PROBLEM TO BE SOLVED: To provide a deposit recovery device which efficiently recovers deposits on the inside surface of a long and narrow pipe line which cannot be easily accessed by a person. SOLUTION: A recovery head of the recovery device for internal pipline deposits is provided with a deposit removal member whose diameter is increased/decreased by a conical cam, and a deposit guide member whose diameter is increased/decreased by a cylinder rod of an air cylinder. When the recovery head is entered into the pipeline, the deposit removal member and the deposit guide member are set smaller than the inner diameter of the pipeline. After the recovery head is entered into the pipeline, the deposit removal member and the deposit guide member are expanded and extended so as to be equal to the inner diameter of the pipeline, and then recovery work for the deposits inside the pipeline is performed; thereby the internal pipeline deposits are recovered efficiently.
