Abstract:
1. A side sliding door apparatus for a vehicle, comprising: two sliding doors movably suspended from a horizontal door rail attached to the vehicle; an actuator coupled to one of the sliding doors so as to be movable for a certain distance relative to an opening direction of the one sliding door; a direction converting mechanism that converts a direction of an opening and closing movement of the one sliding door and conveys a conversion to the other of the sliding doors; a locking mechanism provided on the direction converting mechanism; and a push fitting and pull fitting provided on the actuator; wherein the locking mechanism comprises a slider supported so as to be slidable in the direction of the movement of the one sliding door and having a cam surface and a rear edge, a back spring that pushes on the rear edge of the slider and biases the slider in a closing direction of the other sliding door, a latch having a roller that contacts the cam surface of the slider and move, and a lock spring that biases the latch in a downward direction, wherein when the one sliding door reaches a closed position at a time of closing the sliding doors, the actuator pushes the slider using the push fitting, causing the roller to drop to a lower portion of the cam surface and locking the sliding doors in a closed condition with the latch, while when opening the sliding doors, the actuator that moves for the certain distance in the opening direction pulls the slider using the pull fitting, pushing the roller up to an upper portion of the cam surface and releasing the locking of the sliding doors with the latch, and wherein the cam surface formed on the slider includes an upper inclined surface extending gradually and continuously upwardly from the rear edge of the slider to a top portion, and an inner inclined surface extending downwardly from the top portion at a side opposite to the upper inclined surface.
