
member 27. 
Generally, as the material of a line roller, there are often used various 
kinds of hard materials such as ceramics and those which can be obtained 
by performing a hard plating treatment on the ceramics or copper alloy; 
and, the above-mentioned line roller 9 is also formed of one of such hard 
materials. 
Also, the taper angles of the tapered surfaces 37 and 39 may be set in the 
range of 1.degree.-10.degree.. However, these taper angles are to be set 
properly according to the size of a spinning reel in its design stage and, 
therefore, the taper angles are not limited to the above-mentioned range 
at all. 
As the present embodiment is structured in the above-mentioned manner, 
after the line roller 9 is mounted onto the bail arm 11 in such a mounting 
direction as shown in FIG. 3, if the bail is reversed to the fishing line 
take-up position side and the rotor 1 is rotated in the fishing line 
take-up rotation direction (in FIG. 3, in a direction of an arrow A) by 
operating the handle 17, then the fishing line 19 is wound around the 
spool 15 that traverses in the longitudinal direction in linking with the 
rotation of the rotor 1. Since the tapered surface 37 is formed in such a 
tapered manner that it increases sequentially toward the fishing line 
take-up rotation direction, in association with the fishing line take-up 
operation the fishing line 19 is given a force which causes itself to be 
rotated in a direction of an arrow B, that is, a force which causes the 
fishing line 19 to be rotated along the tapered surface 37, so that the 
fishing line 19 is caused to be twisted in the opposite direction to the 
direction in which it is twisted due to the rotor rotation, thereby 
preventing the outer part of the fishing line from being twisted; and, at 
the same time, in the fishing line (in particular, the inner part of the 
fishing line) to be wound on the spool 15, there is produced a twisting in 
the opposite direction to the twisting caused by the rotor rotation, and 
this twisting can be canceled out or removed by a twisting which is caused 
when the fishing line is played out. 
And, the fishing line 19, which has been given the force that causes the 
fishing line 19 to rotate in the arrow B direction and thereby rotate 
along the tapered surface 37 through the fishing line take-up operation, 
is always contacted with the restricting portion 31 and is thereby 
restricted in the movement thereof in the axial direction of the line 
roller 9. That is, such restriction of the movement of the fishing line 19 
on the outer peripheral surface of the line roller 9 in the axial 
direction of the line roller 9 can prevent the fishing line 19 from being 
twisted on the line roller 9. 
Also, when a fishing line having a smaller diameter than the fishing line 
19 is used according to the kind, size or the like of the fish to be 
angled, as described before, the bolt 26 may be removed and the line 
roller 9 may be thereby removed from the bail arm 11; and, as shown by the 
two-dot chained line in FIG. 4, the right and left mounting directions of 
the line roller 9 may be changed over to each other and thus the tapered 
surface 39 having a smaller taper angle and restricting portion 33 may be 
used as the fishing line guide portion. 
In this case as well, if the rotor 1 is rotated in the fishing line take-up 
rotation direction by means of operation of the handle 17, then the 
fishing line is wound around the spool 15 that traverses back and forth in 
linking with the rotation of the rotor 1. However, since the tapered 
surface 39 is formed in such a tapered manner that it increases in 
diameter sequentially toward the fishing line take-up rotation direction, 
in association with the fishing line take-up operation the fishing line is 
given a force which causes the fishing line to be rotated along the 
tapered surface 39, so that the fishing line is twisted in the opposite 
direction to a twisting which is produced in the fishing line due to the 
rotor rotation, thereby preventing the outer part of the fishing line from 
being twisted; and, at the same time, in (the inner part of) the fishing 
line wound on the spool 15, there is produced a twisting in the opposite 
direction to the twisting due to the rotor rotation. 
And, the fishing line, which has been given the force that causes the 
fishing line 19 to rotate along the tapered surface 37 through the fishing 
line take-up operation, is contacted with the restricting portion 33 and 
is thereby restricted in the movement thereof in the axial direction of 
the line roller 9. That is, such restriction of the movement of the 
fishing line on the outer peripheral surface of the line roller 9 in the 
axial direction of the line roller 9 can prevent the fishing line from 
being twisted on the line roller 9. 
