<p>PROBLEM TO BE SOLVED: To provide a chain driving device capable of suppressing undesired bending of a chain member advancing in a state of forming a stacked structure in a series direction, with a simple device constitution.SOLUTION: A chain driving device 11 includes a first chain member 28 bendable at one side, and having a block 45 positioned at the other side with respect to a connection shaft 43, and being brought into contact with the adjacent other block 45 to form a stacked structure 45A in a series direction, so that it cannot be bent at the other side, a first sprocket member 25 for advancing and retracting the first chain member by being rotated while engaged with the first chain member from one side, and a second chain member 30 restricting the bending to one side, of the first chain member in a state of forming the stacked structure, by applying a tensile force in a retracting direction to the first chain member at a position of the other side with respect to the connection shaft, of the first chain member advancing while forming the stacked structure.</p> |
