An actuator is provided to enhance the convenience in opening and closing a slide part by having long slide stroke. One end of the first spring member(240) is pivotally connected to a main body and the other end is pivotally connected to a slide part. The first spring member converts the elastic deformation direction based on a predetermined turnover point. The second spring member(360) increases the elastic force in the elastic deformation direction of the first spring member in a part of the movement section of the first spring member. The second spring member selectively contacts between spring arms of the first spring member. According to both ends of the first spring member are separated from each other or get near to each other, the second spring member selectively contacts between both ends of the first spring member and is compressed or expanded.
