Abstract: A connecting device using a shape memory alloy (SMA). The connecting device uses an SMA, which firmly connects female member with male member inserted into the female member, in which a wire member formed of an SMA material is wound a plurality of times in a spiral shape, a hollow into which the female member is inserted is formed in a center portion of the spiral shape, and when the male member being inserted into the female member, the wire member presses against an outer circumferential surface of the female member to prevent the male member from being separated from the female member. According to the present invention, a connection is possible in a high-temperature phase corresponding to room temperature as well as in a low-temperature phase, and an allowable tolerance, which is a difference between a diameter of a hollow and an outer diameter of a female member, increases.
