PROBLEM TO BE SOLVED: To provide the deformation restraining structure of a tower structure minimizing influence caused by flexural deformation of the tower structure itself located below a post member by holding the post member vertically even when the lower end of the post member fitted to a structure body is horizontally displaced or inclines. SOLUTION: The deformation restraining structure restrains the deformation of a top part of a communication tower (the tower structure) 10 having the post member 30 for supporting an antenna, and a long-sized steel frame part 22 supporting the post member 30 by the top part through a holding member 40. The holding member 40 positions the respective center axes 22a, 30a of the steel frame part 22 and the post member 30 on the same straight line in a vertical direction in a normal state and absorbs the relative displacement of the respective center axes which occurs between the steel frame part 22 and the post member 30 when the steel frame part 22 is horizontally displaced or inclines.
