A sealing member (for example, O-ring 165C) that prevents liquid from entering the space,
To prepare for.

By sandwiching the seal member between the first side portion and the second side portion at a position overlapping the battery in the height direction of the first side portion, the thickness of the entire battery case can be suppressed. As a result, a thin battery case can be obtained. In particular, the battery case can be made thinner than sandwiching the seal member between the first side portion and the second side portion at a position that does not overlap with the battery in the height direction of the first side portion.

Further, both the first side portion and the second side portion have a tubular shape.
The second side portion may be located outside the first side portion (for example, see FIG. 5).

With this configuration, even if the sealing member deteriorates and a liquid enters between the first side portion and the second side portion, the liquid must not travel between the first side portion and the second side portion. Since it does not reach the storage space, it is difficult for the liquid to enter the storage space.

Further, a part of the battery terminals (for example, the positive electrode terminal 165D and the negative electrode terminal 165E) that come into contact with the electrodes of the battery may be embedded in the case body.

With this configuration, it is not necessary to provide a battery terminal board (a board on which the battery terminal is mounted), and the thickness of the battery case can be reduced by the amount of the board, and the thickness can be reduced.

The fishing reel according to the second aspect of the present invention (for example, both bearing reels 100) includes a battery case of any one of the above fishing reels.

With this configuration, a fishing reel having a thin battery case can be obtained, and for example, the accommodating portion of the battery case of the fishing reel can be miniaturized.

According to the present invention, it is possible to provide a thin battery case and a fishing reel provided with the battery case.

(For example, when pressed for a short time, the power is turned on or off, and when pressed for a long time, the water depth is reset).

Returning to the reference of FIGS. 1 to 5, the detailed structure of the battery case 165 will be described. In the following description, the direction of the cover 162 (left side when viewed from the user of the fishing rod to which both bearing reels 100 are attached) is referred to as "up", and the direction of the spool 140 (right side when viewed from the user) is referred to as "down". ..

As shown in FIG. 2 and the like, the battery case 165 includes a case body 165A, a lid 165B, an O-ring 165C (omitted in FIG. 3), a positive electrode terminal 165D (FIG. 5, omitted in other figures), and a negative electrode terminal. 165E (FIG. 5) and. The battery case 165 is arranged inside the cover 162, and when the cover 162 is removed, the battery case 165 protrudes from the surroundings.

The case body 165A has a circular bottom portion 165AA, a cylindrical side portion 165AB projecting upward from the bottom portion and surrounding the bottom portion 165AA, and three grooves protruding upward from the side portion 165AB to form a bayonet groove BM. A forming unit 165AC and the like are provided. The bottom portion 165AA and the side portion 165AB form an accommodation space S for accommodating the button type battery 200. Each of the three bayonet grooves BM has one bayonet protrusion 165BD (FIG. 3), which will be described later. The lower surface of the bayonet groove BM is formed flush with the upper surface of the side portion 165AB. Further, the upper surfaces of the groove forming portions 165AC are the first upper surface TP1 which is the surface on the side where the bayonet protrusion 165BD enters the bayonet groove BM, and the surface opposite to the side where the bayonet protrusion 165BD enters the bayonet groove BM. It is provided with a second upper surface TP2 that descends from the first upper surface TP1 and is connected to the upper surface of the side portion 165AB.

The case body 165A is made of synthetic resin, and a part of the positive electrode terminal 165D and a part of the negative electrode terminal 165E are embedded to be integrally formed with the positive electrode terminal 165D and the negative electrode terminal 165E. The case body 165A is formed, for example, by insert molding into which the positive electrode terminal 165D and the negative electrode terminal 165E are inserted. In order to prevent a short circuit or the like, it is preferable to cover unnecessary portions of each of the positive electrode terminal 165D and the negative electrode terminal 165E with an insulator.

The lid 165B is a bayonet type lid, and can be attached to and detached from the case body 165A by rotating. The lid 165B includes a covering portion 165BA, a side portion 165BB, three protrusions 165BC, and three bayonet protrusions 165BD.

The covering portion 165BA has a disk shape and covers the accommodating space S of the case body 165A from above. The side portion 165BB projects downward from the covering portion 165BA, has a cylindrical shape surrounding the covering portion 165BA, faces the side portion 165AB of the case body 165A, and covers the side portion 165AB from the outside. The cover portion 165BA and the side portion 165BB constitute a lid main body, and the lid main body has a circular cup shape as a whole and covers the case main body 165A.

Each of the three protrusions 165BC is orthogonal to the outside (direction orthogonal to the rotation axis of the lid 165B (two-dot chain line passing through the center of the lid 165B in FIG. 2) from the outer peripheral surface of the side portion 165BB. It can be said that it is in the radial direction of 165B). The three protrusions 165BC are arranged on the outer peripheral surface of the side portion 165BB at equal intervals of 120 degrees. The protrusion 165BC is formed in such a shape that the user's finger is caught when the lid 165B is rotated to attach or remove the lid 165B. The protrusion 165BC has a chevron shape so as to fit the user's finger.

