The reel 5 is rotatably supported by the shaft portion 4 by rotatably fitting the shaft tube portion 9 provided at the center of the rear end plate 8 to the shaft portion 4. The cord 10 is wound around the outer periphery of the body 6. In this case, the length of the shaft portion 4 is set to approximately half the length of the body portion 6, and a stopper 11 is provided at the tip of the shaft portion 4 to prevent the shaft cylinder portion 9 from slipping forward. It is attached. Further, on the inner circumferential portion of the body portion 6, there are three protruding stripes 12 extending in the axial direction.
It is integrally formed at a location (only one location is shown in FIG. 1). On the other hand, the front end plate 7 has an annular shape with a circular opening 13 in the center.
A heat dissipation port 14 is formed around the periphery. 15
is a support plate made of synthetic resin installed in the opening 13 of the front end plate 7 so as to cover it;
A cylindrical portion 16 is protruded from the center of the front surface, and an annular wall 17 is protruded from the outer periphery of the back surface as shown in FIG. is formed. Also, this support board 1
5, three outlets 20 are screwed to the back surface located inside the annular wall 17 via a rubber base 19, and an electric leakage cutter 21 is screwed to the back side located inside the annular wall 17. A pilot lamp 22 is attached to the cylindrical portion 16 with a nut.
Of these, the front of each outlet 20 is provided with a support plate 15.
The cylindrical portion 24 of the base 19 is inserted into a hole 23 formed in the cylindrical portion 24 of the base 19 so as to be visible outwardly. 2
Reference numeral 5 denotes an outlet cap, which has three cap parts 2 attached to an annular mounting part 26 fitted into the cylindrical part 16.
7, each cap portion 27 is fitted onto each cylindrical portion 24 from the front in a watertight manner, thereby covering the front surface of each outlet 20.
Incidentally, reference numeral 28 denotes a cover that is openable and closable on the front surface of the support board 15 so as to cover the electric leakage switch 21 from the front.

On the other hand, 29 is a container-shaped waterproof cover with an open front end, which is made of relatively soft synthetic resin, and as shown in FIG. At the same time, a flange 32 is formed on the peripheral edge of this annular groove 31 and extends laterally, and the shaft 4 is formed in the center of the rear wall 29a.
A circular recess 33 for escaping is formed, and a cord insertion hole 34 is further formed on the outer periphery of the rear wall 29a. Further, in this case, six elongated screw insertion holes 35 are formed in the flange 32.
This waterproof cover 29 connects the annular groove 31 to the support plate 15.
By fitting into the annular wall 17 in a press-fitting state,
As shown in FIG. 4, the waterproof cover 29 is attached to the back side of the support board 15 in a watertight manner, and the electrical outlets 20, the leakage cutter 21, and the pilot lamp 22 are all covered by the waterproof cover 29. In this attached state, each screw insertion hole 18 of the support board 15 corresponds to three screw insertion holes 35 of the waterproof cover 29. Also, the cord insertion hole 34 of the waterproof cover 29
One end of the cord 10 is inserted through the waterproof cover 29, and inside the waterproof cover 29, the cord 10, each outlet 20, an earth leakage switch 21, and a pilot lamp 2 are connected.
2 are electrically connected. Furthermore, the cord insertion hole 34 is provided with a packing 36 as shown in FIG.
4 and the cord 10 are sealed watertightly.

With the waterproof cover 29 fitted to the support plate 15 in this manner, the support plate 15 together with the waterproof cover 29 is placed on the front surface of the peripheral edge of the opening 13 of the front end plate 7, and in this state, the fifth As shown in the figure, insert the tuft pin screw 37 into the body 6 through the screw insertion hole 18 of the support plate 15, the screw insertion hole 35 of the waterproof cover 29, and the screw insertion hole 38 at the peripheral edge of the opening 13 of the front end plate 7. The support plate 15, the waterproof cover 29, and the front end plate 7 are attached and fixed to the body 6 by tightening the front end of the protruding strip 13. Therefore, in this case, the flange 32 of the waterproof cover 29 is connected to the support plate 1.
5 and the front surface of the peripheral edge of the opening 13 of the front end plate 7.

According to this embodiment, in the body 6 of the reel 5, the outlet 20, the leakage switch 21, and the pilot lamp 22 are covered with the waterproof cover 29.
Even if water enters the body 6, the water will not splash on the outlet 20 or the like. Furthermore, in this case, if the waterproof cover 29 covering the outlet 20 etc. is simply fitted to the support plate 15, there is a risk that the fitting will come off due to vibration, etc., but according to this embodiment, the waterproof cover 29 The flange 32 is connected to the back surface of the support plate 15 and the opening 13 of the front end plate 7.
Since the supporting plate 15 and the waterproof cover 29 are fixed under pressure with the front surface of the peripheral edge thereof, the fitting between the supporting plate 15 and the waterproof cover 29 will not come off. Moreover, in this case, the waterproof cover 29 can be fixed at the same time as the support plate 15, so there is no need for a special fixing means, such as screws, etc., to fix the waterproof cover 29, simplifying the configuration. In addition, it is possible to improve the ease of assembly.

Incidentally, in the above embodiment, the tuft pin screw 37 was used as an example of the fixing means for fixing the support plate 15, but it goes without saying that it may be tightened with a bolt and a nut, for example. Also, if there is an electric leakage or disconnection 21
and a pilot lamp 22 may be provided as necessary.

[Effects of the invention] As is clear from the above description, according to the invention, even if water infiltrates into the body of the reel, the outlet is covered with a waterproof cover inside the body of the reel. It is possible to reliably prevent water from splashing on the outlet, and in this case, the waterproof cover covering the outlet is fixed by being sandwiched between the supporting board on which the outlet is attached and the end plate of the reel. , there is no need for a separate dedicated fixing means for fixing the waterproof cover, which simplifies the configuration, and
