ることを特徴とする温度補償用バランサ。 A piston supported by a piston rod movably inserted into the cylinder divides the inside of the cylinder into an oil chamber and a gas chamber, and an outer tube is provided on the outside of the cylinder. In a temperature compensation balance mechanism in which an oil sump chamber communicating with the oil chamber is formed between the tube and the oil chamber, the working pressure is applied to a pressure receiving surface having an area smaller than the pressure receiving area of the piston on the oil chamber side through the oil sump chamber. A balance piston is slidably arranged in the cylinder with the pressure receiving surface on the other side facing the gas chamber, and the balance piston is moved in a direction to narrow the gas chamber when the hydraulic oil expands abnormally. A balancer for temperature compensation, characterized in that it is configured as follows.
