Abstract
An overhead wire tension balancer can prevent rotation of an inner cylinder connected with an overhead wire, without deteriorating rotation preventing function, even if stroke is increased, and does not complicate production steps. A rotation preventing plate is formed at the inside of an inner cylinder, and an opening which cannot rotate relative to the rotation preventing plate and which can relatively move in a condition which passes a long plate, is formed on the rotation preventing plate. The long plate is formed by two long plate pieces in an L shape in which a tip is bent, a hanging portion is formed by this bent portion and prevents the rotation preventing plate from disengaging from the long plate.
