Description

The present invention relates to an electric fishing reel.

Conventionally, as one type of fishing reel, an electric fishing reel (hereinafter sometimes simply referred to as an electric reel), which can wind a fishing line by rotating a spool using the rotational driving force of a motor, has been known. It is being In general, this type of electric reel can be broadly divided into types in which the motor is placed within the internal space of the spool, and types in which the motor is placed in front of the spool (in the fishing line payout direction). many.

In either type, the motor is housed in a motor housing formed in the reel body, and is held within the motor housing by a lid-like motor holder that closes the opening of the motor housing. Ru. At this time, the motor holder is likely to receive a thrust load from the motor and a radial load due to rotational torque, so it is necessary to firmly fix it to the reel body. Conventionally, a motor holder is often screwed to a reel body using fastening members such as screws and bolts (see, for example, Patent Document 1).

Japanese Patent Application Publication No. 2008-200025

However, when the motor holder is screwed to the reel body, for example, it is necessary to provide a flange piece with a screw insertion hole formed on the motor holder side, and the flange piece is assembled on the reel body side, and the screw It is necessary to provide a screw receiving part with a hole formed therein. In particular, it is necessary to provide the flange piece and the screw receiving part so as to be located radially outward from the opening of the motor accommodating part, which tends to increase the size of the motor holder itself, and the reel body It is also easy to increase the size of. In particular, when the motor is disposed in front of the spool, the size of the motor holder etc. tends to increase in size.

For this reason, it is difficult to further reduce the size of the electric reel, and there is room for improvement. Furthermore, since fastening members such as screws and bolts are required to fix the motor holder to the reel body, the number of parts increases, making it difficult to reduce costs and improve maintainability.

The present invention has been made in consideration of such circumstances, and its purpose is to provide an electric fishing reel that can be downsized and have a reduced number of parts.

(1) The electric fishing reel according to the present invention includes a reel body having a rotatable spool, a motor disposed in a motor housing tube provided in the reel body and rotating the spool, and a motor that rotates the spool. a motor holder that is combined with the reel body so as to close the housing tube and fixes the motor to the reel body; The motor holder includes a main body frame having a side wall frame with an opening formed therein, and a side cover combined with the main body frame so as to cover the side wall frame, and the motor holder includes a lid body that closes the opening of the motor housing cylinder. The periphery of the motor housing cylinder is formed to protrude from the lid body toward the outside in the radial direction of the motor housing cylinder, and the engaged portion formed on the side wall frame or the side cover is an engaging portion that can be engaged in a direction, and the motor holder is sandwiched between the side wall frame and the side cover, thereby restricting movement of the motor in the motor axis direction. It is characterized by

According to the electric fishing reel according to the present invention, during assembly, the motor holder is assembled to the side wall frame so as to close the opening of the motor housing cylinder with the lid, and then the side cover is attached to the main body frame so as to cover the side wall frame. Combine with. Thereby, the motor holder can be sandwiched between the side wall frame and the side cover, and movement in the axial direction of the motor can be restricted. That is, by sandwiching the motor holder between the side wall frame and the side cover, the opening of the motor housing cylinder can be closed with the motor holder while restricting movement of the motor holder in the motor axis direction.
As a result, when the motor disposed in the motor housing cylinder is driven, the thrust load caused by the drive is transmitted from the motor to the motor holder, and the movement of the motor holder in the motor axial direction is restricted, so the thrust It can bear the load.

Furthermore, the motor holder is not only sandwiched between the side wall frame and the side cover, but also engages with the engaged portion formed on the side wall frame or the side cover on the radially outer side of the motor housing tube. The engaging portion engages in the circumferential direction of the motor housing cylinder. Therefore, the motor holder is restrained from moving in the circumferential direction, that is, from rotating around the motor axis. Thereby, even if a radial load around the motor axis due to rotational torque is transmitted from the motor to the motor holder when the motor is driven, the radial load can be received.

From the above, the motor holder can be used to block the opening of the motor accommodating cylinder while appropriately receiving the thrust load and radial load from the motor, thereby stabilizing the motor placed inside the motor accommodating cylinder. It is possible to fix the
In particular, since there is no need to use fastening members such as screws and bolts when assembling the motor holder to the reel body, a large number of parts necessary for these fastenings can be omitted. Therefore, the number of parts can be reduced, leading to lower costs and improved maintainability of the entire electric fishing reel. Furthermore, since there is no need to provide space for fastening members or members such as flange pieces for fastening, it is easy to design the motor holder compactly, which can lead to downsizing of the entire electric fishing reel. can.

(2) A plurality of the engaged parts may be formed at intervals in the circumferential direction, and the engaging part may engage at least one of the engaged parts in the circumferential direction.

In this case, since a plurality of engaged parts are formed, when assembling the motor holder to the side wall frame, the engaging part engages with the engaged part selected depending on the assembly situation, etc. You can assemble it so that it fits. Therefore, it becomes easier to assemble, and it is possible to improve assembly efficiency.

(3) The engaging portions are formed in plurality at intervals in the circumferential direction in correspondence with the plurality of engaged portions, and are engaged in the circumferential direction with respect to each of the plurality of engaged portions. May be combined.

