If the flange portion 45 is fixed to the support plate 17 with screws 49, the container 15 is attached to the support plate 17 integrally. An elastic seal member 53 such as an O-ring is interposed in the recess 51 provided on the outer periphery of the engagement protrusion 47, and the elastic seal member 53 serves as a joint portion between the container 15 and the support plate 17. Water tightness is achieved.
[0016]
Furthermore, an annular elastic seal member 57 is interposed between the end surface 55 of the motor 35 on the left motor shaft 37 side and the tip of the bearing support portion 39 described above, and on the inner periphery of the bearing support portion 39. A cylindrical elastic seal member 58 is interposed between the one-way clutch 41. An electric line 61 connected to the electric contact 59 of the motor 35 is wired through the support plate 17. An elastic seal member 63 is also interposed between the electric line 61 and the support plate 17. Watertightness is ensured.
[0017]
In FIG. 2, reference numeral 65 denotes a rotation-preventing mechanism that prevents the motor 35 accommodated in the container 15 from rotating. The rotation-preventing mechanism 65 includes a support 67 that extends in the axial direction from the support plate 17, and the support 67 is configured by a recess 69 formed on the end surface 55 of the motor 35 so as to be engageable.
On the other hand, as shown in FIG. 2, the other end of the container 15 located on the side opposite to the side frame 5 is opened as it is, and the right motor shaft 71 of the motor 35 projects from the opening 69 toward the side plate 11. However, the other end side is provided with a reduced diameter portion 77 bent inward.
[0018]
A cap 75 formed of a hard material along the shape of the end surface 73 of the motor 35 is attached to the reduced diameter portion 77 so as to cover the opening 69.
The cap 75 has an outer end 79 fitted to the reduced diameter portion 77, an inner peripheral edge 83 formed at the center of a motor shaft insertion hole 81 through which the right motor shaft 69 is inserted, and an opening formed by connecting them. The outer end 79 is in pressure contact with the elastic seal member 89 mounted in the recess 87 of the reduced diameter portion 77 to ensure the watertightness of the fitting portion. .
[0019]
Further, a substantially cylindrical elastic seal member 91 is interposed between the cap 75 and the end surface 73 of the motor 35 in order to prevent water from entering from the motor shaft insertion hole 81 through which the right motor shaft 71 is inserted. .
As shown in FIG. 2, the elastic seal member 91 is formed along the outer end flange portion 95 sandwiched by the cap 75 between the outer periphery of the bearing portion 93 of the motor 35 and the end surface 73, and the inner peripheral edge portion 83 of the cap 75. The inner periphery 97 is in contact with the outer periphery of the right motor shaft 71 in a sealed state, and the elastic seal member 91 prevents water from entering through the motor shaft insertion hole 81.
The cap 75 is supported via a bearing 101 on a disk-like support portion 99 projecting radially from the inner periphery of the spool 13, and the spool 13 includes the bearings 27 and 33 described above and the bearings. 101 is rotatably supported by the reel body 1.
[0020]
In FIG. 1, reference numeral 103 denotes a conventionally known speed reduction mechanism including three planetary gear mechanisms 105, 107, and 109. The speed reduction mechanism 103 is connected to the right motor shaft 71 protruding into the spool 13 from the motor shaft insertion hole 81. It is connected.
Between the right motor shaft 71 and the side plate 11, a rotational drive shaft 111 that transmits the winding power from the manual winding drive mechanism 21 to the speed reduction mechanism 103 is mounted coaxially with the right motor shaft 71. The rotary drive shaft 111 is rotatably supported between the bracket 29 and the side plate 11 via three bearings 113, 115 and 117. Then, the carrier 119 of the third planetary gear mechanism 109 is connected to the rotation drive shaft 111 via a locking pin 121.
