Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drag mechanism, and more particularly to a drag mechanism for a dual-bearing reel capable of variably braking the rotation of a spool of the dual-bearing reel in the line payout direction by operating a star drag.

[0002]

2. Description of the Related Art A dual-bearing reel is provided with a drag mechanism for braking the rotation of a spool in a line payout direction.
The drag mechanism can adjust the drag force by operating the star drag. In general, a drag mechanism of a dual-bearing reel includes a plurality of disk members provided between a main gear and a star drag linked to a spool so as to be able to press against each other and to be able to press against the main gear. In the dual-bearing reel, a plurality of disk members are relatively moved in the axial direction of the handle shaft by operating a star drag screwed to the handle shaft, so that they are brought into pressure contact with each other to brake the spool via the main gear.

In a drag mechanism of this type of a dual-bearing reel,
At the time of drag operation, the disk member generates heat due to the friction of the disk member which is relatively rotated by the pulling of the fish. Therefore, it is preferable to use a material having wear resistance and heat resistance for at least one of the disk members. Conventionally, as a material having wear resistance and heat resistance, a phenolic resin laminated material, a cork material, a carbon fiber reinforced resin material, a metal material, and the like, which are formed by impregnating phenolic resin into paper or woven fabric and forming a laminate, have been used for disk members. ing. In a drag mechanism employing such a material, grease is applied to the entire surface of the disk member in order to prevent the braking force from becoming unstable (drag scratching) when moisture adheres to the disk member surface.

[0004]

In the conventional drag mechanism, grease is not used together with these materials in order to increase the frictional force between the disk members and obtain a large drag force with a small pressing force. It is desirable to do so. However, if grease is not used, drag scratching occurs as described above, and foreign matter (such as lint, cork dust, carbon powder, and metal powder) generated by abrasion between the disc members easily scatters from the drag mechanism. If the foreign matter scatters from the drag mechanism, the foreign matter may adhere to the tooth surface of the adjacent main gear or pinion gear and deteriorate the meshing feeling of the gear.

[0005] An object of the present invention is to provide a drag mechanism for a dual-bearing reel in which a large drag force can be obtained with a small pressing force.
Another object of the present invention is to maintain good gear engagement feeling.

[0006]

A drag mechanism for a dual-bearing reel according to a first aspect of the present invention is an operating member for screwing a rotation of a spool rotatably supported on a reel body of the dual-bearing reel in a line payout direction to a handle shaft. A mechanism that can be variably braked by the turning operation of the motor, and includes a first rotating member, a second rotating member, one or a plurality of disk members, and foreign matter scattering prevention means. The first rotating member is a member including a main gear, which is mounted on the handle shaft so as to be rotatable with respect to the reel body. The second rotating member is a member that is mounted on the handle shaft and is prevented from rotating with respect to the reel body in the spool reel-out direction. Here, in a dual-bearing reel in which the handle shaft is not allowed to rotate in the line pay-out direction, the second rotating member is non-rotatably mounted on the handle shaft, and in a dual-bearing reel in which the handle shaft is rotatable in the line pay-out direction. The second rotating member is mounted on the handle shaft such that the second rotating member cannot rotate in the line pay-out direction. The one or more disk members are disposed between the first rotating member and the second rotating member. The foreign matter scattering prevention means is provided on at least one outer peripheral side of the disk member and the two rotating members, and is a means for preventing the scattering of foreign matter generated by wear of the disk member and the two rotating members.

In this drag mechanism, when the spool is rotated in the line paying-out direction by pulling a fish or the like in a state where both rotating members and the respective disc members are pressed against each other by operating the operating member, the first rotating member, the second rotating member, One or more disk members disposed between the rotating members are relatively rotated while being pressed against each other, and the spool is braked via the main gear. At this time, foreign matter may be generated due to abrasion, and the foreign matter is prevented from being scattered by the scattering prevention means provided on at least one outer peripheral side of both the rotating member and the disk member. For this reason, the scattering of foreign substances can be suppressed without using grease on the entire surface, so that a large drag force can be obtained with a small pressing force, and the meshing feeling of the gear can be maintained satisfactorily.