In this case, since the motor holder can be assembled while engaging the engaged portion and the engaging portion at multiple locations, the radial load transmitted from the motor to the motor holder can be received at multiple locations. Therefore, the attitude of the motor holder can be made more stable, and the motor can be more stably fixed. Furthermore, since the radial load is received at a plurality of locations, it is possible to reduce the load applied to each engagement portion between the engaged portion and the engaging portion. Therefore, it is possible to stably combine the motor holders over a long period of time, which can lead to improved product reliability.

(4) The engaged portion may be formed on the side wall frame, and the side cover may be provided with a restricting member that restricts movement of at least one of the engaging portions in the motor axial direction between the side wall frame and the side cover.

In this case, when the motor holder is combined with the side wall frame, the engaging portion can be engaged in the circumferential direction with the engaged portion formed on the side wall frame. Thereby, the motor holder can be assembled while suppressing movement such as rotation around the motor axis. In particular, since the engaged portion is formed on the side wall frame that constitutes the main body frame, the radial load transmitted from the motor to the motor holder can be transferred to the main body frame, which has high rigidity, and the posture of the motor holder is easier to stabilize.
Furthermore, by combining the side cover with the main body frame so as to cover the side wall frame, the engaging part itself can be moved in the motor axis direction using the regulating member while the motor holder is sandwiched between the side wall frame and the side cover. can be regulated. Therefore, it becomes possible to simultaneously and efficiently receive the thrust load and radial load transmitted to the motor holder via the engaging portion.

According to the present invention, it is possible to provide an electric fishing reel that can be downsized and have a reduced number of parts.

In this embodiment, the handle axis O1 and the spool axis O2 are arranged parallel to each other, and the direction along these axes is defined as the left-right direction L1. Further, a direction perpendicular to the left-right direction L1 and along the direction in which the fishing line wound around the spool 4 is let out is defined as a front-back direction L2.
Furthermore, the direction in which the fishing line is let out from the spool 4 in the front-rear direction L2 is defined as the front, and the opposite direction is defined as the rear, and left and right are defined from the viewpoint of the electric reel 1 viewed from the rear side (fisherman's side). Therefore, for example, FIG. 1 is a perspective view of the electric reel 1 viewed diagonally from above and from the left rear.

(Reel body)
As shown in FIGS. 1 to 4, the reel body 2 includes a body frame 10, side covers 20 that cover both left and right sides of the body frame 10, and a front cover 30 that covers the front side of the body frame 10. .

The main body frame 10 is a molded part made of, for example, synthetic resin or metal (for example, aluminum die-casting). The main body frame 10 includes a first side wall 11 and a second side wall 12 that are arranged to face each other in the left-right direction L1 with the spool 4 in between, and a connecting member that connects the first side wall 11 and the second side wall 12 to each other in the left-right direction L1. It is equipped with 13.

The first side wall (side wall frame according to the present invention) 11 is a left side wall disposed on the left side (LH) with respect to the spool 4. On the other hand, the second side wall 12 is a right side wall disposed on the right side (RH) with respect to the spool 4. Note that the handle 3 is arranged further to the right (RH) than the second side wall 12 and is attached to the main body frame 10 using the second side wall 12.
Therefore, the electric reel 1 of this embodiment is a right-side handle type reel. Note that the second side wall 12 is formed to protrude more downward than the first side wall 11 because a connector portion 23 and the like, which will be described later, are provided therein.

The connecting member 13 is formed in a plate shape that connects the first side wall 11 and the second side wall 12 in the left-right direction L1, and is disposed near the bottom of the first side wall 11. Thereby, the first side wall 11 and the second side wall 12 are firmly connected via the connecting member 13.
In addition, a mounting leg piece 14 for mounting the electric reel 1 on a fishing rod is formed in a central portion of the connecting member 13 in the left-right direction L1 so as to extend along the front-rear direction L2.

In the main body frame 10 configured as described above, at least the motor housing tube 7 that houses the motor 8 inside, the spool 4, and the clutch operating lever 5 are arranged between the first side wall 11 and the second side wall 12.

The spool 4 is arranged between the first side wall 11 and the second side wall 12 so as to be located on the rear side of the handle axis O1. The motor housing cylinder 7 is arranged between the first side wall 11 and the second side wall 12 so as to be located on the front side of the handle axis O1. Therefore, the electric reel 1 of this embodiment is of a so-called spool-out motor type in which the motor 8 is disposed further forward than the spool 4.
Note that the motor housing cylinder 7 is arranged between the first side wall 11 and the second side wall 12 so that an opening 62 is formed in the first side wall 11.

The side cover 20 includes a first side cover (side cover according to the present invention) 21 that is combined with the main body frame 10 so as to cover the first side wall 11 in which the opening of the motor housing tube 7 is formed from the left side (LH). , a second side cover 22 combined with the main body frame 10 so as to cover the second side wall 12 from the right side (RH).

The first side cover 21 is formed to bulge toward the left side (LH), and is fixed to the first side wall 11 with screws, for example. Thereby, a predetermined accommodation space is formed between the first side cover 21 and the first side wall 11. Note that the first side cover 21 will be explained in detail later.

The second side cover 22 is formed to bulge toward the right side (RH), and is fixed to the second side wall 12 by screws, for example. Thereby, a predetermined accommodation space is formed between the second side cover 22 and the second side wall 12.
A connector section 23 for connecting a power reel cord for supplying power from an external power source or a portable battery is provided at the lower front part of the second side cover 22 with its connecting end (not shown) facing downward. It is installed in the same position. Note that each drawing shows a state in which the connection end is protected by the protective cap 24.

