PROBLEM TO BE SOLVED: To make easy right and left synchronization of a door with a simple construction by providing a plurality of a drive source incorporating type hydraulic equipment consisting of a hydraulic pump driven by a servo motor and a hydraulic operation terminal directly coupled to the pump. SOLUTION: For synchronization of operation amount to turn a door 2 displacement of a drive source integration type cylinder 3a is measured by a displacement inspection unit integrally incorporated in the cylinder 3a, and a displacment signal is outputted to a controller 9. Then, a feedback amount synchronization operated by a controller 9 is fed to a servo motor so as to perform control of a motor, and the cylinder 3a for turning the door 2 is synchronized. Accordingly, generation of an error in an operation amount is prevented so as to prevent generation of unnecessary deformation in the door 2. With such a constitution, hydraulic piping or oil tank is made unnecessary so that mulfunction in a facility caused by damage in the hydraulic piping is avoided.
