Embodiment 1

1 is a perspective view of a fishing reel according to Embodiment 1 of the present invention. This fishing reel is a double-bearing reel 99 mainly used for lure fishing. The double bearing reel 99 includes a reel unit 1, a handle 2 disposed sideways of the reel unit 1, and a drag disposed on the reel unit 1 side of the handle 2, And a star drag 3 for adjustment. In the reel unit 1, a spool 12 to which a fishing line is wound is rotatably supported. The spool 12 is disposed between the first side cover 6 and the second side cover 7. When the handle 2 is turned, the fishing line can be wound by rotating the spool 12. The handle 2 has a plate-shaped arm portion 2a and a pair of knobs 2b rotatably mounted on both ends of the arm portion 2a.

The both bearing reels 99 are attached to the fishing rods so that the left frontmost side in the direction of looking in Fig. 1 faces the front end (front) of the fishing rod. The fishing line extends from the normal (normal) spool 12 to the left most front side in the direction as viewed in Fig. In Fig. 1, the leftmost front side is referred to as the front side of the reel body 1, and the innermost inside side is referred to as the rear side (rear side). A clutch operation lever 17 is disposed at the rear of the reel unit 1. [ When the clutch operating 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 released by the casting operation, the spool 12 rotates. In order to prevent backlash during casting operation, a spool braking device is provided inside the reel unit 1. [ An operation knob 65 for adjusting the braking force of the spool braking device is disposed 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 force for braking the spool 12 can be adjusted.

2 is a cross-sectional view of a fishing reel according to the first embodiment. Fig. 2 shows the front side in the direction in which the characters are erected and the rear side in the lower side. In Fig. 2, the braking device is omitted. The reel unit 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 includes a pair of first side plates 8 and a second side plate 9 disposed so as to face each other with a space therebetween and a pair of first side plates 8 and second side plates 9 connecting the first side plate 8 and the second side plate 9 It has multiple connections that do not exist.

The second side cover 7 on the handle 2 side is fixed to the second side plate 9 with screws. An opening 8a 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) opposite to the handle (2).

In the frame 5, a spool 12, a level winding mechanism 15, and a clutch operation lever 17 are disposed. The level wind mechanism 15 is a mechanism for uniformly winding fishing line on the spool 12. [

A gear mechanism 18, a clutch mechanism 13 and a clutch mechanism 19 are disposed between the second side plate 9 and the second side cover 7 of the frame 5 . The gear mechanism 18 transfers the rotational force from the handle 2 to the spool 12 and the level winding mechanism 15. The clutch mechanism 19 engages the clutch mechanism 13 in accordance with the operation of the clutch operation lever 17. [

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

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

When the handle 2 is turned, its rotation is transmitted to the spool shaft 16 through the gear mechanism 18 and the clutch mechanism 13. When the clutch operating lever 17 is operated, the clutch mechanism 13 can be disengaged. When the clutch mechanism 13 is disengaged, the spool shaft 16 and the spool 12 can freely rotate irrespective of the handle 2. When the clutch mechanism 13 is disengaged and cast, the spool 12 freely rotates to release the fishing line.

In the brake case 50, a normal holding portion 51 extending toward the center of the spool 12 is formed. The bearing 71 is received and held in the holding portion 51 of the brake case 50. An O-ring 82 is interposed between the outer circumferential surface of the bearing 71 and the inner circumferential surface of the holding portion 51.

3 is an enlarged cross-sectional view of the bearing holding structure according to the first embodiment. The normal holding portion 51 formed in the brake case 50 has a cylindrical surface with an inner peripheral surface and a bearing 71 precisely fitted therein. The bearing 71 is received and held in the holding portion 51. The outer peripheral surface of the bearing 71 and the inner peripheral surface of the holding portion 51 face each other with the bearing 71 held. The spool shaft is inserted into the inner ring of the bearing 71 and is rotatably supported by a bearing 71. [

On the outer peripheral surface of the bearing 71, there is formed a ring groove 81 through which an O-ring 82 is inserted. The O-ring 82 is sandwiched between the ring grooves 81. An O-ring 82 is interposed between the outer circumferential surface of the bearing 71 and the inner circumferential surface of the holding portion 51. Grooves are not formed on the inner peripheral surface of the holding portion 51. [ An opening slope 52 is formed around the opening in which the bearing of the holding portion 51 is inserted so that the diameter becomes larger toward the outside of the opening from the position where the bearing 71 is held.