The front cover 30 is combined with the main body frame 10 so as to cover the front part of the main body frame 10 from the front. Specifically, the front cover 30 is combined with the front portions of the first side wall 11 and the second side wall 12 so as to cover the motor housing cylinder 7 from the front, and is attached to the first side wall 11 and the second side wall 12, for example. It is screwed on. Note that the front cover 30 is attached so as not to block a movement area of a level wind 55, which will be described later.

(Counter case)
A counter case 40 is provided on the top of the main body frame 10 configured as described above. The counter case 40 is disposed between the first side wall 11 and the second side wall 12 and is fixed to the upper part of the first side wall 11 and the upper part of the second side wall 12 by, for example, screws.

The counter case 40 includes a thin case main body 41 that is longer in the front-rear direction L2 than the left-right direction L1, a display section 42 provided in the case main body 41, and a motor control section (not shown) provided in the case main body 41. The Lord is preparing.
The display unit 42 is formed of, for example, a liquid crystal display, and is exposed on the upper surface of the case body 41 while being protected by a glass cover or the like. The motor control section is composed of, for example, a microcomputer equipped with a CPU, etc., and controls the motor 8 as well as display control for displaying various information on the display section 42.

The motor control unit receives, for example, control signals from a plurality of (three in the illustrated example) operation buttons 43 provided on the top surface of the case body 41, and control signals from an operation switch 44 provided on the top surface of the case body 41. Furthermore, control signals from a spool sensor (for example, a sensor that detects the rotational speed, rotational direction, etc. of the spool 4), which is not shown, are input.

As a result, the motor control section can display various information such as the time for throwing the tackle, the water depth of the tackle, the hoisting speed or the hoisting torque of the motor 8 on the display section 42 based on various control signals; It is possible to control the rotation of the motor 8 according to the operation of the operation switch 44 and adjust the hoisting speed, hoisting acceleration, etc. as desired.
Therefore, anglers can perform manual winding operations by operating the handle and automatic winding operations using the operation switch 44.

(handle)
The handle 3 is arranged on the right side (RH) of the main body frame 10 and the first side cover 21. The handle 3 includes a handle shaft portion 50 arranged rotatably around the handle axis O1, a handle arm 51 non-rotatably mounted on the handle shaft portion 50, and a handle arm 51 mounted at the end of the handle arm 51 parallel to the handle axis O1. The handle knob 52 is rotatably mounted around an axis.
A drag 53 (star drag) disposed coaxially with the handle axis O1 is provided between the handle arm 51 and the first side cover 21. The drag 53 brakes the rotation of the spool 4 by applying an arbitrary drag force to the spool 4 when winding the fishing line, thereby contributing to suppressing the breakage of the fishing line.

Rotational torque from the handle 3 configured in this manner is directly transmitted to the spool 4 via a rotation transmission mechanism (not shown) when the clutch mechanism 6 is in a clutch-on state.
In this embodiment, a so-called single handle type in which a handle knob 52 is attached to one end of a handle arm 51 is described as an example, but the present invention is not limited to this case. For example, the electric reel 1 may be of a so-called double handle type, in which the handle knobs 52 are attached to both ends of the handle arm 51, and the center portion of the handle arm 51 is attached to the handle shaft portion 50 in a non-rotatable manner.

(spool)
The spool 4 is disposed between a first side wall 11 and a second side wall 12 in the frame body, and rotates around the spool axis O2 via bearings (not shown) on each of the first side wall 11 and the second side wall 12. Possibly supported.
The spool 4 includes a spool rotating shaft (not shown) that rotates around the spool axis O2, and a bobbin trunk 4a that is arranged coaxially with the spool rotating shaft and rotates in conjunction with the spool rotating shaft. .

(clutch mechanism)
The clutch mechanism 6 can be switched between a clutch-on state in which the rotational torque from the handle 3 can be transmitted to the spool 4 via a rotation transmission mechanism (not shown) and a clutch-off state in which it cannot be transmitted, by operating the clutch operating lever 5. has been done. Therefore, by rotating the handle 3 in the clutch-on state, the rotational torque accompanying the rotation of the handle 3 can be transmitted to the spool 4, and the spool 4 can be rotated around the spool axis O2. ing. This allows manual winding operation.
Note that when the clutch mechanism 6 is in the clutch-off state, the rotational torque accompanying the rotational operation of the handle 3 is not transmitted to the spool 4, and the spool 4 is in a freely rotatable state (spool-free state).

The clutch operating lever 5 is a switching lever for switching the clutch mechanism 6 between a clutch-on state and a clutch-off state. The clutch operation lever 5 is arranged behind the spool 4 between the first side wall 11 and the second side wall 12, and is movable up and down so as to swing around the spool axis O2. .

The rotation transmission mechanism is configured to transmit rotational torque to the spool 4 while increasing the rotation speed of the handle 3. Further, when the clutch mechanism 6 is in the clutch-on state, the rotation transmission mechanism not only transmits the rotational torque caused by the rotation operation of the handle 3 to the spool 4 but also transmits the rotation torque to the spool 4 as well as to a level wind mechanism (not shown) having a level wind 55. configured to communicate.
Note that the level wind 55 is disposed between the motor housing tube 7 and the counter case 40, and is capable of reciprocating in the left-right direction L1 between the first side wall 11 and the second side wall 12 as the spool 4 rotates. (See Figure 3). This makes it possible to evenly wind the fishing line onto the spool 4 without bias.