The three bayonet protrusions 165BD project inward from the inner peripheral surface of the side portion 165BB. The bayonet protrusion 165BD enters the bayonet groove BM of the case body 165A. As a result, both are engaged and the lid 165B is attached to the case body 165A.

As shown in FIG. 5, the O-ring 165C is sandwiched between the side portion 165AB of the case body 165A and the side portion 165BB of the lid 165B. The O-ring 165C is arranged at a position overlapping the button type battery 200 housed in the storage space S in the height direction (vertical direction) of the side portion 165AB of the case body 165A. Specifically, the O-ring 165C is arranged within the range of the thickness H of the button-type battery 200 housed in the storage space S (FIG. 5). The O-ring 165C is a sealing member that prevents a liquid such as water (including seawater) from entering the case body 165A. The height direction of the side portion 165AB of the case body 165A is the rotation axis direction of the lid 165B, the central axis direction of the side portion 165AB, the height direction of the side portion 165BB, and the thickness of the case body 165A (or the button type battery 200). It is also the direction.

The positive electrode terminal 165D contacts the positive electrode of the button type battery 200. The negative electrode terminal 165E contacts the negative electrode of the button type battery 200. One of the positive electrode terminal 165D and the negative electrode terminal 165E is directly connected to the control board 173 via the sensor board 166, and the other is directly connected to the control board 173 by wiring (not shown). As a result, the power supply to the sensor board 166 is controlled by the control board 173.

The mark 168 is a triangle and is formed by printing or the like on a member around the lid 165B attached to the case body 165A. The mark 168 is arranged at a position where one of the three protrusions 165BC comes to the position of the mark 168 when the lid 165B is attached to the case body 165A.

(Attachment / removal of battery case lid)
Next, the operation when the user attaches and removes the lid 165B to the case main body 165A will be described.

When attaching the lid 165B to the case body 165A, the user first lightly grasps the lid 165B and puts it on the case body 165A. Next, the user hooks his finger on the protrusion 165BC from the right side when viewed from above (for example, hooks his thumb on one of the three protrusions 165BC and hooks his index finger on the other one. , Hook the middle finger on the last one.), Rotate the lid 165B counterclockwise. When the user rotates the lid 165B to some extent, the bayonet protrusion 165BD enters the bayonet groove BM of the groove forming portion 165AC and eventually reaches the end of the bayonet groove BM. At this time, since the bayonet protrusion 165BD is engaged with the bayonet groove BM, the lid 165B is attached to the case body 165A. Further, at this time, one of the protrusions 165BC is located at a position corresponding to the mark 168. That is, the user may rotate the lid 165B with the mark 168 as a guide. In this way, the mark 168 can notify the rotation position of the lid 165B (whether the rotation position of the lid 165B is the position attached to the case body 165A, etc.) with reference to the relative position with the bayonet protrusion 165BD.

When the lid 165B is put on the case body 165A, the bayonet protrusion 165BD may hit the upper surface of the groove forming portion 165AC, but even in this case, the user rotates the lid 165B while applying a downward force to rotate the bayonet. The protrusion 165BD can slide on the upper surface of the groove forming portion 165AC, eventually reach the upper surface of the side portion 165AB, and then enter the bayonet groove BM. In this embodiment, the bayonet protrusion 165BD can smoothly reach the upper surface of the side portion 165AB, in particular, by the second upper surface TP2 which is an inclined surface that descends from the first upper surface TP1 and connects to the upper surface of the side portion 165AB. Since the upper surface of the side portion 165AB and the lower surface inside the bayonet groove BM are flush with each other, the bayonet protrusion 165BD can finally reach the bayonet groove BM smoothly.

When removing the lid 165B from the case body 165A, the user first hooks a finger on the protrusion 165BC from the left side when viewed from above, and rotates the lid 165B clockwise. When the user rotates the lid 165B to some extent, the entire portion of the bayonet protrusion 165BD is not engaged with the bayonet groove BM. From this state, the user can remove the lid 165B from the case body 165A by pulling the lid 165B upward.

When the lid 165B is removed from the case body 165A, if the lid 165B is continuously rotated, the bayonet protrusion 165BD climbs the second upper surface TP2 which is an inclined surface, so that the lid 165B can be smoothly removed from the case body 165A.

(Effect of embodiment)
Since the user can rotate the lid 165B by hooking a finger on the protrusion 165BC, the lid 165B can be attached to or removed from the case body 165A without using coins or tools. In this embodiment, instead of providing the lid 165B with a groove (for example, a coin groove) or a recess for inserting a coin or a tool, the lid 165B protrudes outward (in a direction orthogonal to the rotation axis of the lid 165B) from the outer peripheral surface of the side portion 165BB. Since the protruding portion 165BC is provided, the thickness of the lid 165B (the length in the vertical direction in the battery case 165) is suppressed as compared with the case where the groove or the recess is provided. As described above, according to this embodiment, the thickness of the battery case 165 can be suppressed.

