Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the figure, the same or equivalent parts are designated by the same reference numerals.

Embodiment 1.
FIG. 1 is a perspective view of a fishing reel according to the first embodiment of the present invention. This fishing reel is a double bearing reel 99 mainly used for lure fishing. Both bearing reels 99 include a reel main body 1, a handle 2 arranged on the side of the reel main body 1, and a drag adjusting star drag 3 arranged on the reel main body 1 side of the handle 2. A spool 12 around which a fishing line is wound is rotatably supported on the reel body 1. The spool 12 is arranged between the first side cover 6 and the second side cover 7. When the handle 2 is turned, the spool 12 can be rotated to wind the fishing line. The handle 2 has a plate-shaped arm portion 2a and a pair of handles 2b rotatably attached to both ends of the arm portion 2a.

The double bearing reel 99 is attached to the fishing rod so that the left front side faces the tip (front) of the fishing rod toward FIG. 1. The fishing line is usually stretched from the spool 12 to the left front side toward FIG. 1. In FIG. 1, the front left side is referred to as the front side of the reel body 1, and the back side of the right hand is referred to as the rear side. A clutch operating lever 17 is arranged behind the reel body 1. By operating the clutch operating lever 17, the clutch between the handle 2 and the spool 12 can be disengaged. A thumb rest 10 is mounted so as to surround the front side of the spool 12.

When the fishing line wound around the spool 12 is unwound by the casting operation, the spool 12 rotates. A spool braking device is provided inside the reel body 1 in order to prevent backlash during casting operation. An operation knob 65 for adjusting the braking force of the spool braking device is arranged on the first side cover 6 on the side opposite to the handle 2 of the reel body 1. By turning the operation knob 65, the braking force of the spool 12 can be adjusted.

FIG. 2 is a cross-sectional view of the fishing reel according to the first embodiment. Looking at FIG. 2 in the direction in which the characters stand upright, the top is the front and the bottom is the back. In FIG. 2, the braking device is omitted. The reel main body 1 has a frame 5 and a first side cover 6 and a second side cover 7 mounted on both sides of the frame 5. The frame 5 has a pair of first side plates 8 and second side plates 9 arranged so as to face each other at intervals, and a plurality of connecting portions (not shown) connecting the first side plates 8 and the second side plates 9. Have.

The second side cover 7 on the handle 2 side is fixed to the second side plate 9 with screws. The first side plate 8 on the opposite side of the handle 2 is formed with an opening 8a through which the spool 12 can pass. A brake case 50 is fitted in the first side cover 6 on the opposite side of the handle 2.

A spool 12, a level wind mechanism 15, and a clutch operating lever 17 are arranged in the frame 5. The level wind mechanism 15 is a mechanism for uniformly winding the fishing line around the spool 12.

A gear mechanism 18, a clutch mechanism 13, and a clutch engaging / disengaging mechanism 19 are arranged between the second side plate 9 of the frame 5 and the second side cover 7. The gear mechanism 18 transmits the rotational force from the handle 2 to the spool 12 and the level wind mechanism 15. The clutch engaging / disengaging mechanism 19 engages / disengages the clutch mechanism 13 in response to the operation of the clutch operating lever 17.

The spool 12 has a tubular boss portion 12c integrally formed on the inner peripheral side. The spool 12 is fixed, for example, by serration coupling so as not to rotate relative to the spool shaft 16 penetrating the boss portion 12c.

The spool shaft 16 penetrates the second side plate 9 and extends outward from the second side cover 7. The end of the spool shaft 16 near the handle 2 is rotatably supported by the bearing 72 with respect to the second side cover 7. The end of the spool shaft 16 near the first side cover 6 is rotatably supported by the brake case 50 by the bearing 71.

When the handle 2 is turned, the rotation is transmitted to the spool shaft 16 via the gear mechanism 18 and the clutch mechanism 13. The clutch mechanism 13 can be disengaged by operating the clutch operating lever 17. If the clutch mechanism 13 is disengaged, the spool shaft 16 and the spool 12 can freely rotate regardless of the handle 2. When the clutch mechanism 13 is disengaged and casting is performed, the spool 12 rotates freely and the fishing line is unwound.

