The tensioning device comprises a tensioning seat, a tensioning screw rod, a tensioning piece and a tensioning wheel, the tensioning seat is fixedly arranged, the tensioning screw rod is arranged on the tensioning seat in the mode that the tensioning screw rod can rotate in a single-freedom-degree reciprocating mode in the circumferential direction, and the tensioning wheel is arranged on the tensioning piece. The tensioning piece is arranged on the tensioning screw in a threaded fit mode and can be driven by the tensioning screw to reciprocate in the tensioning direction of the motorcycle transmission belt or the transmission chain. The tensioning wheel is arranged on the tensioning piece in a running fit mode and is in tensioning fit with the transmission belt or the transmission chain. The tensioning structure driven by threads is adopted, the tensioning state is adjusted through threaded connection, the structure is simple, cost is low, adjustment is easy, the stable tensioning effect is achieved, and therefore it is guaranteed that the transmission belt or the transmission chain is kept in the optimal working state for a long time.
