Zusammenfassung: | The present invention relates to a caterpillar structure for a screen door. More specifically, by forming an engaging unit on a connection projection which is to connect a plurality of caterpillars, when caterpillars are continuously connected, the present invention is able to prevent the caterpillars from being separated from each other due to conditions such as external impacts or twisting of the caterpillars and thus improves the stability of the opening/closing operation of a screen door. |
