PURPOSE: A transfer bogie and a guide rail are provided to freely determine the transfer direction of the same for transferring an article in order to minimize a transfer path for the article, thereby maximizing efficiency in transferring the article. CONSTITUTION: A guide rail (10) has protrusions oppositely protruding from both transverse ends thereof. A transfer bogie (30) on the guide rail runs along the extended direction of the guide rail. The bogie has a main frame, a pair of rotating frames, two pairs of rollers, and a rolling body. The rotating frames are rotatably coupled to the main frame. The rollers are rotatably coupled to the rotating frames, and are respectively placed at both transverse sides of the guide rail. The protrusion is inserted into a groove part at the outer circumferential surface of the roller. The rotatable rolling body rolls with being in contact with one side of the guide rail in order to prevent the roller from being separated from the guide rail. |