As described above, in the present embodiment, the two tapered surfaces 37 
and 39 having different taper angles are formed on the outer peripheral 
surface of the single line roller 9, and, in the right and left peripheral 
edge of the line roller 9, respectively, there are formed the 
annularly-shaped restricting portions 31 and 33 with their respective 
leading ends projecting toward the central portion of the line roller 9, 
whereby, by changing the right and left mounting directions of the line 
roller 9 with respect to the bail arm 11, the tapered surface 37 and 
restricting portion 31 can function as the fishing line guide portion for 
a large-diameter fishing line, and the tapered surface 39 and restricting 
portion 33 can function as the fishing line guide portion for a 
small-diameter fishing line. Due to this, even when fishing lines having 
different diameters are used, execution of a simple operation to change 
the right and left mounting directions of the line roller 9 makes it 
possible to prevent production of an unnecessary twisting in the fishing 
line when the fishing line is taken up; and, at the same time, there is 
eliminated a troublesome problem that a plurality of spinning reels 
respectively mounting thereon line rollers differing in taper angle 
according to the diameters of the fishing lines used must be prepared. 
That is, the present embodiment is able to use a wide variety of fishing 
lines which are different in diameters. 
Now, FIG. 5 shows an embodiment of a mounting structure for mounting a line 
roller to be mounted on a spinning reel for fishing according to the 
invention, and description will be given below of the present embodiment 
with reference to FIG. 5. The other portions of the present embodiment 
than the inventive portion thereof are similar in structure to those 
employed in the previously described embodiment. Therefore, the following 
description will be given of only the inventive portion of the present 
embodiment, while the same components are given the same designations and 
thus the description thereof is omitted here. 
In FIG. 5, reference character 47 designates a line roller which, similarly 
to the previously described line roller 9, is rotatably mounted on the 
support shaft 25 through the ball bearing 29. By removing the bolt 
fastening between the support shaft 25 and bail arm 11, not only the line 
roller 47 can be removed easily but also the line roller 47 can be 
supported on the support shaft 25 in such a manner that it can be rotated 
while changing the right and left mounting directions thereof as the need 
arises. 
And, the line roller 47, which is so formed as to have a cylindrical outer 
shape, includes on the outer peripheral surface thereof two guide grooves 
49 and 51 which extend in the peripheral direction of the line roller 47 
and are equal in groove width to each other; and, in particular, the two 
guide grooves 49 and 51 are arranged in parallel to each other in the 
axial direction of the line roller 47 with the same distance from the 
right and left end sides of the line roller 47. If the line roller 47 is 
mounted on the bail arm 11 in such a state as shown in FIG. 5, then one 
guide groove 51 is to be covered with the guide portion 43 of the line 
slider 23. 
Since the present embodiment is structured in this manner, if the line 
roller 47 is mounted onto the bail arm 11 in such a direction as shown in 
FIG. 5, the bail 7 is reversed to the fishing line take-up position side, 
and the rotor 1 is rotated in the fishing line take-up rotation direction 
(in FIG. 5, in a direction of an arrow A) by means of operation of the 
handle, then the fishing line 19 is wound around the spool 15 which 
traverses back and forth in linking with the rotation of the rotor 1. In 
this case, the fishing line 19 is always guided into the guide groove 49 
and thus the movement of the fishing line 19 in the axial direction of the 
line roller 47 can be restricted, which in turn can prevent the fishing 
line 19 from being twisted on the line roller 47. 
Also, when the opening edge portion or the like of the guide groove 49 is 
worn due to use for a long period of time, the bolt 26 may be removed, the 
line roller 47 may be then removed from the bail arm 11, and the guide 
groove 51 may be situated on the bail arm 11 side by changing the right 
and left mounting directions of the line roller 47 over to each other. 
Accordingly, in this case as well, in the fishing line take-up operation, 
the guide groove 51 can restrict the movement of the fishing line 19 in 
the axial direction of the line roller 47 to thereby be able to prevent 
the fishing line 19 from being twisted on the line roller 47. 
As described above, according to the present embodiment, not only the 
occurrence of the unnecessary twisting in the fishing line in the take-up 
operation of the fishing line can be prevented, but also, when any one of 
the guide grooves 49 and 51 formed in the line roller 47 is worn due to 
use for a long period of time, the other of the guide grooves 49 and 51 
can be used by changing the right and left mounting positions of the line 
roller 47 over to each other. Thanks to this, when compared with the 
conventional structures, an operation to replace the old worn line roller 
with a new one is reduced by half, that is, the present embodiment is more 
efficient than the conventional structures in the after-operation such as 
the replacement of the line rollers and the like. 
Now, FIG. 6 shows an embodiment of a mounting structure for mounting a line 
roller to be mounted on a spinning reel for fishing according to the 
invention. 
In the present embodiment as well, the same components thereof as those 
employed in the previously described embodiment shown in FIG. 1 are given 
the same designations. 
In FIG. 6, reference character 53 designates a line roller mounted on the 
bail arm 11 through the ball bearing 29. Similarly to the previously 
described respective embodiments of the invention, not only the line 
roller 53 can be removed easily by removing the bolt fastening between the 
support shaft 25 and bail arm 11, but also the line roller 53 can be 
supported on the support shaft 25 in such a manner that it can be rotated 
while changing the right and left mounting directions thereof as the need 
arises. 
