PURPOSE: An impact test apparatus is provided to prevent accident by permitting a user to control the test apparatus outside from the chamber, while improving accuracy of test result by dropping the weight from the precisely adjusted height. CONSTITUTION: An impact test apparatus comprises a main body(10) having a scale indicator(130), which is arranged to be height adjustable; a drop board(20) including an inclined passage(22) inclined downward so as to move a weight, and a drop exit(24) for discharging the weight moved along the inclined passage; and an open/shut unit(30) for selectively opening/shutting the drop exit. The main body includes a lower section(112) formed integrally with a support(114), an upper section(110) coupled to the lower section and which is movable in a vertical direction by a height adjustment unit(120). The open/shut unit includes an open/shut member(310) hinge-coupled to the drop exit; an elastic member(314) installed to a hinge coupled portion(312) of the open/shut member, which elastically rotates the open/shut member so as to shut the drop exit; and an operating member for pushing and rotating the upper surface of the open/shut member so as to open the drop exit.
