Claims (1)

[Claims for Utility Model Registration] A hollow constant speed valve body that moves across a ventilation path as a push button is operated; and a cut that extends from the outer periphery to the hollow portion; A hollow constant speed valve with a bottom inserted into the hollow part, and a tapered surface on the outer periphery and a ventilation hole in the center, and the constant speed valve is inserted into the hollow part of the constant speed valve and has a gap in the constant speed valve. an adjusting body that increases or decreases the gap, and when the push button is in the normal position, airtightness is maintained between the outer periphery of the constant speed valve body and the air passage, and the air passage and the constant speed valve body are kept airtight. Constant-speed exhaust is performed through the hollow part, the constant-speed valve, and the regulating body ventilation hole, while when the push button is in the pressed position, the space between the outer periphery of the constant-speed valve body and the ventilation passage opens, and from there, the air is rapidly discharged. An exhaust valve for a blood pressure monitor characterized by exhausting air.
