A semi-auto door device includes links(11,12), a guide block(20), a rod(30), and a door clip unit. The guide block is formed at upper surfaces of the links. The guide block has a hole. The rod is inserted into the hole of the guide block. The rod includes a fixing block(31). Another end of the rod is operated in association with the cylinder(40). When left and right doors are completely opened, the door clip unit fixes the left and right doors. When the rod is compressed by the cylinder, the fixing block pulls the guide block. The links automatically open the left and right doors. The left and right doors release a fixing force of the door clip unit to perform a closing operation with the links.