The outer diameter of the O-ring 82 in the opened state 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 in a state where the O-ring 82 is fitted in the ring groove 81 and is held on the inner peripheral surface of the bearing 71 and the holding portion 51. 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. [

Since the ring groove 81 in which the O-ring 82 is fitted is formed on the outer peripheral surface of the bearing 71, the ring groove 81 can be easily formed as compared with a case where grooves are formed on a normal inner peripheral surface. The degree of the outer diameter of the bottom face 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 normal inner peripheral face. As a result, no gap is formed in the O-ring 82, and the amount of deformation of the O-ring 82 can be set within a prescribed range. Then, the O-ring 82 is too tight to be inserted or damaged. According to the bearing holding structure of the first embodiment, the vibration absorbing performance of the rotary shaft can be maintained and the assembling property can be improved.

Further, since the opening slope 52 is formed in the opening of the holding portion 51, when the bearing 71 including the O-ring 82 is inserted into the holding portion 51, the O-ring 82 is twisted It is easy to insert into the holding portion 51 without being damaged or damaged.

4A to 4D are cross-sectional views showing an example of an opening slope of the bearing holding structure according to the first embodiment. 4A to 4D show one side (one side) of the cross section of the opening portion of the holding portion 51. Fig. The opening slope 52 is formed around the opening of the holding portion 51 and has a larger diameter toward the outside of the opening from the position where the bearing 71 is held. The opening slope 52 is a rotation surface around the central axis of the holding portion 51.

4A has an angle formed by a line and a central axis of the opening slope 52 at an angle of 45 DEG in a cross section passing through the central axis of the holding portion 51. [ The opening slope 52 is not limited to 45 degrees. For example, as shown in FIG. 4B, the angle between the line and the central axis of the opening slope 52 may be made smaller than 45 degrees. 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 slope 52 of FIG. 4A.

The opening slope 52 is not limited to a straight-line-turning surface. For example, the opening slope 52 in Fig. 4C is an arc in which the shape of the cross section is tangent to both the line of the end face of the holding portion 51 and the line of the inner circumferential face. The opening slope 52 in Fig. 4D has an arc-shaped 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 end surface. The shape of the cross section of the opening slope 52 is not limited to an arc having a constant curvature but may be curved such that the curvature changes like an ellipse or a hyperbola. In the case where the shape of the cross section of the opening slope 52 is a curved line, it is preferable to contact the line of the inner peripheral surface of the holding portion 51.

Embodiment 2 Fig.

5 is an enlarged sectional view of a bearing holding structure according to a second embodiment of the present invention. The bearing retention structure of the second embodiment is formed with a spring groove 53 in which the retaining spring 83 of the bearing 71 is caught in the inner peripheral surface of the retaining portion 51 in addition to the structure of the first embodiment. The bearing 71, the ring groove 81, the O-ring 82 and the opening slope 52 are the same as those in the first embodiment.

6 is a cross-sectional perspective view of the bearing holding structure according to the second embodiment. On the inner circumferential surface of the holding portion 51 is formed a spring groove 53 extending in the circumferential direction for holding the slip prevention spring 83 of the bearing 71. The drop prevention spring 83 is, for example, an annular spring formed by bending a wire material to form a polygon with one open portion. The drop prevention spring 83 may be, for example, a C ring.

A groove sloping surface 54 is formed around the entire periphery of the corner of the spring groove 53 on the side where the bearing 71 is held. The groove slope 54 has a larger diameter 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 face 54 is the same as that of the opening inclined face 52. [ When the bearing 71 including 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 slidably inserted into the inner peripheral surface. The O-ring 82 is once compressed and deformed at the groove slope 54, although the outer circumferential side is opened at one end in the spring groove 53.

The O-ring 82 is twisted when the bearing 71 including the O-ring 82 is further inserted into the spring groove 53. Therefore, It is easy to insert the bearing 71 at a position where the bearing 71 is held.

7A to 7D are cross-sectional views showing an example of a groove inclined surface of a bearing retention structure according to the second embodiment. Figs. 7A to 7D show one side of the section of the portion of the spring groove 53 of the holding portion 51. Fig. The groove slope 54 is formed around the corner of the side where the bearing 71 is held on the side of the spring groove 53 and extends from the position where the bearing 71 is held toward the opening where the bearing 71 is inserted, . The groove slope 54 is a rotation surface around the center axis of the holding portion 51.

