The present invention relates to a control device for a vehicle, including a first injection mechanism for injecting a paint onto an object, a power transmitting part for transmitting a driving force provided from the driving part to the first injection mechanism, a backlash adjusting part for adjusting a backlash of the first injection mechanism and the power transmitting part, And a guide mechanism for guiding rotation of the backlash adjuster such that the backlash adjuster is rotated around a first rotational axis, the power transmitter being eccentrically coupled to the backlash adjuster, the power transmitter being spaced apart from the first rotational shaft, Wherein the backlash adjuster rotates around the first rotation axis so that the power transmitting portion is moved to adjust backlash between the first injecting mechanism and the power transmitting portion and a coating robot . According to the present invention, since the backlash of the first injection mechanism and the power transmitting portion can be adjusted by rotating the adjusting body in a state where the power transmitting portion is inserted into the insertion hole, the backlash of the first injecting mechanism and the power transmitting portion can be controlled, Can be prevented from being generated.
