PURPOSE: To facilitate assembling and perfectly absorb an external force by providing a knot to the power supply cord extended through a bushing and molding such knot with an insulator.
CONSTITUTION: A bushing 10 is provided to a part of case 8 and this bushing 10 allows insertion of a power supply cord 12 having a connection plug 11 at the one end thereof. A knot of cord 12 is provided near the bushing 10 in the case 8 and an external force absorbing part which is obtained by molding an insulator 13 is provided to such knot. Moreover, an electronic part such as transformer 9 is connected to the other end of cord 12. With such a structure, the knot of cord 12 is no longer united and such absorbing portion absorbes an external force applied on the bushing, protecting the connecting part from destruction.
