PURPOSE: A torsion testing device for a smart card is provided to fit a smart card by forming a groove in a front end and to repeatedly rotate jigs of both sides on a constant cycle for long time, thereby obtaining an exclusive torsion testing device for a smart card. CONSTITUTION: A torsion testing device for a smart card comprises a shaft(12), a lift rod(16), a jig(20), and a tilting link(24). The shaft is axis-joined to a motor(11), thereby being installed in a first fixing plate(13) to be rotated. The lift rod is eccentricity-joined to a rotating unit joined to both sides of the shaft, thereby vertically reciprocating. The jig forms a groove(22) in which a smart card(c) can be fitted, thereby being installed in a second fixing plate(23) to be rotated. The tilting link is joined to end parts of the jig and lift rod to be rotated, thereby rotating the jig. |
