PROBLEM TO BE SOLVED: To reduce assembling manhour for fixing a connection lead wire which is stretched around the vicinity of a heat sink, with respect to a power supply circuit. SOLUTION: Two protruding parts 16b, 16c are formed on one side of the heat sink 16. A recessed part is formed of the protruding parts 16b, 16c. A duct 20 is partitioned and formed by making the recessed parts formed of the protruding parts 16b, 16c abut against each other. The connection lead wire 10 is accommodated in the duct 20. The other heat sink is made to abut against the recessed part 16d, or other component 22 is made to abut against the recessed par 16d. By accommodating the connection lead wire 10 in the duct 20 which is partitioned and formed by the recessed part 16d, the connection lead wire 10 is protected from heat generating components without needing a fixing member. |