A drag mechanism for a dual bearing reel according to a second aspect of the present invention is the mechanism according to the first aspect, wherein at least one of the one or more disk members is made of graphite.
In this case, since at least one disk member is made of graphite, the coefficient of friction hardly changes even when worn. Further, the drag force does not easily fluctuate even when worn, and the fluctuation of the drag performance due to aging is small. Further, the braking force when moisture adheres to the surface of the disk member is stabilized without applying grease to the entire surface of the disk member.

A drag mechanism for a dual-bearing reel according to a third aspect of the present invention is the drag mechanism according to the second aspect, wherein a plurality of disk members and both rotating members are made of graphite and stainless steel alternately. In this case, since it is not necessary to apply lubricating oil such as grease to the entire surface, fluctuations in drag performance due to temperature changes can be suppressed, and a high friction coefficient can be maintained, so that a large drag force can be easily obtained.

A drag mechanism for a dual-bearing reel according to a fourth aspect of the present invention is the mechanism according to any one of the first to third aspects, wherein the foreign matter scattering prevention means comprises at least one outer peripheral portion of both rotating members and one or more disk members. This is the grease layer formed on the substrate. In this case, grease is used,
Since the area of the grease layer is only the outer peripheral portions of both the rotating members or the disk members, that is, the outer peripheral edges and the outer peripheral end surfaces of the both rotating members or the disk members, a reduction in frictional force can be reduced, and a large drag with a small pressing force can be obtained. Power is gained.
In addition, foreign matter adheres to the grease layer formed on the outer peripheral portion and is prevented from being scattered, so that the meshing feeling of the gear can be favorably maintained. In addition, since the scattering of foreign matter can be prevented only by forming the grease layer, the structure of the foreign matter scattering preventing means is simple.

A drag mechanism for a dual-bearing reel according to a fifth aspect of the present invention is the mechanism according to any one of the first to third aspects, wherein one or more foreign matter scattering prevention means are provided between the first rotating member and the second rotating member. Is a cover portion provided so as to cover the disk member from the outer peripheral side. In this case, since the outer peripheral portion of one or a plurality of disk members between the first rotating member including the main gear and the second rotating member is covered with the cover portion, the outer peripheral portion is generated from a gap between both rotating members and the disk member. Foreign matter is hard to scatter outside.

A drag mechanism for a dual-bearing reel according to a sixth aspect of the present invention is the mechanism according to the fifth aspect, wherein the cover portion includes one or a plurality of disk members integrated with the second rotating member on the outer peripheral edge of the second rotating member. It is a tubular member formed to cover. In this case, by providing the cylindrical cover portion on the second rotating member, it is possible to reliably prevent the foreign matter from scattering from the gap between the two rotating members and the disk member.

A drag mechanism for a dual-bearing reel according to a seventh aspect of the present invention is the mechanism according to the fifth aspect, wherein the cover portion includes one or more disk members integrated with the first rotating member on the outer peripheral edge of the first rotating member. It is a tubular member formed to cover. In this case, by providing the cylindrical cover portion on the first rotating member, it is possible to reliably prevent the foreign matter from scattering from the gap between the rotating member and the disk member.

According to an eighth aspect of the present invention, there is provided a drag mechanism for a dual bearing reel according to any one of the first to third aspects, wherein the foreign matter scattering prevention means comprises one of the two rotating members and one of the opposing surfaces of the disk member. Is an annular concave portion formed on the outer peripheral edge of the light emitting element. In this case, even if foreign matter is generated from the gap between the two rotating members and one or a plurality of disk members, the foreign matter is stored in the annular concave portion and hardly scattered outside.

As shown in FIG. 1, a frame 5 having a pair of left and right side plates 10, 11 arranged at a predetermined interval and a plurality of support members 12 connecting the side plates 10, 11 is mounted on both sides of the frame 5. A first cover 13 and a second cover 14,
And a mechanism mounting plate 16 mounted on the second cover 14. The mechanism mounting plate 16 is arranged in contact with the side plate 11,
A space is formed between the mechanism mounting plate 16 and the second cover 14 for accommodating various mechanisms described below.

The frame 5 is obtained by die casting, and the second cover 14 is obtained by pressing a thin metal plate. Each of the pair of side plates 10, 11 and the first cover 13 has a circular shape when viewed from the side, and the outer peripheral surface is machined using, for example, a lathe. Second cover 14
As shown in FIGS. 2 and 3, the mechanism mounting plate 16 has a shape in which a part of a circular shape is protruded in a radial direction when viewed from the side.
The second cover 14 also protrudes outward in the axial direction around a mounting portion of a handle shaft 30 (described later).

