。 Hydraulic pressure from a hydraulic source is supplied to each oil chamber of a plurality of hydraulic cylinders via a supply path, each control valve, and each oil path to increase the cylinder pressure in each hydraulic cylinder, and the hydraulic pressure from each oil chamber is increased. In a hydraulic circuit configured to discharge hydraulic pressure into a tank via each oil passage, each control valve, and a discharge passage to reduce the cylinder pressure in each hydraulic cylinder, a communication passage that communicates the supply passage and the discharge passage is provided. An electromagnetic proportional relief valve is provided to set the oil pressure in the supply path, and each oil path is provided with a pilot shaft valve operated by pilot oil pressure via a pilot oil path communicating with the supply path. A hydraulic circuit characterized in that a throttle is disposed in a communication path that communicates between the oil passages, and an accumulator is further communicated with the supply path via the throttle.
