| 摘要 | PURPOSE: To enable disconnection of a lead wire between an electrode and a collision detection circuit main body to be detected positively by providing an electrical resistor between electrodes which a magnetization inertial body contacts with and by forming both electrodes and the electrical resistor in one piece by insert molding of a synthetic resin. CONSTITUTION: Electrodes 40 and 42 are formed as one part of conductive pieces 46 and 48 which consist of a pressed sheet material which is made of a thin copper plate. An electrical resistor 54 is erected between conduction pieces 46 and 48 and a main part of the conduction pieces 46 and 48 is buried within a conductor holder. This configuration allows the electrical resistor 54 to be positioned closest to the electrodes 40 and 42 so that disconnection closest to the electrode can be positively detected. Also, since a large part of the electrodes 40 and 42 and the electrical resistor 54 can be buried into a synthetic resin, the electrode and electrical resistor can also be protected.
