Abstract

본 발명은 자동차에 구비되는 부품의 시험장치에 관한 것으로, 특히 운동량이 많은 임의의 부품 종단부에 삽입되어 완충 및 마모율을 감소시켜 주는 그로멧(Grommet)에 대한 내구성 시험에서 검출되는 시험결과를 저장함과 동시에 표시수단을 통해 디스플레이 하며, 그로멧의 파손이 검출되면 시험동작의 진행을 중지하도록 하여 그로멧의 내구성 시험에 신뢰성을 제공한다.The present invention relates to a test apparatus for a component provided in an automobile, and particularly, to store test results detected in a durability test for a grommet inserted into an end portion of a part having a high momentum to reduce the buffer and the wear rate. At the same time, it is displayed through the display means, and if the breakage of the grommet is detected, the test operation is stopped to provide reliability to the durability test of the grommet.