The brake case 50 is formed with a cylindrical holding portion 51 extending toward the center of the spool 12. The bearing 71 is housed and held in the holding portion 51 of the brake case 50. An O-ring 82 is interposed between the outer peripheral surface of the bearing 71 and the inner peripheral surface of the holding portion 51.

FIG. 3 is an enlarged cross-sectional view of the bearing holding structure according to the first embodiment. The cylindrical holding portion 51 formed in the brake case 50 has a cylindrical inner peripheral surface, and has a size in which the bearing 71 is just fitted. The bearing 71 is housed and held in the holding portion 51. With the bearing 71 held, the outer peripheral surface of the bearing 71 and the inner peripheral surface of the holding portion 51 face each other. The spool shaft is inserted through the inner ring of the bearing 71 and is rotatably supported by the bearing 71.

A ring groove 81 into which the O-ring 82 is fitted is formed on the outer peripheral surface of the bearing 71 over the entire circumference. The O-ring 82 is fitted and held in the ring groove 81. An O-ring 82 is interposed between the outer peripheral surface of the bearing 71 and the inner peripheral surface of the holding portion 51. No groove is formed on the inner peripheral surface of the holding portion 51. An opening inclined surface 52 whose diameter increases toward the outside of the opening from the position where the bearing 71 is held is formed around the opening in which the bearing of the holding portion 51 is inserted.

The outer diameter of the open O-ring 82 is larger than the diameter of the inner peripheral surface of the holding portion 51, and the inner diameter of the O-ring 82 is smaller than the outer diameter of the bottom surface of the ring groove 81. The O-ring 82 is compressed in the radial direction while the O-ring 82 is fitted in the ring groove 81 and held on the inner peripheral surfaces of the bearing 71 and the holding portion 51. Vibration between the bearing 71 and the holding portion 51 is suppressed by the O-ring 82 interposed between the outer peripheral surface of the bearing 71 and the inner peripheral surface of the holding portion 51.

Since the ring groove 81 into which the O-ring 82 is fitted is formed on the outer peripheral surface of the bearing 71, it can be easily formed as compared with the case where the groove is formed on the inner peripheral surface of the cylinder. Then, the accuracy of the outer diameter of the bottom surface of the ring groove 81 and the width of the ring groove 81 can be improved as compared with the case where the groove is formed on the inner peripheral surface of the cylinder. As a result, there is no gap in the O-ring 82, and the amount of deformation of the O-ring 82 can be kept within the specified range. The O-ring 82 is not too tight to be inserted or damaged. According to the bearing holding structure of the first embodiment, the vibration absorption performance of the rotating shaft can be maintained and the assembling property can be improved.

Further, since the opening inclined surface 52 is formed in the opening of the holding portion 51, the O-ring 82 is not twisted or damaged when the bearing 71 fitted with the O-ring 82 is inserted into the holding portion 51. , Easy to insert into the holding portion 51.

4A to 4D are cross-sectional views showing an example of an open inclined surface of the bearing holding structure according to the first embodiment. 4A to 4D show one side of the cross section of the opening portion of the holding portion 51. The opening inclined surface 52 is formed around the opening of the holding portion 51, and its diameter increases from the position where the bearing 71 is held toward the outside of the opening. The opening inclined surface 52 is a rotating surface around the central axis of the holding portion 51.

The opening inclined surface 52 of FIG. 4A has an angle formed by the line of the opening inclined surface 52 and the central axis of 45 ° in a cross section passing through the central axis of the holding portion 51. The opening inclined surface 52 is not limited to 45 °. For example, as shown in FIG. 4B, the angle formed by the line of the opening inclined surface 52 and the central axis may be smaller than 45 °. In the opening inclined surface 52 of FIG. 4B, when the bearing 71 is inserted into the holding portion 51, the outer periphery of the O-ring 82 is compressed more gently than the opening inclined surface 52 of FIG. 4A.