Further, the lid 165B has a covering portion 165BA that covers the accommodation space S formed by the bottom portion 165AA of the case body 165A and the tubular side portion 165AB that surrounds the bottom portion 165AA from above, and a tubular shape that covers the side portion 165AB from the outside. Since the side portion 165BB and the protruding portion 165BC have a structure protruding from the side portion 165BB, the user can easily operate the lid 165B. Further, the thickness of the lid 165B is approximately the sum of the thickness of the covering portion 165BA and the height of the side portion 165AB (the length in the vertical direction in the battery case 165). The thickness of the covering portion 165BA can be suppressed, and the thickness of the lid can be suppressed. Therefore, the thickness of the battery case 165 can be suppressed.

Further, in the battery case 165, since the case body 165A and the lid 165B are attached by a bayonet type, the rotation angle required for attaching and detaching the lid 165B is reduced. Therefore, the user can attach and remove the lid 165B more easily than, for example, in the case of the screw type.

Further, even if the bayonet protrusion 165BD hits the upper surface of the groove forming portion 165AC when the lid 165B is put on the case body 165A, as described above, the second upper surface TP2 allows the bayonet protrusion 165BD to smoothly move to the upper surface of the side portion 165AB. Can reach and smoothly enter the bayonet groove BM. Further, when the lid 165B is removed from the case body 165A, if the lid 165B is continuously rotated, the bayonet protrusion 165BD climbs the second upper surface TP2 which is an inclined surface, so that the lid 165B can be smoothly removed. As described above, the battery case 165 has a good operation feeling when the lid 165B is attached or detached.

Further, since the battery case 165 is covered with the cover 162, the waterproofness and design of this portion are improved. Further, the battery case 165 is housed in the dome-shaped cover 162, and when the cover 162 is removed, the battery case 165 protrudes from the surroundings. As a result, the user can easily hook his / her finger on the protrusion 165BC.

By providing the mark 168, the user can compare the protrusion 165BC and the mark 168 and know how far the lid 165B should be rotated.

The side portion 165AB of the case body 165A and the side portion 165BB of the lid 165B are opposed to each other, and the O-ring 165C is sandwiched between the side portion 165AB and the side portion 165BB of the lid 165B, and the position of the O-ring 165C is set to the case body. By arranging the side portion 165AB of the 165A at a position overlapping the button type battery 200 in the height direction, the thickness of the entire battery case 165 can be suppressed. If the O-ring 165C and the button-type battery 200 do not overlap in the height direction, the entire battery case 165 becomes thicker by that amount. However, by overlapping the O-ring 165C and the button-type battery 200, O The entire battery case 165 can be made thinner than when the ring 165C and the button type battery 200 do not overlap.

Further, due to the structure in which the side portion 165BB of the lid 165B covers the side portion 165AB of the case body 165A from the outside, for example, even if the O-ring 165C deteriorates and liquid enters between the side portion 165BB and the side portion 165AB. The liquid does not reach the storage space of the case body 165A unless it reaches the upper end between the side portion 165BB and the side portion 165AB, so that it is difficult for the liquid to enter the storage space S.

Since a part of the positive electrode terminal 165D and a part of the negative electrode terminal 165E are embedded in the case body 165A, it is necessary to provide a substrate for the positive electrode terminal 165D and the negative electrode terminal 165E (a substrate on which each terminal is mounted) in the case body 165A. It disappears. With such a configuration, the thickness of the battery case 165 can be suppressed by the amount of the substrate for the positive electrode terminal 165D and the negative electrode terminal 165E. It should be noted that such a structure is a structure that is easy to adopt when the case main body 165A and the sensor substrate accommodating portion 169 are integrally formed as in this embodiment (positive electrode terminal 165D or negative electrode). This is because the wiring from the terminal 165E can be easily routed to the sensor board 166).

(Modification example)
The present invention is not limited to the above-described embodiment, and various other modifications are possible. For example, the shape and the like of each of the above members can be arbitrarily changed. Further, the present invention can be applied to a spinning reel or the like as long as it is equipped with a battery.

As long as the O-ring 165C and the button type battery 200 overlap in the height direction of the side portion 165AB of the case body 165A, the overlapping mode does not matter. Both may partially overlap.

The number of protrusions 165BC of the lid 165B is arbitrary. Further, the shape of the protruding portion 165BC may be any shape as long as the user's finger can be caught. The protrusion 165BC may be used only for attaching and detaching the lid 165B to the case body 165A (the shape may be changed for that purpose). Both a protrusion 165BC for attachment and a protrusion 165BC for removal may be provided.

The battery case 165 may be arranged at the connecting portion 170. The battery case 165 may accommodate other batteries such as AA batteries. The battery housed in the battery case 165 may be used as a power source for a motor for rotating the spool, for example, other than the water depth counter.

The lid 165B of the battery case 165 may be screwed and attached to the case body 165A. The structure may be such that the side portion 165AB of the case body 165A covers the side portion 165BB of the lid 165B from the outside.

The surface of the lid 165B may be exposed from the cover 162. In this case, the protrusion 165BC may not be provided, and a coin groove may be provided on the surface of the lid 165B as in the conventional case, or a plurality of recesses for engaging the dedicated tool may be provided.
