PURPOSE: A rear wheel spin preventing device is provided to control an injection pump with a cylinder of electronic operation, to use an engine integrated controller without using an additional controller and to prevent a spin of the rear wheel. CONSTITUTION: A device for preventing a spin of a rear wheel comprises an engine integrated controller(E.C.U) outputting control current to reduce an output of an engine by detecting velocity of rear and front wheels with a speed sensing sensor; a control cylinder(2) operated by receiving the control current; a 2-axes link(4) supporting a return spring on a recessed portion and connecting to the control cylinder in a front end portion; and a control arm(6) controlling driving speed of an injection pump(5) according to the movement of the 2-axes link by being engaged with the 2-axes link in the other front end portion. The difference of velocity is generated when friction coefficient of front and rear wheels is different. The engine-integrated controller detects the difference of the velocity to prevent spin of the rear wheel by dropping driving speed of the injection pump.