The opening inclined surface 52 is not limited to a rotating surface having a straight cross section. For example, the opening inclined surface 52 in FIG. 4C is an arc whose cross-sectional shape is in contact with both the end surface line and the inner peripheral surface line of the holding portion 51. The opening inclined surface 52 in FIG. 4D has an arcuate cross-sectional shape and is in contact with the line of the inner peripheral surface of the holding portion 51, but is connected to the line of the end surface at an angle. The shape of the cross section of the opening inclined surface 52 is not limited to an arc having a constant curvature, but may be a curve whose curvature changes, such as an ellipse or a hyperbola. When the shape of the cross section of the opening inclined surface 52 is curved, it is desirable that it touches the line of the inner peripheral surface of the holding portion 51.

Embodiment 2.

FIG. 6 is a cross-sectional perspective view of the bearing holding structure according to the second embodiment. A spring groove 53 extending in the circumferential direction is formed on the inner peripheral surface of the holding portion 51 to hold the retaining spring 83 of the bearing 71. The retaining spring 83 is, for example, an annular spring formed by bending a wire rod into a polygon with one open portion. The retaining spring 83 may be, for example, a C ring.

A groove inclined surface 54 is formed over the entire circumference of the corner of the spring groove 53 on the side where the bearing 71 is held. The diameter of the groove inclined surface 54 increases from the position where the bearing 71 is held toward the opening into which the bearing 71 is inserted. The action of the groove inclined surface 54 is the same as that of the opening inclined surface 52. When the bearing 71 fitted with the O-ring 82 is inserted into the holding portion 51, the O-ring 82 is compressed and deformed by the opening inclined surface 52, and is inserted by sliding on the inner peripheral surface. The outer peripheral side of the O-ring 82 is once opened by the spring groove 53, but is compressed again by the groove inclined surface 54 and deformed.

Since the groove inclined surface 54 is formed in the spring groove 53, the O-ring 82 is not twisted or damaged when the bearing 71 fitted with the O-ring 82 is inserted further into the spring groove 53. , Easy to insert in the position to hold the bearing 71.

7A to 7D are cross-sectional views showing an example of a groove inclined surface of the bearing holding structure according to the second embodiment. 7A to 7D show one side of the cross section of the spring groove 53 portion of the holding portion 51. The groove inclined surface 54 is formed around the corner of the spring groove 53 on the side where the bearing 71 is held, and its diameter increases from the position where the bearing 71 is held toward the opening into which the bearing 71 is inserted. .. The groove inclined surface 54 is a rotating surface around the central axis of the holding portion 51.

The groove inclined surface 54 of FIG. 7A has an angle formed by the line of the groove inclined surface 54 and the central axis of 45 ° in a cross section passing through the central axis of the holding portion 51. The groove inclined surface 54 is not limited to 45 °. For example, as shown in FIG. 7B, the angle formed by the line of the groove inclined surface 54 and the central axis may be smaller than 45 °. In the groove inclined surface 54 of FIG. 7B, when the bearing 71 is inserted into the holding portion 51, the outer periphery of the O-ring 82 is compressed more gently than the groove inclined surface 54 of FIG. 7A.

The groove inclined surface 54 is not limited to a rotating surface having a straight cross section. For example, the groove inclined surface 54 in FIG. 7C is an arc whose cross-sectional shape is in contact with both the side line and the inner peripheral surface line of the spring groove 53. The groove inclined surface 54 in FIG. 7D has an arcuate cross-sectional shape and is in contact with a line on the inner peripheral surface of the holding portion 51, but is connected at an angle to a line on the side surface of the spring groove 53. .. The shape of the cross section of the groove inclined surface 54 is not limited to an arc having a constant curvature, but may be a curve whose curvature changes, such as an ellipse or a hyperbola. When the shape of the cross section of the groove inclined surface 54 is curved, it is desirable that it touches the line of the inner peripheral surface of the holding portion 51.

