<p>PROBLEM TO BE SOLVED: To prevent a metallic peeled-off object generated at a bolt or a nut at a thread fastening part from dropping onto a circuit board, and prevent generation of looseness of the circuit board in an electric junction box completely by a simple structure. SOLUTION: This electric junction box 1 is constituted by forming a female connector 9 at a top cover 4 which covers the top of a circuit board 3 involving a plurality of bus bars 2, fixing a male connector 11 with a bolt 17, which is connected to the connector 9, supporting a nut 13 in which the bolt 17 is screwed, at a nut supporting part 12 in the female connector 9, forming a cylindrical hollow part 14 in the nut supporting part 12, and forming a scrap piece diffusion preventing part 19 on the circuit board 3, which is inserted in the cylindrical hollow part 14. It is thus possible to store a metallic peeled-off object 18 generated at the bolt 17 or the nut 13 in a recess 25 which is formed in a receiving pan part 23 of the scrap piece diffusion preventing part 19 for preventing it from dropping onto the circuit board 3.</p> |
