1. A slide rail comprising:

  • a fixed rail including a rectangular-shaped first plate and a pair of first bent parts, each of the pair of first bent parts having one end being continuous with both ends in the width direction of the first plate, the each of the pair of first bent parts being bent in the depth direction of the first plate so that the other ends approach each other;

    an intermediate rail including a rectangular-shaped second plate opposed to the first plate and a pair of second bent parts which is continuous with both ends in the width direction of the second plate at one end thereof and is bent in one direction so that the other ends approach each other, the intermediate rail disposed inside the fixed rail and slidable relative to the fixed rail reciprocally along a longitudinal direction of the first plate, and the second bent parts bending in a same direction as that of the first bent parts;

    a movable rail including a rectangular-shaped third plate opposed to the second plate and a pair of third bent parts which is continuous with both ends in the width direction of the third plate at one end thereof and is bent in a direction so that the other ends thereof approach each other, the movable rail disposed inside the intermediate rail and slidable relative to the intermediate rail reciprocally along a longitudinal direction of the second plate both in the pulling-out and the pushing-in directions, and the third bent parts bending in a direction opposite that of the first bent parts;

    a first roller mounted to the fixed rail at a proximal end in the pulling-out direction thereof and slidable on an outer below surface of the pair of second bent parts;

    a second roller mounted to the intermediate rail at a distal end in the pushing-in direction thereof and slidable on an inner surface of the pair of first bent parts;

    a third roller mounted to the intermediate rail at a proximal end in the pulling-out direction thereof and slidable on an inner surface of the pair of third bent parts; and

    a fourth roller mounted to the movable rail at a distal end in the pushing-in direction thereof and slidable on an inner surface of the pair of second bent parts.
