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

Embodiment 1
FIG. 1 is a perspective view of a fishing reel according to a first embodiment of the present invention. This fishing reel is a double bearing reel 99 mainly used for lure fishing. The dual-bearing reel 99 includes a reel body 1, a handle 2 disposed on the side of the reel body 1, and a drag drag star drag 3 disposed on the reel body 1 side of the handle 2. A spool 12 on which a fishing line is wound is rotatably supported by the reel body 1. The spool 12 is disposed 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 take up the fishing line. The handle 2 includes a plate-like arm 2a and a pair of grips 2b rotatably mounted on both ends of the arm 2a.

  The dual bearing reel 99 is attached to the fishing rod so that the left front side in FIG. 1 faces the tip (forward) of the fishing rod. The fishing line is usually stretched from the spool 12 to the left front side in FIG. In FIG. 1, the left front side is referred to as the front of the reel unit 1, and the right back side is referred to as the rear. A clutch control lever 17 is disposed at the rear of the reel unit 1. When the clutch control lever 17 is operated, 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 fed out by the casting operation, the spool 12 is rotated. A spool braking device is provided inside the reel body 1 to prevent backlash during casting operation. An operation knob 65 for adjusting the braking force of the spool braking device is disposed on the first side cover 6 opposite to the handle 2 of the reel body 1. By turning the operation knob 65, the force for braking the spool 12 can be adjusted.

  FIG. 2 is a cross-sectional view of the fishing reel according to the first embodiment. The upper side is the front, the lower side is the rear, looking at FIG. The braking device is omitted in FIG. The reel unit 1 includes a frame 5 and first and second side covers 6 and 7 mounted on both sides of the frame 5. The frame 5 includes a pair of first side plates 8 and second side plates 9 arranged to face each other at an interval, 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 a screw. An opening 8 a through which the spool 12 can pass is formed in the first side plate 8 opposite to the handle 2. A brake case 50 is fitted in the first side cover 6 on the opposite side of the steering wheel 2.

  In the frame 5, a spool 12, a level wind mechanism 15, and a clutch operation lever 17 are disposed. 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 engagement / disengagement mechanism 19 are disposed 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 engagement / disengagement mechanism 19 engages / disengages the clutch mechanism 13 in response to the operation of the clutch operation lever 17.

  The spool 12 has a cylindrical boss 12 c 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 passing through the boss 12 c.

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

  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. When the clutch control lever 17 is operated, the clutch mechanism 13 can be disengaged. If the clutch mechanism 13 is disengaged, the spool shaft 16 and the spool 12 can freely rotate independently of the handle 2. When the clutch mechanism 13 is disengaged and casting is performed, the spool 12 is freely rotated and the fishing line is drawn out.

  The brake case 50 is formed with a cylindrical holding portion 51 extending toward the center of the spool 12. The bearing 71 is accommodated and held in the holding portion 51 of the brake case 50. An O-ring 82 intervenes 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 surface on the inner peripheral surface, and has a size in which the bearing 71 is just fitted. The bearing 71 is housed and held in the holder 51. While the bearing 71 is 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 into the inner ring of the bearing 71 and is rotatably supported by the bearing 71.

  A ring groove 81 in which the O-ring 82 is fitted is formed on the entire outer circumference of the bearing 71. The O-ring 82 is fitted and held in the ring groove 81. An O-ring 82 intervenes between the outer peripheral surface of the bearing 71 and the inner peripheral surface of the holding portion 51. A groove is not formed on the inner peripheral surface of the holding portion 51. An opening inclined surface 52 whose diameter increases from the position where the bearing 71 is held to the outside of the opening is formed around the opening where 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 of the ring groove 81. In a state in which 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, the O-ring 82 is compressed in the radial direction. The vibration of 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.

  The ring groove 81 into which the O-ring 82 is fitted is formed on the outer peripheral surface of the bearing 71, so it can be formed more easily than forming a groove on the cylindrical inner peripheral surface. Further, 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 forming the groove in the cylindrical inner peripheral surface. As a result, no gap is formed in the O-ring 82, and the amount of deformation of the O-ring 82 can be kept within the specified range. Also, 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 absorbing performance of the rotating shaft can be maintained, and the assemblability can be improved.

  Furthermore, since the opening inclined surface 52 is formed at 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.

  FIG. 4A to FIG. 4D are cross-sectional views showing an example of the opening inclined surface of the bearing holding structure according to the first embodiment. In FIG. 4A to FIG. 4D, one side of the cross section of the opening portion of the holding portion 51 is shown. 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 to the outside of the opening. The opening inclined surface 52 is a rotation surface around the central axis of the holding portion 51.

