The present invention relates to a zipper type chain having a truss structure, which is applied to a drive device to transmit power for up and down movement, left and right movement, and front and back movement with respect to an installation surface of an object to be driven in manufacturing facilities in various manufacturing fields, transport facilities in a transport field, nursing facilities, stage equipment, a 3D printer module, or the like, and arranged to be crossed with each other to be a truss structure as corresponding unit joints are engaged. According to the present invention, a force of a vertical direction and a force of a horizontal direction are supported at the same time with a truss structure constituting a triangle. A first chain and a second chain are stably and securely engaged not to be easily broken and left during a working process of a drive device to maximize workability. Moreover, a smooth function is performed regardless of a size of an object to be driven and a drive device through simple assembly connection. Thus, manufacturing costs can be reduced, and productivity can be increased. |