FIG. 8 is an enlarged cross-sectional view showing a modified example of the bearing holding structure according to the second embodiment. FIG. 8 is an enlarged cross-sectional view of a portion corresponding to FIG. 3 or FIG. 5 for the spool shaft of both bearing reels 99. In the example of FIG. 8, the holding portion 51 fitted to the first side plate 8 is formed with an opening open toward the outside of the first side plate. In the examples of FIGS. 3 and 5, the bearing 71 is inserted into the holding portion 51 from the side of the spool 12, whereas in the example of FIG. 8, the bearing 71 is on the side opposite to the spool 12 with respect to the holding portion 51. Is inserted from. The opening of the holding portion 51 is closed by the lid member 55 after the bearing 71 is inserted.

Since the groove inclined surface 54 is formed in the spring groove 53 as in the second embodiment, the O-ring 82 is inserted further into the spring groove 53 when the bearing 71 fitted with the O-ring 82 is inserted further into the spring groove 53. It is not twisted or damaged and can be easily inserted in the position where the bearing 71 is held.

In the structure of FIG. 8, instead of the retaining spring 83, for example, a spacer sandwiched between the lid member 55 and the outer ring of the bearing 71 is inserted, or the tip of the lid member 55 is extended so as to be in contact with the outer ring of the bearing 71. You may do it. In that case, the structure can be the same as that of the first embodiment in which the spring groove 53 is not formed.

As shown in FIGS. 3, 5 and 8, the bearing 71 is inserted into the holding portion 51 in the direction from the center to the end of the shaft, and is inserted in the direction from the end to the center of the shaft. In any case, the bearing holding structure of the first embodiment or the second embodiment can be adopted.

The rear end side of the spool shaft 102 is connected to the oscillating mechanism 115.

The handle 113 is a crank, and a drive gear 114 is attached to the crank shaft. The drive gear 114 is, for example, a face gear and meshes with the gear portion 131 of the pinion gear 103. The oscillating mechanism 115 rotates in synchronization with the pinion gear 103. When the oscillating mechanism 115 rotates, the spool shaft 102 is reciprocated in the front-rear direction.

A one-way clutch 105 is arranged between the pinion gear 103 and the accommodating member 104 so that the pinion gear 103 rotates in only one direction. The accommodating member 104 is fixed to the reel main body 101. The inner ring of the one-way clutch 105 fits into the pinion gear 103 and rotates together with the pinion gear 103. The outer ring of the one-way clutch 105 is fitted and fixed to the accommodating member 104.

The one-way clutch 105 is held by the lid member 106 in the internal space of the accommodating member 104. The cover plate 108 is attached in close contact with the surface of the lid member 106 facing the rotor 111 in the axial direction. Further, a rotor collar 107 formed in an annular shape around the outer circumference of the pinion gear 103 in the rotation direction is fitted to the pinion gear 103. A seal member 109 that seals the gap between the lid member 106 and the rotor collar 107 is attached to the front surface of the lid member 106.

The pinion gear 103 has a bearing 75 at the rear end close to the oscillating mechanism 115 and a bearing 76 at the intermediate portion, and is rotatably supported by the reel body 101. The central portion of the rotor 111 is rotatably supported by a bearing 77 with respect to the spool shaft 102. The outer ring of the bearing 77 rotates together with the rotor 111. The inner ring of the bearing 77 slides in the front-rear direction with respect to the spool shaft 102, but does not rotate with respect to the spool shaft 102.

A bearing 78 and a bearing 79 are arranged between a member of the drag mechanism 116 that does not rotate with respect to the spool shaft 102 and a member that rotates with the spool 112 with respect to the spool shaft 102, and the spool 112 with respect to the spool shaft 102. Is rotatably supported. In the bearing 78 and the bearing 79, the outer ring rotates with respect to the spool shaft 102 together with the spool 112, and the inner ring is fixed to the spool shaft 102.
