Abstract
An overhead wire tension balancer has a water draining structure and can prevent lubricating oil in the tension balancer from scattering to the outside. The overhead wire tension balancer is for supporting a spanned overhead wire while applying tension thereto, and rainwater collecting inside the overhead wire tension balancer is collected from a collecting pipe connecting part into a collecting tank through a collecting pipe. The oil content of grease applied to the inside of the overhead wire tension balancer is prevented from scattering to the outside even if the oil content is carried together with the rainwater.
