A speed monitoring device for a passenger conveying device includes a transmission rotor (100) disposed on a shaft side surface of a shaft (800) of which the speed is to be measured and rotating with rotation of the shaft (800) of which the speed is to be measured; an encoder (200) having an input shaft (210), the input shaft (210) of the encoder (200) being connected to the transmission rotor (100) and rotating with rotation of the transmission rotor (100); and a mounting bracket (300) for securing the transmission rotor (100) and the encoder (200) to a position where they are to be mounted. According to the speed monitoring device and the passenger conveying device of the present application, by properly designing the structure of the speed monitoring device and arranging it on the shaft side surface of the main drive shaft (800), the stability of monitoring the rotational speed of the shaft (800) can be ensured on the one hand, and on the other hand, there is more space reserved around the mounting position for easy maintenance and service.
