PURPOSE: A door checker of a vehicle is provided to maintain stable opening and shutting force of a door even under low temperature, to reduce a friction noise in opening and shutting, to prevent deterioration of a detent feeling caused by wear of a plate and rollers, and to reduce the length of processes and the cost through simplification of the structure. CONSTITUTION: A door checker of a vehicle includes a plate(30) and bush-shaped rollers(40). A support bracket(10) bolted to a vehicle body is fixed to one side of the plate. A stopper(20) is fixed to the other side of the plate. The plate comprises a leaf spring of a symmetrical shape having at least one protrusion and groove. The bush-shaped roller is slidably installed to the outside of the plate and is fixed to a door inside panel of the vehicle. A longitudinal groove is formed to the outside of the plate along the longitudinal direction, to reduce the sliding resistance with the rollers. The protrusions and grooves of the plate are formed through bending of the plate.
