The present invention relates to a shock-absorbing support device for an idler of a crawler track, which controls tension by being connected between a support frame and an idler support arranged in a track of the crawler track. The shock-absorbing support device for an idler has a gas shock absorbing unit wherein inert gas is charged in one end and the rear end is sealed by an inner piston, and a shock absorbing hollow unit wherein a first working fluid is charged in the other end. The gas shock absorbing unit and the shock absorbing hollow unit include: a two-stage cylinder frame connected by a connection flow path; a connection rod unit of which front end is inserted into the shock absorbing hollow unit; and a guide groove unit in which the rear end of the connection rod unit is inserted therein and a second working fluid is filled therein. The guide groove unit includes an auxiliary cylinder unit having a check valve for supplying the second working fluid.

    무한궤도의 트랙 내부에 배치된 아이들러 지지대와 지지프레임 사이에 연결되어 장력을 조절하는 무한궤도의 아이들러 완충지지장치에 있어서, 일단부 내부에 불활성기체가 충진되되 후단부가 내부피스톤에 의해 밀폐된 기체완충부가 형성되고, 타단부의 내부에 제1작동유체가 충진되는 완충중공부가 일체로 형성되며, 상기 기체완충부 및 상기 완충중공부는 연결유로에 의해 연통되는 2단 실린더 프레임; 전단부가 상기 완충중공부에 내삽되는 연결로드부; 및 상기 연결로드부의 후단부가 내삽되고 내부에 제2작동유체가 충진되는 가이드홈부가 형성되되, 상기 가이드홈부에는 제2작동유체 보충을 위한 체크밸브가 구비된 보조실린더부를 포함하는 무한궤도의 아이들러 완충지지장치를 제공한다.
