  • Patent number: 8276316
    Abstract: The invention relates to a sliding door device including: a slider mounted to the sliding door so as to be movable on the rail; a lever provided in the slider so that a middle part thereof would be rotatable; a first roller provided on one end side of the lever so as to be rotatable on the rail; a recess formed in the rail so that the first roller would fall thereinto before the sliding door reaches a completely closed position, the recess having a rising wall surface of the rail being in a direction intersecting with a rotating surface of the first roller, the rising wall surface capable of coming into contact with the first roller; and a cable mounted to the sliding door for driving the sliding door to a closing direction when the cable is pulled. The cable is connected to the other end side of the lever and causes the lever to rotate in a direction that the first roller pushes the rail when the cable is pulled.
