The present invention relates to a device for measuring the minimum ground height of a vehicle, the body 100 is formed with a vertical guide 110 having a predetermined height, and the upper surface (100A) of the body 100 is installed in the body 100 And a tape measure 150 which can be automatically pulled out by the elastic force of the spring S along with the guide 110 in the vertical direction, and formed on the upper surface 100A of the body 100 and displayed thereon. A bar height measuring device for a vehicle characterized in that it comprises a reading unit 140 to match the height of the drawer length of the tape measure 150 and the lower end of the body 100 to the tip of the tape measure 150 According to the present invention, when measuring the minimum elevation of a vehicle, the minimum elevation of the vehicle can be accurately converted to a numerical value by a single process, and the measurement of the minimum elevation, which is the height from the ground to various parts of the lower part of the vehicle, It has the effect of speeding up.
