A conventional parachute requires a velocity pressure during descent in order to open the parachute. As a result, a minimum descent distance and time are required from the beginning to the end of the parachute opening operation and use at low altitude has to be restricted. In order to remedy this issue, an airtight tube and a compressed gas device are provided together in a section of the parachute having the largest annular shape when the parachute has been opened. The tube is annularly expanded by the pressure of the gas, and the parachute is forcibly deployed and opened.
