Let(X.d) be a T-admissible space. Let 2?? and C(X) be the hyperspaces of nonempty closed subsets and subcontinua respectively and endow with the Hausdorff metric H. In this paper, we investigate the properties of T-admissible spaces and the conditions for contractible hyperspaces. And then, we shall give the following result; "Let A∈A(x)∩C(??), Then ∀ε > 0, ∃B∈A(x)∩C(A)∋B⊂A, H(A, B) < ε" (Theorem 2).