Further, the rotation transmission mechanism is capable of transmitting the rotational torque accompanying the drive of the motor 8 to the spool 4 when the motor 8 is driven when the clutch mechanism 6 is in the clutch-on state. This allows automatic winding operation. Note that the rotation transmission mechanism transmits rotation torque to the spool 4 while the rotation of the motor 8 is decelerated.

(Motor housing cylinder)
As shown in FIG. 3, the motor housing cylinder 7 is arranged between the first side wall 11 and the second side wall 12 on the front side of the handle axis O1, and is arranged coaxially with the motor axis O3 extending in the left-right direction L1. It is shaped like a capped cylinder.
Specifically, as shown in FIGS. 5 to 8, the motor housing cylinder 7 closes a housing cylinder body 60 formed in a cylindrical shape centered on the motor axis O3 and a right opening 62 of the housing cylinder body 60. It is formed into a cylindrical shape with a bottom and a bottom wall 61 . As a result, the motor housing cylinder 7 has an opening 62 in the first side wall 11, and is open on the left side (LH).

In the illustrated example, the housing cylinder main body 60 and the bottom wall 61 are integrally formed, but the present invention is not limited to this case. For example, the housing cylinder main body 60 and the bottom wall 61 may be formed separately, and the housing cylinder main body 60 and the bottom wall 61 may be combined into one body by screw connection, threading, fitting, or the like.
In the present embodiment, when viewed from the direction of the motor axis O3, the direction intersecting the motor axis O3 is referred to as the radial direction, and the direction rotating around the motor axis O3 is referred to as the circumferential direction.

As shown in FIG. 3, the housing cylinder main body 60 is provided between the front part of the first side wall 11 and the front part of the second side wall 12 so as to be disposed below the level wind 55. ing. Therefore, the motor housing tube 7 is arranged so as to be exposed toward the front. However, the motor housing tube 7 is partially protected from the front side by the front cover 30.
As shown in FIGS. 5 to 8, an enlarged diameter tube 63 having a larger diameter than other portions is formed in a portion of the housing tube main body 60 located on the opening 62 side. Therefore, the motor accommodating cylinder 7 is integrally formed with the first side wall 11 via the enlarged diameter cylinder 63. Further, a cylindrical boss portion 64 that protrudes toward the right side (RH) is formed in the center portion of the bottom wall 61.

Here, the first side wall 11 constituting the main body frame 10 will be explained in detail.
As shown in FIG. 5, the first side wall 11 functions as the left side wall of the main body frame 10, and is normally covered by the first side cover 21. The first side wall 11 is formed longer in the front-rear direction L2 than in the up-down direction, and as described above, the motor housing tube 7 is integrally formed on the front side, and the first side wall 11 is formed to be longer in the front-rear direction L2 than in the up-down direction. The outline is formed concentrically with the motor housing cylinder 7. The rear side of the first side wall 11 is formed into a semicircular shape in side view that swells toward the rear.

Above the first side wall 11, the counter case 40 is arranged as described above. The counter case 40 is screwed to the upper side of the first side wall 11 with fixing screws 70. In the illustrated example, the counter case 40 is fixed by two fixing screws 70 arranged at intervals in the front-rear direction L2.
Various components (for example, bearings, gears, receiving members, etc.) constituting the electric reel 1 are arranged in a portion of the first side wall 11 that is located rearward of the motor housing cylinder 7. Furthermore, an edge 71 that protrudes toward the left side (LH) is continuously formed on the outer peripheral edge of the first connecting wall so as to extend along the outer peripheral edge.

Further, the first side wall 11 is formed with a connecting screw 72, a screw hole 73, and a receiving tube portion 74 for attaching the first side cover 21.
As shown in FIGS. 5 and 6, the connecting screws 72 are arranged so as to be separated from each other in the front-rear direction L2 with the two fixing screws 70 that attach the counter case 40 sandwiched therebetween on the upper side of the first side wall 11. One is formed. These connecting screws 72 are attached from the housing cylinder main body 60 side, so that they protrude toward the left side (LH). Note that the number of connecting screws 72 is not limited to two, and may be changed as appropriate.
The screw hole 73 is formed on the lower side of the first side wall 11 so as to be located at a central portion in the front-rear direction L2. The receiving tube portion 74 is a tube member that is hollow inside and opens toward the left side (LH), and is formed in a portion of the first side wall 11 that is located forward of the screw hole 73.

(motor)
As shown in FIGS. 7 and 9, the motor 8 includes a motor output shaft 80 that rotates around the motor axis O3 and a motor body 81 that rotationally drives the motor output shaft 80, and is housed in the motor housing cylinder 7. There is.

The motor output shaft 80 is arranged coaxially with the motor axis O3 so as to pass through the motor main body 81 in the direction of the motor axis O3. At this time, the motor output shaft 80 is formed to protrude to the left side (LH) from the first side wall 11 and from the boss portion 64 to the right side (RH). Note that in each drawing, the illustration of the motor output shaft 80 is simplified.

