A combination structure of materials with a different kind is provided to have the leaf springs with a ring shape attached to the surfaces corresponding to both substrates. The first leaf spring(10) is attached at the first substrate(1). The second leaf spring(20) is attached at the second substrate(2) and matched with the first leaf spring. The two substrates are easily attached and detached with a sliding type. The first and second leaf springs are attached to proper positions in consideration of the size, weight and combining force of the first and second substrates and the relation with another construction. Plural leaf springs are used preferably in order to increase the combining force.
