Claims

[Claims for Utility Model Registration] 1. A central hole of a bobbin around which a signal coil is wound and a storage portion formed at one end in the axial direction, and a head with a large diameter formed at one end. Insert the rod-shaped core so that the head is on the side of the storage part and the tip of the core protrudes from the front of the bobbin, insert a magnet into the storage part so that one side is in close contact with the head of the core, and The supporting part of the support column, which has an L-shaped side surface and an inverted T-shaped front surface and a mounting hole in the bottom part, is inserted into the storage part so as to be in close contact with the other surface of the magnet, and these parts are integrated into one piece. For those molded from resin, the axial thickness of the storage part formed on the bobbin is made larger than the total thickness of the core head thickness, the thickness of the magnet, and the thickness of the support part of the support column. In order to provide room for each component within the section to move in the axial direction, a through hole was provided at the center of the core of the support section of the support column, and synthetic resin was injected from behind the support section of the support column and molded into one piece. An ignition signal coil characterized by: 2. When injecting synthetic resin, cover the bobbin, core, magnet, etc. attached to the support column with a mold, and inject the synthetic resin from the injection port of the mold located behind the support column. , the leading end of the core protruding from the front of the bobbin is filled with synthetic resin while pushing the magnet forward through the through hole provided in the support part of the support column and into the outer periphery of the storage part and other parts. The ignition signal coil according to claim 1, wherein the signal coil is brought into contact with a mold.