The support member 12 is a plate-like member formed along the outer periphery of both side plates 10 and 11 and integrally formed with the both side plates 10 and 11. A pair of side plates 10 and 11 are connected at several places.
By integrally forming the side plates 10 and 11 and the plurality of support members 12 in this manner, even if a large load is applied to the reel body 1, deformation such as bending does not easily occur, and a reduction in winding efficiency is suppressed. . The outer peripheral portion of the support member 12 and the side plates 10, 1
1 is machined similarly to the first cover 13.

The rod mounting leg 4 is fixed to the lower supporting member 12. The rod mounting legs 4 are connected to the side plates 10 and 1 of the frame 5.
It is arranged along the center position F between the two. This center position F is also the center position of the yarn winding section of the spool 15.
The rear support member 12 is provided with a thumbrest 17 made of synthetic resin for holding the reel together with the fishing rod.

The thumb rest 17 is formed so as to be in contact with the upper portion and the rear portion of the support member 12, and the rear portion has the side plates 10,
11 protrudes radially outward, that is, rearward. The rear portion of the upper surface of the thumb rest 17 is inclined while projecting downward. Further, the left end and the right end of the rear portion of the upper surface of the thumbrest 17 gradually decrease as the amount of rearward projection increases toward the left.

A thumb rest 17 having such a shape is provided.
For example, by placing the thumb of the left hand on the thumb rest 17 and grasping the fishing rod RD with another finger and holding the reel together with the fishing rod RD, the fishing rod RD can be securely held together with the reel during vertical jigging or the like. The handle assembly 2 includes a crank arm 6 that is non-rotatably mounted at the tip of a handle shaft 30, and a crank arm 6 at one end of the crank arm 6.
And a rotation support 8 for rotatably attaching the handle 7 to the crank arm 6.
In the handle assembly 2, a portion where the handle shaft 30 is mounted on the crank arm 6 is separated from the reel body 1 from a portion where the rotation support portion 8 is mounted. That is, the rotation plane of the base end of the handle handle 7 is closer to the reel unit 1 side than the rotation plane of the fixed portion of the crank arm 6 to the handle shaft 30.

The crank arm 6 is a flat metal member that extends in the radial direction of the handle shaft 30 and is bent at two places. As shown in FIG. 2, the crank arm 6 is non-rotatably locked by a chamfered portion 30a formed at the tip of the handle shaft 30, and is fixed by a fixing nut 30b.
0 is detachably fixed. The spool 15 is shown in FIG.
As shown in FIG. 2, the first and second side plates 10 and 11 are rotatably arranged. The spool 15 includes a bobbin trunk 15a and flanges 15 integrally formed at both ends of the bobbin trunk 15a.
b. A spool shaft 25 passes through and is fixed to the center of the spool 15. The spool shaft 25 is the first
The cover 13 and the mechanism mounting plate 16 are rotatably supported via bearings 26a and 26b.

In the space between the mechanism mounting plate 16 and the second cover 14, torque from the handle assembly 2 is supplied to the spool 15.
Transmission mechanism 20 for transmitting to the
A clutch mechanism 21 provided in the
And a clutch operation mechanism 22 for turning on and off the clutch. The rotation transmission mechanism 20 includes a rotation control mechanism 23 for regulating torque when torque is reversely transmitted from the spool 15 to the handle assembly 2 side.
A centrifugal brake mechanism 2 for braking the spool 15 that freely rotates in the line payout direction is provided at the center of the side plate 11.
4 are arranged. The first cover 13 outside the side plate 10
Inside, a sound generating mechanism for generating sound when the spool 15 rotates, a lock mechanism for completely locking the spool 15 when the spool 15 gets stuck, etc. to facilitate thread breakage, and the like are arranged.

The rotation transmission mechanism 20 includes a handle shaft 30 having one end to which the handle assembly 2 is fixed, a main gear 31 connected to the other end of the handle shaft 30 via a rotation control mechanism 23, and a main gear 31. And a pinion gear 32 that meshes. The handle shaft 30 is disposed in parallel with the spool shaft 25, and one end is rotatably supported by the mechanism mounting plate 16. The main gear 31 is a handle shaft 3
0 so that the handle shaft 30
Can be connected to one end via a rotation control mechanism 23 so as not to rotate relatively. A ring-shaped storage space 31 d is formed in the inner peripheral portion of the main gear 31. In the main gear 31, two locking grooves 31b are formed at the edge of the storage space 31a. In such a configuration, when the clutch mechanism 21 is turned on, the torque from the handle assembly 2 is directly transmitted to the spool 15 via the main gear 31 and the pinion gear 32.