And, the line roller 53, which is so formed as to have a cylindrical outer 
shape, includes on the outer peripheral surface thereof two guide grooves 
55 and 57 which extend in the peripheral direction of the line roller 53 
and are different in groove width from each other; and, in particular, the 
two guide grooves 55 and 57 are arranged in parallel to each other in the 
axial direction of the line roller 53 while they are equidistant from the 
right and left end sides of the line roller 53. If the line roller 53 is 
mounted on the bail arm 11 in such a state as shown in FIG. 6, then the 
guide groove 51 having a larger groove width is to be covered with the 
guide portion 43 of the line slider 23 and, on the other hand, if the 
right and left mounting directions of the line roller 53 are changed over 
to each other, then the guide groove 55 having a smaller groove width is 
to be covered with the guide portion 43. 
Since the present embodiment is structured in this manner, if the line 
roller 53 is mounted onto the bail arm 11 in such a direction as shown in 
FIG. 6, the bail 7 is reversed to the fishing line take-up position side, 
and the rotor 1 is rotated in the fishing line take-up rotation direction 
(in FIG. 6, in a direction of an arrow A) by means of operation of the 
handle, then the fishing line 19 is wound around the spool 15 which 
traverses back and forth in linking with the rotor rotational movement. In 
this case, the fishing line 19 is always guided into the guide groove 55 
and thus the movement of the fishing line 19 in the axial direction of the 
line roller 53 can be restricted, which in turn can prevent the fishing 
line 19 from being twisted on the line roller 53. 
Also, when using a fishing line having a larger diameter than the 
illustrated fishing line 19 according to the kind, size or the like of the 
fish to be angled, the line roller 53 may be removed from the bail arm 11, 
the right and left mounting directions of the line roller 53 may be 
changed over to each other, and the guide groove 57 having a larger groove 
width may be used as a fishing line guide portion. 
Accordingly, in this case as well, in the fishing line take-up operation, 
the guide groove 57 is sure to restrict the movement of the heavy fishing 
line 19 in the axial direction of the line roller 53 to thereby be able to 
prevent the heavy fishing line 19 from being twisted on the line roller 
53. 
As described above, according to the present embodiment as well, it is 
possible to prevent the occurrence of the unnecessary twisting in the 
fishing line 19 in the take-up operation of the fishing line 19. 
And, by changing the right and left mounting directions of the line roller 
53 with respect to the bail arm 11, the guide groove 55 can be used as a 
fishing line guide portion for a fine fishing line, while the guide groove 
57 having a larger groove width than the guide groove 55 can be used as a 
fishing line guide portion for a heavy fishing line. Thanks to this, even 
when fishing lines having different diameters are used, such fishing lines 
can be properly dealt with according to the diameters of the fishing lines 
by a simple operation to change the right and left mounting directions of 
the line roller 53 over to each other. That is, according to the present 
embodiment, it is possible to solve a troublesome problem that a plurality 
of spinning reels respectively mounting thereon line rollers including 
guide grooves different in groove width must be prepared. 
Now, FIG. 7 shows a mounting structure for mounting a line roller to be 
mounted on a spinning reel for fishing according to an embodiment of the 
invention. 
In FIG. 7, reference character 59 designates a line roller which is mounted 
on a support shaft 25-1 through a ball bearing 29-1. And, the line roller 
59, which is so formed as to have a cylindrical outer shape, includes on 
the outer peripheral surface thereof three guide grooves 61, 63 and 65 
which are arranged in parallel to one another in the axial direction of 
the line roller 59, while these three guide grooves 61, 63 and 65 increase 
sequentially in groove width in this order. 
As described above, the line roller 59 is mounted on the support shaft 25-1 
through the ball bearing 29-1; and, in particular, the inner race 29a-1 of 
the ball bearing 29-1 is engaged with an engaging recessed portion 69 of a 
mounting member 67 which is mounted on the outer periphery of the support 
shaft 25-1, while the outer race 29a-2 of the ball bearing 29-1 is engaged 
with an engaging recessed portion 71 formed in the inner periphery of the 
line roller 59. 
And, in the outer periphery of the support shaft 25-1, there are formed 
three securing holes 77, 79 and 81 which are arranged in the axial 
direction of the line roller 59 and to which a securing pin 75 can be 
secured, while the securing pin 75 is arranged such that it can be 
inserted through a pin insertion hole 73 formed in the mounting member 67. 
For example, as shown in FIG. 7, if the securing pin 75 is secured to the 
securing hole 79, then the guide groove 63 is situated between two guide 
portions 41-1 and 43. 
