The device, for preventing the reverse rotation of the driving shaft in the transmission, connected with shifting gears prevents traffic accident on hilly road from the reverse driving and promotes soft gear-changing in the middle of shifting gears from rear driving to front driving. The device comprises a driving shaft (1) for connecting the transmission with differential gears, having a helical spline (1b) engaged with rotary reciprocating gear (6); reverse-rotation preventing gear (2a) mounted on the hub (1a) of the shaft (1) and combined with one-way clutch bearing (2) on the transmission gear case (8); fork (4) supported by spring of transmission rod (9) and combined with sleeve (3) for connecting (1a) with (2a); induction gear (5) engaged with the gear (6), connected with link (7).
