PURPOSE: A spring type filter bag cage is provided to obtain superior dust eliminating efficiency by stretching the body part of the filter bag cage to the longitudinal direction in case of an air pulsing-based dust eliminating operation. CONSTITUTION: A spring type filter bag cage includes a body part(32), an upper cap(34), and a lower cap(36). The body part includes a pre-set length along a stretching direction. The body part is formed into a coil-spring shape. The upper cap is combined with the upper side of the body part. The upper side and the lower side of the upper cap are opened. A fixing ring with a through hole is located at the center part of the upper cap. The fixing ring is fixed to the upper cap based on the fixing ring. The lower cap is combined with the lower side of the body part. One end part of the lower cap is closed.