[0021]
Further, on the rotation drive shaft 111, while applying a braking force to the spool 13 that rotates when the fishing line is fed, a braking action that allows the spool 13 to rotate in the fishing line feeding direction is given, and this braking action is utilized. A conventionally known drag device 123 having a clutch action for switching the spool 13 between a spool free state and a fishing line winding state is mounted, and a drag for adjusting the drag force of the drag device 123 on the side plate 11 on the rotation drive shaft 111 is mounted. A lever 125 is attached.
[0022]
The pinion 129 is fitted to the outer periphery of the pressing body 127 constituting the drag device 123 so as to be rotatable together with the pressing body 127, and the drive gear 131 of the manual winding drive mechanism 21 is engaged with the pinion gear 129. .
As is well known in the art, the manual winding drive mechanism 21 includes the handle 23 described above as shown in FIG. 1, the handle shaft 133 to which the handle 23 is attached, and the drive gear 131 that is fixed to the handle shaft 133.

Is provided.
[0023]
The reverse rotation prevention device 135 includes a ratchet 137 that is fixedly fitted to the handle shaft 133 and a locking claw (not shown) that is always locked to the ratchet 137 with a constant urging force. When the spool 13 is driven to wind, the latching claw engages with the ratchet 137 in the rotation direction, and the rotation of the ratchet 137, that is, the rotation of the handle shaft 133 is prevented.
[0024]
Accordingly, the driving force of the motor 35 is transmitted only to the spool 13 via the speed reduction mechanism 103.
On the other hand, when the spool 13 is rotated in the fishing line winding direction by the handle operation, the locking claw is configured to allow the ratchet 137 to rotate in the rotation direction. As a result, the handle 23 is rotated. The handle shaft 133 can be rotated in conjunction with the rotation.
[0025]
In FIG. 1, reference numeral 139 denotes a power supply cord connected to the connector 143 of the electric reel 141.
Since the present embodiment is configured as described above, in order to accommodate the motor 35 in the spool body 25 of the spool 13, first, the motor 35 to which the elastic seal members 57 and 91 are attached is attached to the elastic seal member 89. The cap 75 is accommodated in the accommodating body 15 that is attached to the end portion thereof. Thus, the outer end flange portion 95 of the elastic seal member 91 is sandwiched between the end surface 73 of the motor 35 and the cap 75, and the right motor shaft 71 protrudes from the motor shaft insertion hole 81 with a predetermined concentricity.
[0026]
Then, the support body 67 projecting from the support plate 17 is engaged with the recess 69 of the motor 35 to prevent the motor 35 from rotating, and the left motor shaft 37 with the one-way clutch 41 attached is attached to the support plate 17. After being inserted into the bearing support portion 39, the flange portion 45 may be fixed to the support plate 17 with screws 49, and the container 15 is pressed against the support plate 17 by tightening the screws 49, whereby the motor 35 is elastically sealed. The support plate 17, the container 15, and the cap 75 are held without backlash via the members 57 and 91.
[0027]
Further, in the process of tightening the screw 49, the concentricity of the left and right motor shafts 37, 71 is finely adjusted in the motor 35 by the elastic action of the elastic seal members 57, 58, 91.
Then, the support plate 17 to which the container 15 is fixed as described above may be screwed to the one side frame 5 of the frame 3 with screws 19, and in the process of tightening the screws 19, the elastic seal member 57 is used. , 58, 91 are finely adjusted so that the left and right motor shafts 37, 71 of the motor 35 are aligned with the axis of the spool 13 and the rotary drive shaft 111. The left and right motor shafts 37 and 71 are finely adjusted by the elastic action of the seal members 57, 58 and 91 so as to coincide with the shafts of the spool 13 and the rotary drive shaft 111.
[0028]
Furthermore, each elastic seal member 53, 57, 63, 89, 91 prevents intrusion of seawater, foreign matter, etc. into the inside.
As described above, according to this embodiment, when the motor 35 is housed in the spool 13 and when the motor 35 is driven, the concentricity of the left and right motor shafts 37 and 71 is set by the elastic action of the elastic seal members 57, 58 and 91. Since it can be ensured with high accuracy and ease, it is possible to avoid problems such as abnormal noise and vibration generated when the motor 35 is driven, and accelerated wear of the bearing and the drive unit.
