Claim 1:
2. The cylinder drive device according to claim 1, wherein the plurality of holes of the manifold include a supply port configured to guide fluid from a fluid supply source thereto, at least one discharge port configured to discharge fluid to an outside of the manifold, a plurality of first connection ports communicating with the first cylinder chambers of the plurality of fluid pressure cylinders, and a plurality of second connection ports communicating with the second cylinder chambers of the plurality of fluid pressure cylinders,
the plurality of flow paths of the flow path unit include a third connection port configured to allow communication between the supply port and the one switching valve, a fourth connection port configured to allow communication between the at least one discharge port and the one switching valve, a fifth connection port configured to allow communication between the one switching valve and one of the first connection ports that communicates with the first cylinder chamber of the at least one fluid pressure cylinder via the throttle valve, a sixth connection port configured to allow communication between the one switching valve and one of the second connection ports that communicates with the second cylinder chamber of the at least one fluid pressure cylinder, and a seventh connection port configured to allow communication between the check valve and the one switching valve,
the one switching valve is configured to switch into a communication state or a blocking state between the third connection port and the fifth connection port, between the fourth connection port and the fifth connection port, between the fourth connection port and the sixth connection port, and between the sixth connection port and the seventh connection port,
at a first position of the one switching valve, the third connection port and the fifth connection port communicate with each other, the fourth connection port and the sixth connection port communicate with each other, and communication between the fourth connection port and the fifth connection port is blocked, and communication between the sixth connection port and the seventh connection port is blocked,
at a second position of the one switching valve, the fourth connection port and the fifth connection port communicate with each other, the sixth connection port and the seventh connection port communicate with each other, and communication between the third connection port and the fifth connection port is blocked, and communication between the fourth connection port and the sixth connection port is blocked.
