Abstract
An overhead wire tension balancer can prevent an oil component in the tension balancer from scattering to the outside due to entry of rainwater. In an overhead wire tension balancer for supporting a spanned overhead wire while applying tension thereto, a gap that easily allows entry of rainwater is covered by a waterproof cover. As a result, the rainwater can be prevented from entering the inside of the overhead wire tension balancer, and the oil component separated from grease by entering rainwater can be prevented from scattering to the outside.