The motor output shaft 80 is stably supported by a plurality of bearings including a bearing 83 mounted inside the boss portion 64, for example. An annular motor waterproof seal 84 is attached to the inner side of the boss portion 64 at a portion adjacent to the right side (RH) of the bearing 83. The inner peripheral edge of the motor waterproof seal 84 is in sliding contact with the entire outer peripheral surface of the motor output shaft 80 . This prevents water, dust, etc. from entering the motor housing cylinder 7.

For example, serrations (sawtooth grooves) 85 are formed at the left end of the motor output shaft 80 on the outside (left side (LH)) of the first side wall 11 . A one-way clutch 86 attached to a motor holder 9, which will be described later, is coupled to the serrations 85. As a result, rotation (reverse rotation) of the motor output shaft 80 in the direction in which the fishing line is paid out is restricted. Therefore, the motor 8 is only allowed to rotate in one direction for winding the fishing line. Note that the mounting position of the one-way clutch 86 is not limited to the motor holder 9, and may be changed as appropriate.

The motor body 81 includes a bottomed cylindrical case body 81a that opens on the left side (LH), and an end cap 81b that closes the left side opening of the case body 81a. Connection cables 87 that connect the motor main body 81 and a motor control section disposed in the counter case 40 are inserted through the end cap 81b at intervals in the circumferential direction, for example. In the illustrated example, two connection cables 87 are arranged at equal intervals in the circumferential direction (specifically, they are arranged so as to face each other in the radial direction with the motor axis O3 in between).

Furthermore, the motor main body 81 has a rotor fixed to the motor output shaft 80, which has a coil, for example, and a permanent magnet. The main components are a commutator, a commutator, and a brush.

The motor 8 configured as described above is electrically connected to a motor control section through a connection cable 87 (see FIG. 5), and its driving is controlled by the motor control section.
A space located on the right side (RH) of the bottom wall 61 in the motor housing cylinder 7 is provided with a deceleration mechanism (not shown) that decelerates the rotational torque of the motor output shaft 80 and transmits it to the spool 4, for example. Note that the configuration of the motor 8 may be changed as appropriate; for example, a brushless motor or the like may be employed.

(1st side cover)
The first side cover 21 will be explained in detail.
As shown in FIGS. 1 to 4 and FIG. 10, the first side cover 21 is formed longer in the front-rear direction L2 than in the up-down direction, corresponding to the shape of the first side wall 11, and extends from the left side (LH ) is a cover member that covers from. More specifically, the first side cover 21 covers not only the first side wall 11 but also the motor holder 9 attached so as to close the motor housing cylinder 7, the front cover 30, and a part of the counter case 40 on the left side ( LH) is combined with the main body frame 10 so as to cover it.

The first side cover 21 includes a cover main body 90 formed to swell toward the left side (LH), and a right side (first side wall 11 side) from the outer peripheral edge of the cover main body 90 to the entire circumference of the outer peripheral edge. ) is provided with a peripheral edge portion 91 bent toward.
The peripheral edge 91 of the first side cover 21 can contact the edge 71 of the first side wall 11, the side edge of the front cover 30, and the side surface of the counter case 40 without gaps. Thereby, the first side cover 21 has a structure in which it is difficult for water, dust, etc. to enter the inside thereof. Further, a lower front peripheral edge 91 of the first side cover 21 is formed concentrically with the motor housing cylinder 7 in accordance with the main body frame 10 .

Further, the cover body 90 is formed with a screw receiving cylinder portion 92 and a connecting pin 93 protruding toward the first side wall 11 side, and an insertion hole 95 through which a connecting screw 94 is inserted is formed. .

The connecting pin 93 is arranged so as to face the receiving cylinder portion 74 formed on the first side wall 11 in the left-right direction L1, and is formed to protrude toward the right side (RH). The connecting pin 93 is formed, for example, in a cylindrical shape, and is capable of entering into the receiving cylinder portion 74 formed on the first side wall 11 . The insertion hole 95 is arranged to face the screw hole 73 formed in the first side wall 11 in the left-right direction L1, and is formed to penetrate the cover body 90 in the left-right direction L1.

When assembling the first side cover 21 configured as described above to the main body frame 10, the first side cover 21 is inserted into the receiving cylinder portion 74 formed on the first side wall 11 while inserting the connecting pin 93 into the first side wall 11. and cover it from the left side (LH). At this time, by inserting the connecting pin 93 into the receiving cylinder part 74, the first side cover 21 can be guided so that it is properly combined with the main body frame 10, so that the side cover 21 can be easily and appropriately assembled. A cover 20 can be placed over it. After fitting the first side cover 21 to the main body frame 10, the connection screw 94 is screwed into the screw hole 73 from the left side (LH) of the first side cover 21 through the insertion hole 95, and ), while passing through the main body frame 10, the connecting screw 72 is screwed into the female threaded portion in the screw receiving cylinder portion 92 of the first side cover.

As a result, the peripheral edge 91 of the first side cover 21 is brought into contact with the edge 71 of the first side wall 11, the side edge of the front cover 30, and the side surface of the counter case 40 without gaps, and the first It is possible to screw the side cover 21 to the main body frame 10.
In addition, since the lower front contour of the first side cover 21 is formed approximately concentrically with the motor housing cylinder 7, that is, the motor 8, the outer shape corresponds to the shape of the motor 8, etc. It can be made into a shape without. Therefore, it is possible to improve the appearance and design.

