PROBLEM TO BE SOLVED: To provide an aseismatic structure of a wooden framework capable of relieving a pedestal extraction force. SOLUTION: This aseismatic structure of a wooden framework includes a pair of columns 2, 2A, an upper horizontal member 3 and a base 1 which are joined to the columns 2, 2A, and earthquake-resisting walls 5, 6 provided between the pair of columns 2, 2A. An auxiliary column 11 is joined to the upper horizontal member 3, an intermediate horizontal member 4A, and the base 1 at a position apart from the column 2, and the upper part of the auxiliary column 11 and the upper part of the column 2 are joined to each other through a small wall 14. When a horizontal force acts on the upper horizontal member 3 from the column 2A side due to an earthquake, a compressive force X is generated at the lower part of the auxiliary column 11, and the extraction force at the lower part of the other column 2 is reduced according to the compressive force X. Also, the extraction forces acting on the columns 2, 2A are surely reduced since the column 2, the upper horizontal member 3, and the intermediate horizontal member 4A are firmly tightened.
