The mounting surface side case 202 has a concave portion 202a at the center thereof for mounting the remote control cord 4 in a drip-proof and moisture-proof state. The concave portion 202a has a terminal corresponding to the terminal blocks 205a and 205b. Stand 205a,
A wiring window 202b for exposing 205b and connecting the remote control cord 4 is provided.

[0007] The remote control cord 4 is a two-core electric wire cord, and the core wires 401a and 401 exposed by removing the jacket.
b indicates that the center portion in the thickness direction of the annular rubber packing 206 for drip-proof and moisture-proof is closely attached from the outside to the inside (airtight).
State, and the connecting round terminal 402a,
402b is attached. The remote control cord 4 is provided with screws 207 for connecting the connection round terminals 402a and 402b to the terminal blocks 205a and 205b exposed from the wiring window 202b.
a and 207b.

Then, the annular rubber packing 206 is brought into contact with the concave portion 202a so as to surround the periphery of the wiring window 202b,
Put cover 208 from behind and screw 209a-209d
Thus, a drip-proof and moisture-proof structure for connecting the remote control cord 4 to the terminal blocks 205a and 205b is realized.

[0009]

In the connection between the remote controller for bathroom 3 and the remote controller cord 4 in such a remote controller for bathroom, the remote controller cord 4 to which the rubber packing 206 is attached is connected to the terminal block 205 of the controller 204.
Since the screwing work to be attached to a and 205b is performed at the installation site, it is often performed using a power tool. If the tightening torque is not properly controlled, an excessive tightening torque acts. Terminal blocks 205a, 205
b may be peeled off or the circuit board 204b may be damaged. Further, even after the screws are tightened and fixed, the external force when the remote control cord 4 is pulled by the subsequent work is still applied to the terminal block 2 via the core wires 401a and 401b.
05a, 205b, the terminal blocks 205a,
In some cases, the soldering of the 205b may be peeled off or the circuit board 204b may be damaged, resulting in a defective installation.

In order to penetrate the core wires 401a, 401b of the remote control cord 4 through the rubber packing 206, the tips of the core wires 401a, 401b are inserted into holes having a smaller diameter than the core wires 401a, 401b formed in the rubber packing 206. This is a work of penetrating in an airtight state, but the workability is poor because the rubber packing 206 is easily deformed, and if the rubber packing 206 is damaged, the adhesion (airtightness and watertightness) performance is reduced. Is tedious because it requires careful attention.

It is an object of the present invention to provide a waterproof and moisture-proof structure for connecting a remote controller and a remote controller cord with a simple structure and a solid structure.