(motor holder)
As shown in FIGS. 5 to 7, FIG. 11, and FIG. 12, the motor holder 9 is assembled to the first side wall 11 of the reel body 2 so as to close the motor housing cylinder 7, and the motor 8 is connected to the reel body 2. It plays a fixed role.
The motor holder 9 includes a capped cylindrical lid 100 that closes the opening 62 of the motor housing cylinder 7, and a cap 100 that protrudes radially outward from the lid 100, and is formed on the first side wall 11. The engagement protrusion (engaging portion according to the present invention) 101 that can be engaged in the circumferential direction with the engaging recessed portion (engaged portion according to the present invention) 120 is provided.

The lid body 100 includes a fitting cylinder 102 that is fitted inside the enlarged diameter cylinder 63 in the motor housing cylinder 7, and a closing wall 103 that closes the left opening of the fitting cylinder 102, and is coaxial with the motor axis O3. It is located in Further, in the central portion of the closing wall 103, a capped cylindrical housing portion 104 protruding toward the left side (LH) is formed so as to be disposed coaxially with the motor axis O3. Thereby, the lid body 100 is formed into a capped cylinder shape in which the central portion of the closing wall 103 partially bulges toward the left side (LH).

An annular groove 105 is formed on the outer circumferential surface of the fitting cylinder 102 and is recessed radially inward over the entire circumference. An O-ring 106 is installed in this annular groove 105 so as to be in close contact with the inner circumferential surface of the diameter-expanding tube 63 (see FIG. 7). As a result, the O-ring 106 can be used to properly seal between the fitting tube 102 and the enlarged diameter tube 63, and water, dust, etc. can be prevented from entering the motor housing tube 7 from the first side wall 11 side. suppressing things.

The annular groove 105 does not have to be formed on the outer circumferential surface of the fitting tube 102, but may be formed on the inner circumferential surface of the expanding tube 63, for example. Even in this case, it is possible to appropriately seal between the fitting tube 102 and the expanding tube 63 using the O-ring 106.

Note that the fitting tube 102 is not entirely placed inside the expanded diameter tube 63, but a part of it is placed outside (left side (LH)) of the expanded diameter tube 63, and is a large diameter tube with a slightly expanded diameter. The diameter cylinder 107 is used. The outer peripheral edge of the closing wall 103 is connected to the large diameter cylinder 107. The large diameter cylinder 107 is in contact with the first side wall 11 from the left side (LH). This allows the fitting tube 102 to be appropriately fitted into the expanded diameter tube 63.

Through holes 108 are formed in the blocking wall 103 to pass through the connection cables 87 that connect the motor 8 and the motor control unit. In the illustrated example, four through holes 108 are formed at equal intervals in the circumferential direction, and two of the through holes 108 are each inserted with two connection cables 87 that pass through the end cap 81b. This makes it possible to wire the connection cables 87 between the motor 8 and the motor control unit.

Incidentally, motor fixing screws 109 that are screwed into screw holes 109a (see FIG. 9) formed in the end cap 81b are attached to the remaining two through holes 108. Thereby, the motor main body 81 is fixed to the motor holder 9.
Therefore, for example, after the motor holder 9 and the motor main body 81 are fixed to each other, the motor main body 81 can be accommodated in the motor housing cylinder 7. Note that FIG. 9 shows a state in which the motor holder 9 has been intentionally removed from the state shown in FIG.

The one-way clutch 86 described above is attached to the inside of the housing tube 104, and the left end portion of the motor output shaft 80 is housed therein.

The engagement protrusion 101 is formed to protrude radially outward from the outer peripheral surface of the large diameter cylinder 107. In this embodiment, two engaging protrusions 101 are formed at equal intervals in the circumferential direction. That is, the engagement protrusion 101 is composed of a first engagement protrusion 111 and a second engagement protrusion 112. Thereby, the first engagement protrusion 111 and the second engagement protrusion 112 are arranged to face each other in the radial direction with the motor axis O3 in between.
The first engagement protrusion 111 and the second engagement protrusion 112 are capable of engaging with an engagement recess 120 formed in the first side wall 11 in the circumferential direction, respectively.

The engagement recess 120 will be explained.
As shown in FIGS. 6, 7, and 9, a portion of the edge 71 of the first side wall 11 that is located forward of the motor holder 9 has a first engagement recessed toward the right side (RH). A recess 121 is formed. The first engagement protrusion 111 is fitted into the first engagement recess 121 from the left side (LH) and engaged in the circumferential direction.

Furthermore, an engagement plug 125 is fixed to a portion of the first side wall 11 located on the opposite side of the first engagement recess 121 in the radial direction across the motor axis O3. The engagement plug 125 may be formed integrally with the first side wall 11 or may be formed separately and combined with the first side wall 11.
The engagement plug 125 includes a base end portion 127 positioned on the first side wall 11 by a positioning pin 126, and an engagement claw portion 128 formed in a bifurcated shape. The inner side of the engaging claw portion 128 is a second engaging recess 122 that opens toward the motor holder 9 side. The second engagement protrusion 112 is fitted into the second engagement recess 122 from the left side (LH), thereby being engaged in the circumferential direction. Note that a screw hole 129 is formed in the base end portion 127.

