Abstract: The present invention relates to a connecting device using a shape memory alloy, which is used for firmly coupling a female member with an insertion hole and a male member to be inserted into the insertion hole of the female member. The connecting device is formed with a wire rod made of shape memory alloy and helically wound several times and a hollow core which is formed in the center portion of the helical shape, and into which the female member is inserted. The connecting device is characterized by pressurizing an outer circumferential surface of the female member in a state where the male member is inserted into the insertion hole of the female member, thereby preventing the male member from being separated from the insertion hole of the female member. According to the present invention, it becomes possible to perform a connecting work on an austenite phase at room temperature as well as on a low temperature phase and a gap tolerance between a diameter of the hollow core and an external diameter of the female member may be increased.
