うになる。Here, since the outer walls 23 and 27 of the power supply box body 12 and the lid 13 are meshed with each other by the L-shaped portion and the inverted L-shaped portion at the tips thereof to be polymerized, rainwater and the like can be easily carried out. It does not infiltrate, but by any chance, the above-mentioned outer walls 2
Even when rainwater enters from the L-shaped meshing portions of 3, 27, the infiltrated rainwater passes through the upper groove 28 to the lower groove 24 provided between the outer side walls 23, 27 and the inner side walls 22, 26. It comes to be discharged to the outside through the holes 25a and 25b.

However, this does not penetrate into the inside of the power supply box and is again discharged to the outside through the water drain holes 25a and 25b. If by any chance strong wind causes pressure, the water drain holes 25a and 25b,
Even if rainwater is blown into the lower groove 24 from 25b, the blown rainwater is once guided in the direction of the upper groove 28 having a large space volume, and drops into the lower groove 24 again to drain water holes 25a and 25b.
Will be discharged from the outside. This reliably prevents rainwater and the like from entering the inside of the power supply box in which various electric components are arranged.

形や折損が生じることはない。In this case, the outward bending amount of the lock piece mounting portion 29a due to the pushing up of the lock piece 29 of the lid 13 is limited to the minimum necessary by the limiting frame 31 and its leaf spring portion 31a. The deformation or breakage of the lock piece attachment portion 29a does not occur.

The side wall of the lid 13 and the side wall of the lid 13 are double side walls composed of the inner side walls 22 and 26 and the outer side walls 23 and 27, and the inner side surface of the lid inner side wall 26 is slidably pressed onto the outer side surface of the main body inner side wall 22. Then, the tip end L-shaped portion of the main body outer side wall 23 is brought into contact with the tip end inverted L-shaped portion of the lid outer side wall 27 so as to come into contact therewith, and if it enters from the abutting portion between the outer side walls 23, 27. Rainwater also
Rainwater blown through the drainage holes 25a and 25b is also allowed in the space formed by the lower groove 24 and the upper groove 28 provided between the inner side walls 22 and 26 and the outer side walls 23 and 27 to allow the rainwater to flow through the drainage holes 25a and 25a. Since it is configured to be discharged from 25b to the outside, it is possible to reliably prevent rainwater and the like from entering the inside of the power feeding box in which various electric parts are arranged. Sufficient waterproofness can be obtained without sealing.