The clutch mechanism 21 includes a cylindrical pinion gear 3 slidably mounted on the outer periphery of a spool shaft 25.
2 and an engaging groove 32 arranged in a part of the pinion gear 32
a and a pin 33 arranged on the spool shaft 25. When the pinion gear 32 is slid along the spool shaft 25 to engage the engagement groove 32 a with the pin 33, rotational force is transmitted between the spool shaft 25 and the pinion gear 32. This state is a connection state (clutch-on state).
If the engagement between the engagement groove 32a and the pin 33 is released, the spool shaft 2
No rotational force is transmitted between the pinion gear 5 and the pinion gear 32.
This state is a disconnection state (clutch off state). In the clutch off state, the spool 15 rotates freely. The pinion gear 32 is urged by the clutch operating mechanism 22 in a direction in which the engagement groove 32a and the pin 33 are engaged, that is, in a clutch-on state. The clutch operating mechanism 22 includes a clutch lever 40 mounted on the second cover 14 of the reel body 1 so as to be swingable between a connected position and a disconnected position.

The rotation control mechanism 23 rotates the handle shaft 30 only in the yarn winding direction (prohibits the rotation in the yarn unwinding direction) and a roller type one-way clutch mechanism 70, and controls the rotation of the spool 15 in the yarn unwinding direction. It has a drag mechanism 72 for applying a set drag force, and a pawl type ratchet mechanism 74 for rotating the handle shaft 30 only in the line winding direction.

If only the reverse rotation (rotation in the line feeding direction) of the handle shaft 30 is prohibited, only the ratchet mechanism 74 may be provided and the one-way clutch mechanism 70 may be omitted. However, the ratchet mechanism 74 takes a certain amount of time for the operation of the ratchet pawl engaging and disengaging from the ratchet wheel. The roller-type one-way clutch mechanism 70 as described above is preferable in order to achieve the quick and smooth reverse rotation inhibition operation required for the fishing operation, and the ratchet mechanism 74 applies an excessive force that the one-way clutch mechanism 70 cannot bear. It is effective to bear.

As shown in FIG. 3, the drag mechanism 72 can adjust the drag force by operating the star drag 3 screwed to the handle shaft 30. The drag mechanism 72 includes a main gear (an example of a first rotating member) 31, a disk member 85 (an example of a second rotating member) arranged adjacent to the one-way clutch mechanism 70, and a rotation of the main gear 31. 5 drag discs 80 arranged between the members 85
And 84 and two disc springs 92 and 93 disposed between the one-way clutch mechanism 70 and the star drag 3. Between the disc spring 92 and the one-way clutch mechanism 70, a rolling bearing 90 and a washer 91 for rotatably supporting the handle shaft 30 are arranged. A washer 94 is arranged between the star drag 3 and the disc spring 93.

The drag disks 80 to 82 are stored in a storage space 31a in the main gear 31. The drag disk 80 is a graphite ring-shaped member, and is obtained by cutting a cylindrical rod-shaped graphite material. The drag disk 80 is disposed to face the main gear 31 and can be pressed against the main gear 31. The drag disk 81 is provided with a first rectangular portion 30 d formed on the handle shaft 30.
And has a square center hole 81a that is locked to the center hole 81a. Therefore, the drag disk 81 cannot rotate with respect to the handle shaft 30 and can rotate relative to the drag disk 80. Drag disk 81 is made of, for example, a stainless alloy. The drag disk 82 is a ring-shaped member made of graphite, and is obtained by cutting a cylindrical rod-shaped graphite material like the drag disk 80. The drag disk 82 is rotatable with respect to the handle shaft 30.

The handle shaft 30 has a first rectangular portion 3
A second rectangular portion 30e is formed at an interval on the left side of FIG. 3 of 0d, and a flange portion 30f is also formed on the second rectangular portion 30e. A ratchet wheel 74a, which constitutes a ratchet mechanism 74, is non-rotatably mounted on the second rectangular portion 30e. It is mounted so that it can be pressed against.

