PROBLEM TO BE SOLVED: To provide oil cooler structure of a construction machine to reduce the manufacturing cost, minimize the space, and extend the service life. SOLUTION: A connection component is provided to an oil inlet pipe and an oil supply pipe, and the connection component is provided to an oil outlet pipe and an oil return pipe to connect the between of the respective connection components with an elastic pipe. The connection component of the oil inlet pipe is inclined downward and the connection component of the oil return pipe is inclined upward and outward. The maximum bending of an elastic hose is obtained in a swing-in state of the oil cooler. The bending of the elastic hose is reduced when the oil cooler is swung out, and the torsion of the elastic hose is made within a predetermined range. COPYRIGHT: (C)2004,JPO
