PROBLEM TO BE SOLVED: To adjust a top plate part on which a practicing person stands to an optional inclination angle in an optional direction and to simplify constitution. SOLUTION: A swing practicing base for an iron is constituted of: the top plate part 2 on which the practicing person stands; an upper stage spacer 3 and a lower stage spacer 4 piled up so as to support it from the lower part respectively in the shape of obliquely cutting a cylindrical container; a base rack 5 for supporting them, which is fixed to an installation surface; thrust bearings 6, 7 and 8 inserted between the top plate part 2 and the upper stage spacer 3, between the upper stage spacer 3 and the lower stage spacer 4 and between the lower stage spacer 4 and the base rack 5 respectively; an electric motor 9 for rotationally driving the upper stage spacer 3; and an electric motor 10 for rotationally driving the lower stage spacer 4. The upper stage spacer 3 and the lower stage spacer 4 can be turned independently, and the inclination direction and inclination angle of the top plate part 2 supported at the upper part are changed accompanying the turning.