7A has an angle formed by the line of the groove slope 54 and the central axis at an angle of 45 DEG in a cross section passing through the center axis of the holding portion 51. [ The groove slope 54 is not limited to 45 degrees. For example, as shown in FIG. 7B, the angle between the line and the central axis of the groove slope 54 may be smaller than 45 degrees. 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 sloping face 54 of FIG. 7A.

The groove slope 54 is not limited to a straight-line-turning surface. For example, the groove slope 54 in Fig. 7C is an arc in which the shape of the cross section is tangent to both the line on the side surface of the spring groove 53 and the line on the inner circumferential surface. 7D has an arc shape in cross section and is in contact with the line of the inner circumferential 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 but may be a curved line such as an ellipse or a hyperbola that changes its curvature. When the cross-section of the groove slope 54 is a curved line, it preferably touches the line of the inner peripheral surface of the holding portion 51.

8 is an enlarged cross-sectional view showing a modified example of the bearing holding structure according to the second embodiment. 8 is an enlarged sectional view of a portion corresponding to Fig. 3 or Fig. 5 with respect to the spool shaft of the double-bearing reel 99. 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 which is sandwiched by the first side plate 8. 3 and 5, the bearing 71 is inserted into the holding portion 51 from the spool 12 side, whereas in the example of Fig. 8, the bearing 71 is inserted into the holding portion 51 with respect to the holding portion 51, (12). The opening of the holding portion 51 is closed by the lid member 55 after the bearing 71 is inserted. The lid member 55 is formed, for example, on the outer periphery of the cover member 55 and is engaged with the holding portion 51.

8, a ring groove 81 is formed on the outer peripheral surface of the bearing 71, and the O-ring 82 is held in the ring groove 81. An opening slope 52 is formed in the holding portion 51 around the opening into which the bearing 71 is inserted so that the diameter becomes larger toward the outside of the opening from the position where the bearing 71 is held. On the inner circumferential surface of the holding portion 51, there is formed a spring groove 53 extending in the circumferential direction for holding the slip-off preventing spring 83. A groove slope 54 (see FIG. 5) is formed on the entire circumference of the corner of the spring groove 53 on the side where the bearing 71 is held, from the position where the bearing 71 is held to the opening where the bearing 71 is inserted. Is formed.

Since the ring groove 81 in which the O ring 82 is sandwiched is formed on the outer peripheral surface of the bearing 71 in the same manner as in Embodiments 1 and 2, . The degree of the outer diameter of the bottom face 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 normal inner peripheral face. As a result, no gap is formed in the O-ring 82, and the amount of deformation of the O-ring 82 can be set within a prescribed range. Further, since the opening slope 52 is formed in the opening of the holding portion 51, when the bearing 71 including the O-ring 82 is inserted into the holding portion 51, the O-ring 82 is twisted It is easy to insert into the holding portion 51 without being damaged or damaged.

Since the groove slope 54 is formed in the spring groove 53 as in the second embodiment, when the bearing 71 including the O-ring 82 is inserted further into the spring groove 53 , It is easy to insert the bearing 71 in a position where the bearing 71 is held without the O-ring 82 being twisted or damaged.

8, for example, a spacer inserted between the lid member 55 and the outer ring of the bearing 71 may be inserted, or the spacer may be inserted into contact with the outer ring of the bearing 71 The tip of the lid member 55 may be extended. In this case, a structure similar to that of Embodiment 1 in which the spring groove 53 is not formed can be employed.

As shown in Figs. 3, 5 and 8, there is a structure in which the bearing 71 is inserted into the holding portion 51 in the direction from the center to the end of the shaft, The bearing holding structure according to the first embodiment or the second embodiment can be employed.

It is not limited to the bearing 71 of the spool shaft with respect to both bearing reels 99 that the bearing retention structure of the first or second embodiment can be employed. For example, the bearing holding structure according to the first or second embodiment can be applied to a structure for holding the bearing 72 supporting the handle 2 side of the spool shaft 16 shown in Fig. A bearing 73 for supporting a pinion for transmitting rotation to the spool shaft 16 via the clutch mechanism 13 or a bearing 73 for supporting a pinion shaft of the handle 2 or the gear wheel 18 (See FIG.

Embodiment 3:

Embodiment 3 shows an example in which the bearing retention structure of Embodiment 1 or 2 is applied to a fishing reel other than a double-bearing reel. 9 is a cross-sectional view of a fishing reel according to Embodiment 3 of the present invention. The fishing reel of the third embodiment is a spinning reel 100. 9 shows an example of a section of the spinning reel 100. As shown in Fig.