  The opening inclined surface 52 of FIG. 4A has a 45 ° angle between the line of the opening inclined surface 52 and the central axis in a cross section passing through the central axis of the holding portion 51. The opening slope 52 is not limited to 45 °. For example, as shown in FIG. 4B, the angle between 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 rotational surface having a straight cross section. For example, the opening inclined surface 52 of FIG. 4C is a circular arc in which the shape of the cross section is in contact with both the line of the end face of the holding portion 51 and the line of the inner circumferential surface. The shape of the cross section of the opening inclined surface 52 of FIG. 4D is a circular arc, and is in contact with the line of the inner peripheral surface of the holding portion 51, but is connected at an angle to the line of the end surface. The shape of the cross section of the opening inclined surface 52 is not limited to an arc having a constant curvature, and may be a curve whose curvature changes like an ellipse or a hyperbola. When the shape of the cross section of the opening inclined surface 52 is a curved line, it is desirable to be in contact with the line of the inner peripheral surface of the holding portion 51.

Second Embodiment
FIG. 5 is an enlarged cross-sectional view of a bearing holding structure according to Embodiment 2 of the present invention.

The bearing 71, the ring groove 81, the O-ring 82 and the opening inclined surface 52 are the same as in the first embodiment.

  FIG. 6 is a cross-sectional perspective view of the bearing holding structure according to the second embodiment. A circumferentially extending spring groove 53 for holding the retaining spring 83 of the bearing 71 is formed on the inner peripheral surface of the holding portion 51. The retaining spring 83 is, for example, an annular spring formed by bending a wire to form an open polygon at one point. 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 which the bearing 71 is held. The groove inclined surface 54 has a diameter increasing from the position where the bearing 71 is held to the opening where the bearing 71 is inserted. The action of the groove slope 54 is similar to that of the opening slope 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 circumferential surface. The O-ring 82 is once released on the outer peripheral side by the spring groove 53, but is compressed again by the groove slope 54 to be deformed.

  Since the grooved inclined surface 54 is formed in the spring groove 53, the O-ring 82 is not twisted or damaged when the bearing 71 having the O-ring 82 fitted therein is inserted further from the spring groove 53. , It is easy to insert in the position which holds bearing 71.

  FIGS. 7A to 7D are cross-sectional views showing examples of groove slopes of the bearing holding structure according to the second embodiment. In FIG. 7A to FIG. 7D, one side of the cross section of the portion of the spring groove 53 of the holding portion 51 is shown. 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 the diameter increases from the position where the bearing 71 is held toward the opening where the bearing 71 is inserted. . The groove inclined surface 54 is a rotation surface around the central axis of the holding portion 51.

  The groove inclined surface 54 of FIG. 7A has a 45 ° angle between the line of the groove inclined surface 54 and the central axis in a cross section passing through the central axis of the holder 51. The groove slope 54 is not limited to 45 °. For example, as shown in FIG. 7B, the angle between the line of the groove slope 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 rotational surface having a straight cross section. For example, the groove slope 54 in FIG. 7C is an arc whose cross-sectional shape is in contact with both the side line of the spring groove 53 and the line of the inner circumferential surface. The groove inclined surface 54 in FIG. 7D has a circular arc in cross section and is in contact with the line of the inner peripheral surface of the holding portion 51 but is connected at an angle to the line of the side surface of the spring groove 53 . The shape of the cross section of the groove slope 54 is not limited to an arc having a constant curvature, and may be a curve whose curvature changes like an ellipse or a hyperbola. When the shape of the cross section of the groove inclined surface 54 is a curved line, it is desirable to be in contact with the line of the inner peripheral surface of the holding portion 51.

  FIG. 8 is an enlarged sectional view showing a modification 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 5 with respect to the spool shaft of the dual bearing reel 99. As shown in FIG. In the example of FIG. 8, an opening opened toward the outside of the first side plate is formed in the holding portion 51 fitted to the first side plate 8. While the bearing 71 is inserted into the holding portion 51 from the side of the spool 12 in the examples of FIGS. 3 and 5, the bearing 71 is on the side opposite to the spool 12 with respect to the holding portion 51 in the example of FIG. Is inserted from The opening of the holding portion 51 is closed by the lid member 55 after the bearing 71 is inserted. For example, a screw is formed on the outer periphery of the lid member 55, and the lid member 55 is screwed into the holding portion 51.

  Also in the example of FIG. 8, the ring groove 81 is formed on the outer peripheral surface of the bearing 71, and the O-ring 82 is fitted and held in the ring groove 81. In the holding portion 51, an opening inclined surface 52 whose diameter increases from the position where the bearing 71 is held to the outside of the opening is formed around the opening into which the bearing 71 is inserted. A circumferentially extending spring groove 53 for holding the retaining spring 83 is formed on the inner peripheral surface of the holding portion 51. Then, on the corner of the side where the bearing 71 of the spring groove 53 is held, a groove inclined surface 54 whose diameter increases from the position where the bearing 71 is held toward the opening where the bearing 71 is inserted is formed It is done.
