To provide a balancer which can reduce a change rate of tension, while being suppressed from enlarging in size.SOLUTION: A balancer according to the present invention comprises: an actuator that has a hydraulic cylinder, a hydraulic pump that supplies hydraulic oil to the hydraulic cylinder and a piston rod provided to freely advance and retreat with respect to the hydraulic cylinder, which is moved by hydraulic oil supplied to the hydraulic cylinder, which adjusts tension of a wire rod; a tension sensor provided between the wire rod and the actuator, which detects tension of the wire rod; a driving control part that controls the actuator on the basis of the tension of the wire rod detected by the tension sensor; and a corrosion preventing mechanism that prevents the piston rod from corroding.SELECTED DRAWING: Figure 1

    【課題】大型化を抑制しつつ、張力変化率を低減することができるバランサを提供すること。【解決手段】本発明に係るバランサは、油圧シリンダ、油圧シリンダに作動油を供給する油圧ポンプ、油圧シリンダに対して進退自在に設けられ、油圧シリンダに供給される作動油によって移動するピストンロッドを有し、線材の張力を調整するアクチュエータと、線材およびアクチュエータの間に設けられ、線材の張力を検出する張力センサと、張力センサが検出した線材の張力に基づいて、アクチュエータを制御する駆動制御部と、ピストンロッドを防錆する防錆機構と、を備える。【選択図】図1