The spinning reel 100 is attached to a fishing rod so that the left direction in the direction of looking in Fig. 9 is directed toward the front end (front side) of the fishing rod. The spinning reel 100 includes a reel unit 101, a rotor 111, a spool 112, and a handle 113. A fishing line (not shown) wound on the spool 112 is discharged forward, that is, leftward in Fig.

The rotor 111 rotates by turning the crank handle 113. When the handle 113 is turned, the spool 112 reciprocates in the front-rear direction in synchronization with the rotation of the rotor 111. [ With such an operation, the fishing line being released is guided by the rotor 111 and wound evenly on the cylindrical surface of the spool 112. [

The rotor 111 is fitted to the mounting portion 132 of the pinion gear 103 and is fixed to the pinion gear 103 and rotates together with the pinion gear 103. The pinion gear 103 is rotatably supported on the reel unit 101 around the center of rotation of the drive shaft. The pinion gear 103 is normally hollow. The spool shaft 102 is disposed through the pinion gear 103. The spool shaft 102 and the pinion gear 103 relatively rotate and reciprocate. On the front end side of the spool shaft 102, a spool 112 is mounted via a drag mechanism 116. 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 crankshaft. The drive gear 114 is, for example, a face gear, which is engaged 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 reciprocates in the front-rear direction.

A one-way clutch 105 is disposed between the pinion gear 103 and the housing member 104 so that the pinion gear 103 rotates only in one direction. The housing member 104 is fixed to the reel unit 101. The inner ring of the one-way clutch 105 is engaged with 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 housing member 104.

The one-way clutch 105 is held in the inner space of the cover member 106 and the housing member 104. The cover plate 108 is mounted in close contact with the surface of the lid member 106 facing the rotor 111 in the axial direction. A rotor collar 107 formed in an annular shape in a line around the outer periphery of the pinion gear 103 in the rotational direction is fitted to the pinion gear 103. A seal member 109 for sealing 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 is rotatably supported at the rear end closer to the oscillating mechanism 115 by a bearing 75 and at an intermediate portion by a bearing 76 to the reel body 101. [ The center portion of the rotor 111 is supported by a bearing 77 so as to be rotatable with respect to the spool shaft 102. In the bearing 77, the outer ring 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 provided between a member of the drag mechanism 116 that does not rotate with respect to the spool shaft 102 and a member that rotates together with the spool 112 with respect to the spool shaft 102 And the spool 112 is rotatably supported with respect to the spool shaft 102. As shown in Fig. The bearing 78 and the bearing 79 are rotated with respect to the spool shaft 102 together with the spool 112 and the inner ring is fixed with respect to the spool shaft 102.

The bearing holding structure according to the first or second embodiment can be applied to the holding structure of the bearings 75, 76, 77, 78, In the case where the slip-off preventing spring 83 is not used, the bearing holding structure of the first embodiment can be employed. That is, a ring groove 81 is formed on the outer periphery of the bearings 75, 76, 77, 78, 79, and the O-ring 82 is held in the ring groove 81. Further, an opening slope 52 is formed around the opening of the holding portion for holding the bearings 75, 76, 77, 78, and 79 into which the bearings 75, 76, 77, 78 and 79 are inserted.

In the bearings 77, 78, and 79, the outer ring rotates, but the vibration caused by the relative rotation of the inner ring and the outer ring can be suppressed. Since the outer circumferential surface of the bearing 76 is held in the radial direction on the inner circumferential surface of the holding portion 76, the inner circumferential surface of the O-ring (the outer circumferential surface of the bearing 76 is not opposed to the outer circumferential surface of the bearing 76) 82) has the effect. In the case of the holding portion of the bearing 76, the degree of the groove is higher when the ring groove 81 is formed on the outer peripheral surface of the bearing 76 than the groove of the O-ring 82 is formed on the inner peripheral surface of the holding portion .

In the case of using the anti-slip springs 83, the bearing holding structure of the second embodiment can be employed. That is, in addition to the ring groove 81 and the O-ring 82, the spring retaining groove 53 for retaining the retaining spring 83 is formed in the retaining portion, and the bearings 75, 76, 77 of the spring groove 53 , 78, and 79 are held, the groove slope 54 is formed.

The bearing holding structure of the first or second embodiment is not limited to the structure in which the bearing that rotatably supports the handle shaft 130 of the handle 113 with respect to the reel unit 101 is held, Can be used. In addition, the bearing retention structure of the first or second embodiment can be applied to the rotating shaft of the fishing reel as a whole, without being limited to both bearing reels and spinning reels.
