PURPOSE:To prevent air from leaking out of a sensor cord, by extending the sensor cord out of the hole of a sensor case and filling synthetic resin in the case to embed sensor components, sensor lines and the tip of the sensor cord. CONSTITUTION:Sensor lines 41 connected to the lead terminals of a read switch 32 are collectively coated with a cord sheath 42 so that a sensor cord 4 is provided. The sensor cord 4 is extended out of the insertion hole 62 of a sensor case 6. Synthetic resin 7 such as epoxy resin is filled in the case 6 so that all the parts in the sensor case, such as the reed switch 32, sensor lines 41 and the end of the cord sheath 42, are embedded in the resin. Since the synthetic resin 7 is also filled in between the sheath 42 and the sensor lines 41, air is prevented from leaking out of the sensor cord 4. |
