Abstract
A tension balancer is disposed between an overhead line and a support, and maintains the tension of the overhead line. The tension balancer has an outer housing, an inner movable portion, a coil spring, and a pivotable connection portion. The outer housing is pivotably supported at the lower end by the support. The inner movable portion is inserted through the outer housing, protrudes from the upper end of the outer housing, and can extend and retract. The coil spring is housed within the outer housing and presses the inner movable portion so that the inner movable portion retracts. The pivotable connection portion has a fulcrum which is pivotably supported by the support, a movable-portion connecting point to which the upper end of the inner movable portion is connected, and an overhead line connecting portion to which the overhead line is connected.
