PURPOSE: An apparatus for testing abrasion resistance of an underbody coating agent for a vehicle is provided to precisely measure a starting point of exposing a coating surface of a sample and to achieve reliability of a testing result. CONSTITUTION: An apparatus for testing abrasion resistance of an underbody coating agent for a vehicle includes a pipe(10), a height of which is controllable in a longitudinal direction thereof. A nut receiver(20) is aligned at a lower portion of the pipe(10) so as to precisely receive the nut(70) falling through the pipe(10). An opening and closing controller(40) is installed at an inlet of the pipe(10) in order to selectively open or close a falling outlet(12) of the nut(70) by an opening and closing control unit(41). A weight measuring device(50) is installed at the outlet so as to measure gross weight of the nut(70).
