が起こる恐れがある。However, in such a conventional structure, the dimensions of the molded material of the lead bushing 4 have a tolerance two orders of magnitude larger than that of a metal product due to manufacturing reasons. For this reason, if the temperature of the terminal part of the device rises abnormally for some reason, or the pressure of high-pressure liquid rises abnormally, the O-ring 6 seal that has been maintaining a water seal will change due to the size of the sealing surface. It was not possible to adequately deal with the abnormal phenomenon due to the lack of woodiness, deterioration of material properties due to the temperature rise of the mold material, and deterioration in quality. Therefore, there is a possibility that liquid may be ejected to the outside of the machine.
