PURPOSE: A rigidity testing device of a door for a vehicle is provided to detect lower rigidity of the door by applying to continuous load through an actuator. CONSTITUTION: A door rigidity testing device comprises a plate(1); a chassis(5) supported by a frame(3) through being mounted on the plate; a displacement device(9) formed on a door(7); an installing bar(11) mounting the displacement device on the door; a ratchet unit(13) mounted on the door; a fixing band(15) holding the door by being installed on a side of the ratchet unit of the door; a pneumatic cylinder(17) installed on a side of the plate; a piston rod(19) operated front and back; a tonnage meter(21) fixed on an end portion of the piston rod; a connecting cable(23) engaging the tonnage meter with a lower end of the fixing band; a pulley(25) fixed on the plate; and an strain amplifier(27) amplifying a signal according to displacement and load.