[0029]
Further, there is an advantage that reliable water-tightness is ensured by the sealing action of the elastic seal members 57, 58, 91 for adjusting the shaft core and the other elastic seal members 53, 63, 89.
Furthermore, in this embodiment, when the side plate 9 is removed from the frame 3 and the support plate 17 is removed from the one side frame 5, the container 15 integrated with the side plate 9 is extracted from the spool 13 via the screw 49. Since there is no need to remove the motor 35 from the other side plate 11 side, the maintenance of the motor 35 and its drive unit can be easily performed. As a result, the maintenance workability is dramatically improved as compared with the prior art. Will be improved.
[0030]
FIG. 3 shows a second embodiment of the electric reel according to claim 1, and this embodiment replaces the elastic seal member 91 described above with an inner peripheral edge 97-contacting the outer periphery of the right motor shaft 71 of the motor 35. 1 is provided with an annular recess 145 having the right motor shaft 71 as an axis, thereby making the inner peripheral edge 97-1 partly thin and easily elastically deforming. It is used.
[0031]
In addition, since the other structure is the same as that of said 1st embodiment, the same code | symbol is attached | subjected to the same thing and those description is abbreviate | omitted.
Thus, according to the present embodiment, when the motor 35 is assembled, the elastic seal member 91-1 is sandwiched and pulled between the outer periphery of the bearing portion 93 of the motor 35 and the end surface 73 and deformed. Even so, since the thin-walled portion that is easily deformed elastically by providing the recess 145 extends and absorbs the deformation, the contact state between the outer periphery of the right motor shaft 71 and the inner peripheral edge 97-1 is stable. In addition to ensuring a reliable sealing property, there are advantages such as reducing the influence of unnecessary contact resistance with the right motor shaft 71 due to integration and dimensional variations.
[0035]
FIG. 4 shows a third embodiment of the electric reel according to claim 1, which is formed in the same shape as the above-described support plate 17 and is detachably supported on the one side frame 5 of the frame 3. The plate 17-1 is integrally formed with the container 15-1 having the same shape as the container 15 described above, and the other configuration is the same as that of the first embodiment of FIG. The same reference numerals are given and description thereof is omitted.
[0036]
Thus, in the electric reel 141-1 according to this embodiment, the motor 35 is accommodated in the accommodating body 15-1 from the opening 69 side. Since the concentricity of the left and right motor shafts 37 and 71 can be ensured with high accuracy and easily by the elastic action of the elastic seal members 57, 58 and 91 when the motor 35 is housed and attached and when the motor 35 is driven, It is possible to avoid problems such as abnormal noise and vibration generated during driving of the motor 35 and accelerated wear of the bearings and the drive unit, and the elastic seal members 57, 58, 91 for adjusting the shaft core and others. A reliable watertightness is ensured by the sealing action of the elastic sealing member 89.
[0037]
Furthermore, in this embodiment, when the motor 35 is maintained, if the side plate 9 is detached from the frame 3 and the support plate 17-1 is removed from the one side frame 5, the container 15-1 integrated therewith is attached to the spool 13 as well. Since the motor 35 can be extracted from the inside and the motor 35 is not required to be removed from the other side plate 11 side, there is an advantage that the maintenance workability is greatly improved as compared with the conventional case.
[0038]
【The invention's effect】
As described above, according to the first aspect of the present invention, without removing the left and right side plates attached to the frame, the housing for housing the motor from one side plate side is removed from the one side frame of the frame. Since cleaning, parts replacement, etc. can be performed, maintenance workability is significantly improved compared to the conventional case.
[0039]
In addition, according to the present invention , the motor can be housed in the housing body with watertightness, and the concentricity of the motor shaft can be ensured with high accuracy and ease when the motor is housed and driven. Therefore, it is possible to avoid problems such as abnormal noise and vibration generated during driving of the motor, and accelerated wear of the bearings and the drive unit.
