PROBLEM TO BE SOLVED: To provide a slip form device which can dispense with any additional driving device to separate a sliding form, and easily separate the sliding form in starting the work by making use of the driving force of a climbing jack. SOLUTION: This slip form device comprises sliding forms 11, 11 opposite to each other, a container to support both forms opposite to each other, and a climbing mechanism to vertically move the yoke, a reverse side of the sliding form 11 is connected to the yoke by pivotably supporting a diagonally upward expandable link 16 directed from the form to the yoke side and a diagonally downward non-expandable link 17 of a specified length at both ends by the yoke and the reverse side of the form so that the sliding form 11 is at a specified concrete forming position when the expandable link 16 is in the most- expanded condition.
