Fig. 4 is a schematic view of the elevator car 4 seen from the front. As shown in FIG. 4 , a vertical rolling door 14 is attached to the front of the elevator car 4 . The longitudinal type rolling door 14 is arranged to be automatically closed by the rolling door opening and closing device 16 before the elevator car 4 starts to travel. Thereby, even if the entrance/exit door 10 provided on the elevator car 4 is opened at a location other than the parking place (for example, in the middle of each floor), passengers can be reliably prevented from falling into the hoistway 3 . In addition, the vertical rolling door 14 is opened and closed in the vertical direction along a pair of guide rails 15 provided on the elevator car 4. When the elevator car 4 travels and when the elevator car 4 stops at a place other than the stop floor, The rolling shutter door opening and closing device 16 is automatically locked, thereby preventing accidents from occurring. The vertical rolling door 14 is installed so that the automatic lock of the rolling door opening and closing device 16 can be released in case of an emergency, and can be opened and closed manually. SS means the shutter door opening and closing sensor, FS means the floor detection sensor, DS means the entrance and exit door opening and closing sensor, MS means the manual control switch.
