PURPOSE: A preventing structure of a movement for a sliding door is provided to firmly fix the upper part of the sliding door while opening the sliding door. CONSTITUTION: A roller fixing member(41) is formed in a door opening tip of an upper rail(11). In completely opening a sliding door, an upper roller is fixed by inserting in the roller fixing member. The fixing member comprises width reduction portions(41a,41b) and a combining portion(41c). The width reduction portions reduce the width of the upper rail gradually by arranging in both side potions(11a,11b) oppositely. The combining portion is fixed in a combining portion(11c) of the upper rail through a combining member(50) while connecting the tips of the width reduction portions. Thereby, the movement of the sliding door is prevented when the door is opened completely.
