The invention discloses a cable-driven passive tensioning device of a deployable mechanism. The cable-driven passive tensioning device comprises a base, an upright, a swing arm, a swing arm seat, a swing arm shaft, a tensioning torsion spring, wire wheel mounting seats, wire wheels and an angle sensor. The upright is mounted in the middle of the base, the swing arm is coupled to the base, swinging of the swing arm is controlled through the tensioning torsion spring, and the swing arm is located on one side of the upright; the rotational angle of the swing arm is measured through the angle sensor; one wire wheel mounting seat is mounted at each of the top end of the upright, the middle of the lower surface of the base and the free end of the swing arm; the two wire wheels are coupled to each wire wheel mounting seat, and a threading passage is formed between every two corresponding wire wheels. The base is fixed to the fixed end of the deployable mechanism, and a driving cable of the deployable mechanism is connected with the movable end of the deployable mechanism by sequentially passing the base, the swing arm and the threading passage between the wire wheels on the wire wheel mounting seats on a top rod.
