A sequence valve is interposed in the discharge oil path of a hydraulic actuator drive circuit including a hydraulic switching valve, and oil flows from the discharge oil path side branched from the discharge oil path upstream of the sequence valve No. 4. The sequence valve is configured such that oil flows into the accumulator via a branch circuit equipped with a check valve that only allows for The accumulator pressure accumulation circuit is provided with a bypass passage connecting the upstream side and the downstream side of the sequence valve in the discharge oil passage, and the bypass passage is provided with a bypass passage that opens when the hydraulic pressure switching valve is in a closed operation position when it is in a neutral position. (An accumulator pressure accumulation circuit characterized in that it is equipped with an on-off valve that is controlled to open and close in conjunction with the operation of a hydraulic pressure switching valve.
