An elevator apparatus comprising: a car-side door sill configured to guide a car door provided in a doorway of an elevator car along its open/close direction; a landing-side door sill configured to guide a landing door provided in a doorway to the elevator car in each floor where the elevator car can be landed along its open/close direction; a seal member shaped to seal a gap between the car-side door sill and the landing-side door sill and slidable between a sealing position in which the gap is sealed and a retracted position; a link mechanism connected to the seal member, engaged with an actuating member of the car door side in synchronization with a car door open/close operation, and configured to convert a force received from the actuating member by the engagement with the actuating member into a sliding direction of the seal member to drive the seal member in the sliding direction, wherein the seal member is connected to an actuation spring that receives a movement force toward the sealing position, wherein the link mechanism releases the engagement force with the actuating member of the car door side in synchronization with a start of the door open operation from the door close end of the car door to permit sliding toward the sealing position by the actuation spring, and wherein the link mechanism is engaged with the actuating member of the car door side in synchronization with the movement of the car door toward the door close end, characterized in that the link mechanism is configured to slide the seal member placed in the sealing position to the retracted position resisting to a spring force of the actuation spring by the movement force of the car door. a car-side door sill configured to guide a car door provided in a doorway of an elevator car along its open/close direction; a landing-side door sill configured to guide a landing door provided in a doorway to the elevator car in each floor where the elevator car can be landed along its open/close direction; a seal member shaped to seal a gap between the car-side door sill and the landing-side door sill and slidable between a sealing position in which the gap is sealed and a retracted position; a link mechanism connected to the seal member, engaged with an actuating member of the car door side in synchronization with a car door open/close operation, and configured to convert a force received from the actuating member by the engagement with the actuating member into a sliding direction of the seal member to drive the seal member in the sliding direction, wherein the seal member is connected to an actuation spring that receives a movement force toward the sealing position, wherein the link mechanism releases the engagement force with the actuating member of the car door side in synchronization with a start of the door open operation from the door close end of the car door to permit sliding toward the sealing position by the actuation spring, and wherein the link mechanism is engaged with the actuating member of the car door side in synchronization with the movement of the car door toward the door close end, characterized in that the link mechanism is configured to slide the seal member placed in the sealing position to the retracted position resisting to a spring force of the actuation spring by the movement force of the car door.
