Elevator car and elevator device using elevator car

The invention provides an elevator car and an elevator device using the elevator car. The elevator car has jointing structures of side plates which can ensure the mechanical strength of the wall faces of the elevator car and the shading property of the mutual joint positions of the side plates and can easily conduct side plate jointing working. The elevator car with the wall faces formed by connecting the multiple side plates is characterized in that each side plate is provided with a first joint face and a second joint face which are jointed with the adjacent side plates at one or more ends in the width direction; the first joint faces and the second joint faces are continuous faces located on the outer side of a car room of the elevator car and bended in the mode of direct crossing in the direction of the faces of the first joint faces and the second joint faces; the two adjacent side plates are configured in the mode that the first joint face and the second joint face of the side plate on one side cover th
