摘要

Provided is a vapor jetting device including: a box-shaped casing (2); a propellant holding unit (3) that is placed in the casing (2) and forms a space for holding a propellant; a gas storing unit (4) that is placed in the casing (2), forms a space that is divided from the propellant holding unit (3) by a partition wall (21) including a communication hole (2a), and stores gas; a machine housing unit (5) that is placed in the casing (2), forms a space that is divided from the propellant holding unit (3) and the gas storing unit (4) by partition walls (21, 21'), and houses machines; a nozzle (6) that is connected to the casing (2) and ejects the gas to an outside; a gas flow path (7) that is formed in the casing (2) and supplies the gas stored in the gas storing unit (4) to the nozzle (6); and a heater (8) that is placed in the casing (2) and heats at least the gas storing unit (4).
