When high-pressure air is blown from zero, an air curtain surrounding the sensing area of the sensor 7 is formed by the high-pressure air, and rain or snow is blown out of the sensing area. Measurement can be performed, and the charging operation can be performed by securely connecting the power supply coupler 2 to the charging coupler 6.
