The tension balancer (1) is provided with an outer housing (20), an inner movable section (30), a coiled spring, and a pivotable connection section (60). The outer housing (20) formed in a tube-like shape is pivotably supported at the lower end thereof by the support (3) and is provided so that the outer housing (20) can be inverted. The inner movable section (30) is provided in such a manner that the inner movable section (30) is inserted through the outer housing (20), protrudes from the upper end of the outer housing (20), and can extend and retract in the axial direction of the outer housing. The coiled spring (40) is housed within the outer housing (20) and presses the inner movable section (30) in the direction in which the inner movable section (30) retracts. The pivotable connection section (60) has a fulcrum (82) which is pivotably supported by the support (3), a movable-section connecting point (84) to which the upper end of the inner movable section (30) is connected, and an overhead line connecting section (86) to which the overhead line for electric railway cars is connected, and the pivotable connection section (60) is provided so that the pivotable connection section (60) can pivot about the fulcrum (82).
