Abstract
In a mask device with blower, a sensor for warning is disposed, which detects a movement position of an exhaust valve corresponding to the case where an internal pressure of a face body is lower than an outer atmospheric pressure at the time of inhaling air in a non-contact state and outputs a signal. A warning device operates in accordance with a signal that is output from the sensor for warning.
