により、取付け面ギャップを生じるため、耐水性に問題
が生じ。[Problem to be solved by the invention] Since the conventional outdoor sensor device is configured as described above, the center hole of the mold core according to the diameter of the electric wire cable is manufactured using a dedicated mold for each diameter. Alternatively, it was necessary to wrap insulating tape or the like around the tIL cable depending on the diameter. Additionally, the difference in thermal expansion coefficient between the outdoor resin and the electric wire cable creates a mounting surface gap, which causes problems with water resistance.
測定精度が低下する恐れがあった。There was a risk that measurement accuracy would decrease.
この発明は上記のような問題点を解消するためになされ

アネート化合物が考えられる。With the above configuration, the attachment part to the electric wire cable (14) is the rubber ring (13) made of outdoor liquid rubber, so you can simply set the rubber ring (13) of any diameter at the time of molding. Any diameter can be obtained. Therefore, it can be easily attached to the electric wire cable (14) without gaps, and since it is made of the same rubber material as the electric wire cable (14), there will be no gaps even if there are temperature differences due to seasonal changes. 6. The above liquid rubber for outdoor use includes a main ingredient which is a hydrogenated polyhydroxybutadiene polymer, one of which is an ultraviolet absorbing side and a light stabilizer, and an antioxidant, and a curing agent. A polyfunctional incyanate compound having two or more incyanate groups in the molecule is considered.
