To resuscitate the support and restoration functions of the lumbar and the pelvis which work as springs supporting the trunk by preventing a rubber tube from expanding more than needed when the band is worn, preventing a decrease in tightening force during use, and supporting the lumbar vertebrae, the sacrum, and the hip joint with a pad to provide elastic forces.

The main band 2 and the auxiliary band 3 of an elastic expandable cloth part 1 are integrally joined together with a narrow connection 4. A plurality of center nonexpendable cloth parts 6 and a plurality of end nonexpendable cloth parts 7 are provided for expandably retaining two rubber tubes 5 longitudinally on the main band 2 and one rubber tube 5 on the auxiliary band 3. The inner surface of each rubber tube 5 is folded back outwards to form knots 8 at each end of the rubber tube 5. The knots 8 are securely hooked in holes formed by narrowing the centers of the end nonexpendable cloth parts 7. The plurality of pads 10 support a joint to prevent dislocation. Hook-and-loop fasteners 11 are provided on the inner surfaces of the main bands 2 and the auxiliary band 3 at one end and on the outer surfaces of the main and auxiliary bands at the other.