As described above, the two engagement recesses 120 (i.e., the first engagement recess 121 and the second engagement recess 122) are formed at intervals in the circumferential direction, and the two engagement protrusions 101 (i.e., The first engagement protrusion 111 and the second engagement protrusion 112 are configured to engage with the engagement recess 120 in the circumferential direction, respectively.

The motor holder 9 configured as described above is sandwiched between the first side wall 11 and the first side cover 21, as shown in FIG. 13, so that movement in the direction of the motor axis O3 is restricted. It is configured. Specifically, the first side cover 21 prevents the movement of the motor holder 9 toward the motor axis O3 by pressing the first engagement protrusion 111 from the left side (LH) between the first side cover 21 and the first side wall 11. A regulating protrusion (regulating member according to the present invention) 130 is provided.

As shown in FIG. 10, the regulating protrusion 130 is formed to protrude from the inside of the peripheral edge 91 of the first side cover 21 toward the first engagement protrusion 111, and the first side cover 21 is attached to the main body frame. 10 (see FIG. 13), the first engagement protrusion 111 is pressed from the left side (LH). Thereby, the first engagement protrusion 111 can be prevented from coming out from the first engagement recess 121 using the regulating protrusion 130, and the entire motor holder 9 can be connected to the first side wall 11 and the first side. By sandwiching it between the cover 21 and the cover 21, it is possible to restrict movement in the direction of the motor axis O3.

Further, in this embodiment, as shown in FIGS. 5 to 7, a regulating screw 135 is provided which is screwed into a screw hole 129 formed in the base end 127 of the engagement plug 125, and the regulating screw 135 is used to The second engagement protrusion 112 is pressed down from the left side (LH). That is, among the engaging protrusions 101, the engaging protrusions 101 (first engaging protrusions 111) whose movement in the direction of the motor axis O3 is regulated by the regulating protrusions 130 are different from the engaging protrusions 101 ( It is possible to restrict the movement of the second engagement protrusion 112) in the direction of the motor axis O3 using the restriction screw 135.
Specifically, the head of the regulating screw 135 is used to regulate the movement of the second engaging protrusion 112 in the direction of the motor axis O3.

(Effect of electric reel)
Next, a case will be described in which the electric reel 1 configured as described above is used.
In this electric reel 1, a power reel cord electrically connected to an external power source or a portable battery is electrically connected to the connector portion 23. Thereby, electric power can be supplied to the motor 8, and the motor 8 can be driven.

Then, by operating the clutch operation lever 5 and putting the clutch mechanism 6 in the clutch-off state, the spool 4 can be freely rotated, and the fishing line can be let out and the tackle can be thrown into the water. Thereafter, by operating the clutch operating lever 5, the clutch mechanism 6 is switched to the clutch-on state, and, for example, by rotating the handle 3, the spool 4 can be rotated to manually wind the fishing line. Alternatively, the fishing line can be automatically wound by driving the motor 8 and rotating the spool 4 by operating the operation switch 44.
Thereby, the electric reel 1 can be used for fishing.

By the way, according to the electric reel 1 of this embodiment, at the time of assembly, after the motor holder 9 is assembled to the first side wall 11 so as to close the opening 62 of the motor housing cylinder 7 with the lid body 100, the motor holder 9 is assembled to the first side wall 11, and then the electric reel 1 shown in FIGS. As shown in the figure, the first side cover 21 is assembled to the main body frame 10 so as to cover the first side wall 11.
As a result, while the motor holder 9 is sandwiched between the first side wall 11 and the first side cover 21, as shown in FIG. ), and the movement of the motor holder 9 in the direction of the motor axis O3 can be restricted. Thereby, the opening 62 of the motor housing cylinder 7 can be closed with the motor holder 9 while restricting the movement of the motor holder 9 in the direction of the motor axis O3.

Therefore, when the motor 8 disposed in the motor housing cylinder 7 is driven, if a thrust load due to the drive is transmitted from the motor 8 to the motor holder 9, movement of the motor holder 9 in the direction of the motor axis O3 is restricted. This allows it to absorb thrust loads.

Moreover, as shown in FIGS. 6 and 7, the motor holder 9 engages with the engagement recess 120 (i.e., the first engagement recess 121 and the second engagement recess 122) formed in the first side wall 11. The protruding pieces 101 (ie, the first engaging protruding piece 111 and the second engaging protruding piece 112) are engaged with each other in the circumferential direction. Therefore, the motor holder 9 is restrained from moving in the circumferential direction, that is, from rotating around the motor axis O3. Thereby, even if a radial load around the motor axis O3 caused by rotational torque is transmitted from the motor 8 to the motor holder 9 when the motor 8 is driven, the radial load can be received.

From the above, the motor holder 9 can be used to block the opening 62 of the motor accommodating cylinder 7 while appropriately receiving the thrust load and radial load from the motor 8. It becomes possible to stably fix the motor 8.

