Abstract
An air supply device includes a pump that delivers air, a connecting flow channel that connects the pump to an air bag, and a pressure reducing joint that reduces pressure of air supplied from the pump to the air bag. The pressure reducing joint includes an internal flow channel constituting a part of the connecting flow channel, and an exhaust flow channel that constantly connects the internal flow channel to the atmosphere and discharges a part of the air flowing through the internal flow channel to the atmosphere.
