PURPOSE:To improve watertight property by extracting a lead wire for the molded transformer in a watertight and penetrating manner from a tube section integrally molded with a cover set up to a case in a watertight manner by an insulating elastic material. CONSTITUTION:The tube sections 12, 13 through which each lead wire 10, 11 at high voltage and low voltage penetrates severally are molded integrally to the cover manufactured by the insulating elastic material such as a synthetic rubber, and the inner diameters of each tube section 12, 13 are each made slightly smaller than the outer diameters of the high-voltage lead wires 10 and the low-voltage lead wire 11 passing through the tube sections. Accordingly, when the high-voltage lead wires 10 and the low-voltage lead wire 11 are penetrated into respective tube section 12, 13, the lead wires are brought to watertight states by the elasticity of the tube sections, and even when it rains or at inundation, water does not intrude from the sections. |
