PURPOSE: An elastic pole for a tent is provided to regulate the length of a pole for a tent freely and easily and to keep firmly. CONSTITUTION: In an elastic pole for a tent, a cylindrical regulating bar(4), approaching to the top end of a large-diameter pole(2) to be unified with a fixed connection bar(3), having the inside diameter which is larger than the outside diameter of a small-diameter pole(1) and almost similar to the outside diameter of the large-diameter pole(2), and containing surrounding walls mixed and deflected by a thin wall(5a) and a thick wall(5b), is fitted compulsively to the outside of the large-diameter pole(2) by elasticity of the thin wall(5a) of the regulating bar(4) at the state of regulating the small-diameter pole(1) and the large-diameter pile(2) to the appointed length.