The drag disk 83 is a ring-shaped member made of a stainless alloy and is rotatable with respect to the handle shaft 30. Locking pieces 83 a extending toward the main gear 31 are formed at two opposing peripheral portions of the drag disk 83. The locking piece 83a is locked in the locking groove 31b of the main gear 31. As a result, the drag disk 8
3 rotates integrally with the main gear 31. The drag disk 84 is a ring-shaped member made of graphite, and is obtained by cutting a cylindrical rod-shaped graphite material like the drag disk 80. The drag disk 84 is rotatable with respect to the handle shaft 30.

The disk member 85 is a stainless steel ring-shaped member, and has an inner peripheral portion formed with an oval hole 85a that is non-rotatably locked to the chamfered portion 30a of the handle shaft 30. For this reason, the disk member 85 is
It cannot rotate with respect to 0. Further, locking concave portions 85b are formed at two opposing locations on the inner peripheral portion. An inner ring 86 constituting the one-way clutch mechanism 70 is non-rotatably connected to the locking recess 85b. At one end of the inner ring 86, a pair of locking projections 86a that are fitted into the locking recesses 85b project toward the disk member 85.
The other end of the inner ring 86 is in contact with the rolling bearing 90. Thus, the inner ring 86 rotates together with the handle shaft 30.

A grease layer 95 is formed on the outer peripheral portion of each of the drag disks 80 to 84 and the disk member 85, as shown by a thick line in FIG. The grease layer 95 causes foreign substances such as carbon powder and metal powder generated by wear of the main gear 31, the drag disks 80 to 84 and the disk member 85 to scatter outside the disk and adhere to the tooth surfaces of the main gear 31 and the pinion gear 32. It is provided in order to prevent that. The grease layer 95 is provided for each of the drag disks 80 to 8.
4 and outer peripheral edge 95a and outer peripheral end surface 9 of disc member 85
5b is formed by applying a thin layer of grease. When such a grease layer 95 is provided, foreign matter generated by abrasion is less likely to adhere to the grease layer 95 and scatter outside, and a reduction in the performance of gear engagement feeling can be suppressed. Further, since the grease is not applied to the entire surface of the drag disks 80 to 84 and the disk member 85, a decrease in frictional force can be suppressed, and a large drag force can be obtained with a small pressing force.

The disc springs 92 and 93 are arranged so that their peripheral edges come into contact with each other. The disc springs 92 and 93 are connected to the main gear 31, each of the drag disks 80 to 84, and the disk member 8.
5 is provided for adjusting the pressing force to the pressing member 5. next,
The operation of the reel will be described. Before fishing, the star drag 3 is rotated to adjust the drag force. When adjusting the drag force, a spring weigher or a weight having the same weight as the target fish is connected to the tip of the fishing line, and the connected scale or weight is pulled to generate a desired drag force. The star drag 3 is rotated.

When the star drag 3 is rotated clockwise in FIG. 3, the star drag 3 screwed to the handle shaft 30 moves axially in a direction approaching the reel body 1. As a result, the disc springs 92 and 93 bend and the washer 91 and the rolling bearing 9
0 and inner ring 86 at the base end side of handle shaft 30 (left side in FIG. 3)
Press Then, the pressing force of the main gear 31, the drag disks 80 to 84, and the disk member 85 increases, and the drag force increases. Conversely, when the star drag 3 is rotated counterclockwise, the star drag 3 moves to the distal end side of the handle shaft 30, and the main gear 31, each of the drag disks 80 to
The pressing force of the disk member 84 and the disk member 85 decreases, and the drag force decreases.

When the fishing line is paid out, the clutch mechanism 21 is brought into the clutch off state by the clutch lever 40. As a result, the spool 15 enters a free rotation state, and the spool 15 rotates in the line payout direction due to the weight of the jig (device), and the fishing line is paid out from the spool 15.
When the jig reaches the seabed, the handle assembly 2 is rotated in the line winding direction to start vertical jigging. When the handle assembly 2 is rotated in the line winding direction, the clutch is turned on by a clutch return mechanism (not shown).

