Even if the wiring extraction hole is filled with the sealing member, there is no need to remove the wiring by maintenance or the like, so that the sealing member does not have to be removed or the sealing member is refilled in the wiring mounting hole. For this reason, the intrusion of the liquid into the inside of the motor 4 from the outer surface of the motor holder 7 can be prevented with a simple structure.

<1st modification of 1st Example>

In the electric reel 110 of the 1st modification shown in FIG. 5, the motor holder 107 is formed integrally with the 1st side plate 113a of the frame 113 of the reel main body 102. As shown in FIG. Therefore, the bolt member 28 is unnecessary. The other points abbreviate | omit description for the same structure as the electric reel 10 of 1st Example shown in FIG.

<2nd Example>

In the electric reel 210 of 2nd Example shown in FIG. 6, the plan which fixes the connection part 207b of the motor holder 207 which fixes the motor 204, and the motor holder 207 to the 1st side plate 213a is shown. The configuration of the branch portion 207c is different from that of the first embodiment.

As shown to the B part of FIG. 6 to enlarge, the connection part 207b has the screw hole 248 and the screw member 250. As shown in FIG. The screw hole 248 has an inner circumferential surface 236e from the outer surface 236d of the engagement recess 236 such that the tip 248a is disposed at the other end side (right side in FIG. 6) of the motor case 220 rather than the base end 248b. It is formed obliquely toward. The screw member 250 is inserted into the screw hole 248 from the outer side surface 236d of the motor holder 207, and presses the outer peripheral surface 220f of the motor case 220 by the tip part 250a. The screw member 250 is, for example, a stop screw having a tool retaining portion 250c which is recessed in a hexagon to which, for example, a hexagon bar wrench (Wrench) engages at the base end of the screw shaft 250b. The screw member 250 is a concave tip in which the tip portion 250a is recessed. In the second embodiment of such a configuration, the tip 248a of the screw member 250 presses the outer circumferential surface 220f of the motor case 220 so that the motor case 220 is attached to the motor holder 207. Connected.

In the flange portion 207c, not a screw hole, a plurality of first through holes 207d through which the bolt member 228 can pass are formed at intervals in the circumferential direction. Further, in the first side plate 213a, second through holes 213f through which the bolt member 228 can penetrate at the same position as the first through hole 207d are arranged at intervals in the circumferential direction. An annular fixing member 252 is disposed between the first side plate 213a and the spool 3. In the fixing member 252, the screw hole 252a which can face the 1st through-hole 207d and the 2nd through-hole 213f is formed at intervals in the circumferential direction.

In the second embodiment, the bolt member 228 penetrates through the first through hole 207d and the second through hole 213f from the outer side surface of the flange portion 207c and is a screw hole 252a of the annular member 252. Are combined). Thereby, it is not necessary to provide a screw hole in the 1st side plate 213a or the motor holder 207, and those machining becomes easy. Moreover, compared with the case where each bolt member 228 is firmly tightened to a nut individually, the tightening operation | work of the bolt member 228 becomes easy. In addition, in this 2nd Example, the through-hole 7f provided in 1st Example is not provided in the cover part 207a of the engagement recessed part 236. As shown in FIG.

In the second embodiment having such a configuration, the screw member 250 is inserted into the screw hole 248 toward the outer circumferential surface 220f of the motor case 220. As a result, the tip of the screw member 250 arranged at an angle presses the outer circumferential surface 220f of the motor case 220 so that the motor 204 is fixed to the motor holder. Here, since the screw member 250 can be inserted at an angle, the base end of the screw member 250 is separated from the flange portion 207c, so that a tool for turning the screw member 250 is attached to the flange portion 207c. It becomes difficult to interfere. For this reason, the motor 204 can be easily fixed to the motor holder 207.

<Third Example>

In the motorized reels of the first and second embodiments, the motor was housed in the spool. However, as shown in FIG. 7, in the motorized reel 310 of the third embodiment, the motor 304 is connected to the spool 303. It is accommodated in the reel main body 302 from the front (FIG. 7 downward). The frame 313 of the reel unit 302 has a normal connecting member 313c for connecting the first side plate 313a and the second side plate 313b to the front of the spool 303. The normal connecting member 313c has a motor housing portion 313g therein.

The motor 304 differs in the structure of the motor case 320 from the first embodiment. In the motor case 320, the bottom part 320a and the cylinder part 320b are integrally formed. The motor holder 307 has a plurality of mounting arms (not shown) in which the mounting portion 307c does not have a flange portion and individually extends radially outward from the outer peripheral portion of the engagement recess 336. The tip of the attaching arm is fixed to the outer surface of the first side plate 313a by a bolt member.

In this manner, the present invention can also be applied to the motor 304 disposed in front of the spool 303.
