A tracheal connector is connected to a respiratory gas generator and a tracheal tube. The tracheal connector includes a tracheal connector body connected to the tracheal tube, a connector tube connected to the tracheal connector body and the respiratory gas generator, and a restriction mechanism configured to narrow a respiratory gas flow path configured to allow the respiratory gas to flow therein. The tracheal connector body includes a tracheal port connected to the tracheal tube, an exhaust port facing the tracheal port and configured to discharge at least expired air of the subject, and a respiratory port connected to the connector tube. The restriction mechanism is provided on the respiratory gas flow path between the respiratory port and the tracheal port.
