To provide a drawer structure body employing roller rails, the structure body preventing the width directional wobble of a drawer body and implementing a smooth opening/closing operation.

The drawer structure body 1 includes the drawer body 60, a storage body 70, and a pair of roller rails 10a, 10b for allowing the drawer body 60 to be freely drawable with respect to the storage body 70. Each of the roller rails 10a includes an inner rail 11a attached to the drawer body 60 and an outer rail 21a attached to the storage body 70. The inner rail 11a and the outer rail 21a are arranged in such a way that the axial directions of the turning axes of the rollers 15a, 25a incline by 45 degrees to a horizontal direction. Even when a width directional force F₁ is applied to the drawer body 60, the movement of the drawer body 60 in the width direction is normally prevented by one of the roller rails 10a, 10b. Consequently, the width directional wobble of the drawer body 60 is prevented to implement a smooth opening/closing operation.
