<p>PROBLEM TO BE SOLVED: To provide an electrical junction box which enables the reduction of the penetration of water into a lower cover and, further, enables air circulation for heat radiation and has excellent reliability and durability. SOLUTION: An electrical junction box is composed of a main part 13 which holds electrical components 12, a lower cover 14 and an upper cover 16. A plurality of 1st locking parts 17 are formed on the outer circumference of the main part 13. 2nd locking parts 18 retained with the 1st locking parts 17 are formed on the inner wall 15 of the lower cover 14 so as to reach the bottom plate 20 of the lower cover 14. Mold holes 19 which are necessary for molding the 2nd locking parts are formed in the bottom plate 20 and, further, cross-walls 28 are formed as the parts lower than the parts of the 2nd locking parts which are necessary for retaining with the 1st locking parts 17, and notches 29 are provided at the bottom ends of the cross-walls 28.</p> |
