For the purposes of improving the reliability of rolling stock, and savimg labor on maintenance, many electric devices are increasingly being carried on board instead of machine parts, such as cam, switch, etc. However, with the increase in the use of these electrical devices, there has also been an increase in the tendency for these devices to fail frequently. Therefore, the improvement in reliability of these electric devices has become a pressing matter. Based on this background, we have investigated the cause of failure and degradation condition of an electric device, and have found the factors that cause failure, and with what tendency. In addition, since the location of where the electric device is placed seemed to influence the driver's degradation greatly, its usage environment was investigated in detail. Finally, we carried out life an accelerated examination, and established a life evaluation technique for electric devices used in rolling stock.
