An elevator capable of supplying electric power to accessory hall devices such as up/down elevator buttons and position indicators without requiring power supply lines between the cage and each hall. A drive battery which supplies electric power to hall devices provided in each hall and a receptor connected to the battery are provided on the hall. A feeder contactable with the respective receptors, a charging device that charges the battery via the feeder and receptor are provided on the top of the cage. When the charging voltage, for example, used in a hall of the floor drops below a predetermined voltage value, the cage stops automatically at the floor and the charger charges the drive battery in the hall of the floor via the receptors and feeder.
