ABSTRACT:
A side sliding door apparatus for an electric railcar includes two sliding doors movably supported by a horizontal door rail to open and close an entrance of the electric railcar. The side sliding door apparatus includes an actuator for actuating the sliding door, a locking mechanism for locking the sliding door in a closed state, and an unlocking mechanism for unlocking the sliding door locked by the locking mechanism. The actuator, the locking mechanism, and the unlocking mechanism are provided in each of the two sliding doors. The right and left actuators operate independently from each other, and thus, even if the actuator for one sliding door breaks down, the other sliding door still can be used.
