<p>PROBLEM TO BE SOLVED: To provide heat dissipation, when a relay is built in the case of an electrical junction box. SOLUTION: The case is formed with heat dissipation holes 10 at sections covering an outer end surfaces 6c facing the terminal protruding side of the relay 6, and heat dissipation ribs 11, bent inward at the whole periphery of each the dissipation holes. The front end of the heat dissipation rib is brought into contact with the peripheral edge of the outer end of the relay to close the case inside. The heat generation of the relay is transmitted to the case for heat dissipation via the heat dissipation rib, and the dissipation hole is formed with a louver 12.</p> |