Also, after the bolt fastening between the support shaft 25-1 and bail arm 
11-1 is removed, if the mounting member 67 is slid in an arrow direction 
to thereby secure the securing pin 75 to the securing hole 77, then the 
guide groove 65 is situated between the guide portions 41-1 and 43; and, 
if the mounting member is slid in the arrow direction to thereby secure 
the securing pin 75 to the securing hole 81, then the guide groove 61 is 
situated between the guide portions 41-1 and 43. 
By the way, the guide portion 41-1, when compared with the previously 
described guide portion 41, is extended further in the direction of the 
guide portion 43 on the line slider 23 side, while any one of the three 
guide grooves 61, 63 and 65 is to be situated between the two guide 
portions 41-1 and 43. 
Since the present embodiment is structured in this manner, after the line 
roller 59 is fixed at such a position as shown in FIG. 7, if the bail 7 is 
reversed to the fishing line take-up position side and the rotor 1 is 
rotated in the fishing line take-up rotation direction by operating a 
handle, then the fishing line 19 is wound around the spool 15 which 
traverses back and forth in linking with the rotation of the rotor 1 but, 
since the movement of the fishing line 19 in the axial direction of the 
line roller 59 is restricted by the guide groove 63, the fishing line 19 
is prevented from being twisted on the line roller 59. 
Also, when using a fishing line having a larger diameter than the 
above-mentioned fishing line 19 according to the kind, size or the like of 
the fish to be angled, if the line roller 59 is slid together with the 
mounting member 67 in the arrow direction to thereby secure the securing 
pin 75 to the securing hole 77, then the guide groove 65 having a larger 
guide groove than the guide groove 63 is situated between the guide 
portions 41-1 and 43; and, on the other hand, when using a fishing line 
having a smaller diameter than the above-mentioned fishing line 19, if the 
line roller 59 is slid in the arrow direction to thereby secure the 
securing pin 75 to the securing hole 81, then the guide groove 61 having 
the smallest guide width is situated between the guide portions 41-1 and 
43. 
In these cases as well, the respective guide grooves 61 and 65 can restrict 
the movement of the fishing line 19 in the axial direction of the line 
roller 59 in the fishing line take-up operation, thereby being able to 
prevent the fishing line 19 from being twisted on the line roller 59. 
Therefore, according to the present embodiment as well, not only it is 
possible to prevent the fishing line 19 from being twisted unnecessarily 
when the fishing line 19 is taken up, but also, if the line roller 59 is 
slid in the axial direction to thereby change its mounting position, then 
the spinning reel is able to cope with a wide variety of fishing lines 
having different diameters. This makes it possible to solve a troublesome 
problem that a plurality of spinning reels respectively mounting thereon 
line rollers including guide grooves different in groove width according 
to the different diameters of the fishing lines used must be prepared. 
By the way, the structures and combinations of the fishing line guide 
portions are not limited to the above-mentioned respective embodiments 
but, for example, it is also possible to enforce another embodiment in 
which fishing line guide portions each consisting of a tapered surface and 
a guide groove are provided on the outer peripheral surface of a single 
line roller. According to the present embodiment as well, similarly to the 
above-mentioned respective embodiments, an expected object can be 
achieved. 
Also, as in the above-mentioned respective embodiments, in the spinning 
reels of this type each of which mounts a bail, the bail arms are mounted 
on the bail support arm. Conventionally, however, there are present many 
spinning reels which do not mount a bail. 
And, in such conventional spinning reels, a support member corresponding to 
the above-mentioned bail arms is mounted on the rotor and a line roller is 
mounted on the support member. However, the present invention can also 
apply to the conventional spinning reels structured in this manner as 
well. 
As has been described heretofore, according to the spinning reel for 
fishing as set forth in (1), since a plurality of fishing line guide 
portions are provided in a single line roller, when these fishing line 
guide portions are so formed as to have the same structure, one of the 
fishing line guide portions can be selected and used by a simple operation 
to change the mounting position or mounting direction of the line roller, 
which can solve a troublesome problem, which arises in the prior art, that 
a plurality of spinning reels respectively mounting different kinds of 
line rollers must be prepared. 
And, when the above-mentioned plurality of fishing line guide portions are 
so formed as to have different structures, the present spinning reel is 
able to properly use a wide variety of fishing lines according to their 
diameters by a simple operation to change the mounting position or 
mounting direction of the line roller. 
Also, according to the spinning reel for fishing as set forth in (2) to 
(4), in addition to the above-mentioned effects, it is possible to prevent 
a fishing line from being twisted due to the different diameters thereof 
when the fishing line is taken up.