In particular, since there is no need to use fastening members such as screws and bolts when assembling the motor holder 9 to the reel body 2, a large number of parts necessary for these fastenings can be omitted. Therefore, the number of parts can be reduced, leading to lower costs and improved maintainability of the electric reel 1 as a whole. Furthermore, since there is no need to provide a space for a fastening member or a member such as a flange piece for fastening, it is easy to design the motor holder 9 compactly, which can lead to downsizing of the electric reel 1 as a whole. .
In particular, when the motor 9 is disposed at the lower front side of the reel body 10, the peripheral edge 91 at the lower front side of the first side cover 21 is concentric with the motor housing tube 7, as described above. Since it is formed, it is possible to eliminate unnecessary molded parts, and the appearance and design can be improved.

Therefore, according to the electric reel 1 of this embodiment, it is possible to achieve miniaturization and a reduction in the number of parts, and it can be used as an easy-to-use electric reel 1.

Furthermore, the motor holder 9 can be combined by the engagement between the first engagement recess 121 and the first engagement protrusion 111 and the engagement between the second engagement recess 122 and the second engagement protrusion 112. Therefore, the radial load transmitted from the motor 8 to the motor holder 9 can be received at multiple locations (two locations). Therefore, the posture of the motor holder 9 can be made more stable, and the motor 8 can be fixed more stably. Furthermore, since the radial load is received at a plurality of locations (two locations), it is possible to reduce the load burden on each engagement portion. Therefore, it becomes possible to stably combine the motor holders 9 over a long period of time, which can lead to improved product reliability.

Further, when the motor holder 9 is combined with the first side wall 11, the first engagement protrusion 111 and the second engagement recess 121 and the second engagement recess 122 formed in the first side wall 11 are connected to each other. The engagement protrusion 112 can be engaged in the circumferential direction. Thereby, the motor holder 9 can be assembled in a state where movement such as rotation around the motor axis O3 is suppressed.
In particular, since the first engaging recess 121 and the second engaging recess 122 are formed in the first side wall 11 constituting the main body frame 10, the radial load transmitted from the motor 8 to the motor holder 9 can be absorbed with high rigidity. It becomes possible to receive the motor into the main body frame 10, and the posture of the motor holder 9 can be more easily stabilized.

Furthermore, since the movement of the first engagement protrusion 111 itself in the direction of the motor axis O3 can be restricted using the regulating protrusion 130, the movement of the first engagement protrusion 111 itself in the direction of the motor axis O3 can be restricted, so that the movement of the first engagement protrusion 111 itself in the direction of the motor axis O3 can be restricted. It becomes possible to efficiently receive thrust loads and radial loads at the same time.
In addition, since the movement of the second engaging protrusion 112 itself in the direction of the motor axis O3 can be restricted using the regulating screw 135, the movement of the second engaging protrusion 112 itself in the direction of the motor axis O3 can be restricted, so that the movement of the second engaging protrusion 112 itself in the direction of the motor axis O3 can be restricted. It is also possible to efficiently receive thrust loads and radial loads at the same time.

Although the embodiments of the present invention have been described above, these embodiments are presented as examples and are not intended to limit the scope of the invention. The embodiments can be implemented in various other forms, and various omissions, substitutions, and changes can be made without departing from the gist of the invention. The embodiments and their modifications include, for example, those that can be easily imagined by those skilled in the art, those that are substantially the same, and those that are equivalent.

For example, in the above embodiment, a spool-out motor type in which the motor housing tube 7 is arranged in front of the spool 4 has been described as an example, but the invention is not limited to this case. It is also possible to use a spool-in motor type provided with a housing cylinder 7.

Further, in the above embodiment, a right handle type is used and the motor housing tube 7 is opened toward the first side wall 11 side. may be configured to open on the second side wall 12 side. Even in this case, similar effects can be achieved.

Further, in the above embodiment, the case where two each of the engagement recesses 120 and the engagement protrusions 101 are formed has been described as an example, but the invention is not limited to this case. For example, the engagement recesses 120 and the engagement protrusions 101 are One engaging protrusion 101 may be formed, or three or more engaging protrusions 101 may be formed.
Furthermore, the number of engagement recesses 120 and the number of engagement protrusions 101 do not need to be the same; for example, one engagement protrusion 101 is formed, whereas two or more engagement recesses 120 are formed. I don't mind if you do. In this case, when assembling the motor holder 9 to the first side wall 11, assembly can be performed such that the engaging protrusion 101 engages with the engaging recess 120 selected depending on the assembly situation, for example. . Therefore, it becomes easier to assemble, and it is possible to improve assembly efficiency.

Further, in the above embodiment, the case where the engagement recess 120 is formed on the first side wall 11 has been described as an example, but the invention is not limited to this case, and the engagement recess 120 may be formed on the first side cover 21 side. I do not care. Even in this case, when the first side cover 21 is combined with the main body frame 10, the engagement recess 120 and the engagement protrusion 101 can be engaged in the circumferential direction, so the same effect can be achieved. It can be effective.
However, by forming the engagement recess 120 in the first side wall 11 as in the above embodiment, the engagement recess 120 and the engagement protrusion 101 can be properly connected to each other before the first side cover 21 is assembled. This is more preferable because it allows you to know that they are engaged in the circumferential direction.

Further, in the above embodiment, the movement of the motor holder 9 in the direction of the motor axis O3 is restricted by using the restriction protrusion 130, but the invention is not limited to this case. For example, the first side cover 21 itself The motor holder 9 may be sandwiched between the first side wall 11 and the movement of the motor holder 9 in the direction of the motor axis O3 may be restricted.