When performing vertical jigging, for example, a rear end portion (not shown) of the fishing rod RD is sandwiched on the left side,
Place the thumb of the left hand on the thumb rest 17 fixed to the rear part of the reel body 1, hold the fishing rod with the remaining fingers, hold the reel and the fishing rod RD, and, while sucking the fishing rod RD with the left hand, handle the handle assembly 2 with the right hand. The pumping operation of grasping the handle 7 and rotating the handle shaft 30 at high speed is repeated.

When the handle assembly 2 is rotated in the line winding direction, the rotation of the handle assembly 2 is directly transmitted from the handle shaft 30 to the main gear 31 via the one-way clutch mechanism 70 and the drag mechanism 72. At this time, since the clutch mechanism 21 is in the ON state, the rotation of the main gear 31 is transmitted from the pinion gear 32 to the spool 15, and the fishing line is wound up. At this time, the one-way clutch mechanism 70 and the ratchet mechanism 74 allow rotation because the rotation is in the line winding direction.

When the fishing line is paid out by pulling a fish or the like, the rotation of the spool 15 is transmitted to the main gear 31.
The power is transmitted to the handle shaft 30 and the one-way clutch mechanism 70 via the drag mechanism 72. In the one-way clutch mechanism 70, the reverse rotation of the handle shaft 30 is prohibited. If the fish is weakly pulled, the spool 15 does not rotate and the fishing line is not pulled out. Then, when the fish is strongly pulled and the rotational force of the spool 15 is increased, the transmitted rotational force exceeds the drag force set by the drag mechanism 72. Then, the drag mechanism 72 causes the main gear 31 and the drag disc 80 to
Since the sliding of the disk member 84 and the disk member 85 occurs, the spool 15 including the main gear 31 starts rotating. At this time, a constant resistance, that is, a drag force always acts on the spool 15 from the drag mechanism 72.

Since a part of the drag disks 80 to 84 is made of graphite when the drag force is applied, the drag force hardly changes even when worn, and the change in the drag performance due to aging is small. Moreover, since it is not necessary to apply lubricating oil such as grease to the entire surface, fluctuations in drag performance due to temperature changes can be suppressed, and a high friction coefficient can be maintained, so that a large drag force can be easily obtained. Furthermore, even if foreign matter is generated due to abrasion, it is difficult for the foreign matter to adhere to the grease layer 95 and scatter outside. For this reason, it is possible to suppress a reduction in the gear meshing feeling due to the scattering of foreign matter.

[Other Embodiments] (a) In the above-described embodiment, the foreign matter scattering prevention means is realized by the grease layer 95. However, as shown in FIG. The part 96 may be provided to realize a foreign matter scattering prevention means.

Further, as shown in FIG.

The cover portion 97 extends to a position approaching the outer peripheral surface of the disk member 85, and a slight gap is formed with the disk member 85. As shown in FIG. 7, another cover member 100 may be interposed in the gap between the cover portion 97 and the disk member 85 to close the gap.

(B) As shown in FIG. 8, the main gear 31 and the stainless steel drag disk 81,
An annular groove 9 formed on the outer peripheral edge of the disk member 85 or 83
8, foreign matter scattering prevention means may be realized. In this case, even if foreign matter is generated from the gap between the opposed disks, it is difficult for the foreign matter to accumulate in the annular groove 98 and scatter outside. (C) In the above embodiment, a graphite material or a stainless steel alloy was used as the drag disk material. However, the present invention is not limited to this, and the drag disk material may be a carbon fiber reinforced resin, a phenol resin laminated material, a cork material, or the like. Other materials may be used.

(D) In the above embodiment, the drag mechanism 72 was operated by the star drag 3 extending radially.
The drag mechanism 72 may be operated by a lever-shaped operation member provided on the second cover. (E) In the above embodiment, the main gear 31 is rotatably mounted on the handle shaft 30.
The present invention is also applicable to a drag mechanism in which the disc member is non-rotatably connected to the handle shaft 30 and the disc member is mounted on the handle shaft so as to prevent rotation in the line feeding direction.

[0045]

According to the present invention, even if foreign matter is generated due to wear during drag operation, the foreign matter is prevented from being scattered by the scattering prevention means provided on at least one outer peripheral side of both the rotating member and the disk member. You. For this reason, the scattering of foreign substances can be suppressed without using grease on the entire surface, so that a large drag force can be obtained with a small pressing force, and the meshing feeling of the gear can be maintained satisfactorily.
