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 having a shape and being displaceable between a sealing position and an evacuation position, the shape being capable of sealing a gap occurring between the car-side door sill and the landing-side door sill , a side of the seal member being rotatably supported to a supporting member at a side of a door sill side of the elevator car ; and a link mechanism being released from an engagement with an actuating member at a car side to actuate when the car door starts to open from a door-close end, fixing the seal member while rotating the seal member at the sealing position, characterised by releasing the fixing of the seal member at a sealing position, and allowing the seal member to rotate to the evacuation position, wherein the link mechanism is released from the engagement with the actuating member to move down by a deadweight of component parts and to move upward by the engagement with the actuating member , the link mechanism includes a slide block , when the link mechanism moves down, the slide block pushes down one end of a rotation block provided coaxially to the rotation shaft of the rotation block to rotate the seal member to the sealing position, and the slide block moves upward to allow the seal member to rotate to the evacuation position. 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 having a shape and being displaceable between a sealing position and an evacuation position, the shape being capable of sealing a gap occurring between the car-side door sill and the landing-side door sill , a side of the seal member being rotatably supported to a supporting member at a side of a door sill side of the elevator car ; and a link mechanism being released from an engagement with an actuating member at a car side to actuate when the car door starts to open from a door-close end, fixing the seal member while rotating the seal member at the sealing position, characterised by releasing the fixing of the seal member at a sealing position, and allowing the seal member to rotate to the evacuation position, wherein the link mechanism is released from the engagement with the actuating member to move down by a deadweight of component parts and to move upward by the engagement with the actuating member , the link mechanism includes a slide block , when the link mechanism moves down, the slide block pushes down one end of a rotation block provided coaxially to the rotation shaft of the rotation block to rotate the seal member to the sealing position, and the slide block moves upward to allow the seal member to rotate to the evacuation position. <EOS>
