<p>To provide a molded coil capable of preventing the entrance of water, oil and the like into the inside a coil. ÄSolutionÜ A molded coil 1 is comprised of a coil 2 provided therein and having the outer surfaces thereof secondarily (?) covered by a resin material, and a molded element 17 formed by curing the resin material. Bulging portions 6 are provided at the opposite ends of a shaft 5 of a bobbin 3 of the coil 2. The molded element 17 is so formed as to cover the coil 2 from the outer surfaces of the two bulging portions 6 over the outer circumferential surface of the wound wire 4. On the outer surface of the lower bulging portion 6 is provided an embossed engaging portion in the form of a closed ring along the entire circumference of the bulging portion 6. Thus, even if water, oil or the like enters through mold detaching holes 18, it will not reach the inside of the coil 2. <IMAGE></p> |
