PURPOSE: To obtain the compact constitution of a propeller guard from a propeller guard body for accommodating a propeller and propeller guard divided bodies, in the constitution in which the propeller surrounded by the propeller guard is installed on a frame connected by a suspended cable on a wing-shaped parachute.

CONSTITUTION: As for the structure in which the upper part of a frame 1 is connected with a wing-shaped parachute (not shown in the figure) for generating a lift during gliding through a suspension cable 2 and a riser belt 3, a harness for holding the body of a pilot M is installed forwardly on the frame 1, and a power unit 8 equipped width a propeller 5 is installed rearward, and the front part on the pilot M side of the power unit 8 is surrounded by a propeller guard 6. The propeller guard 6 is constituted of a propeller guard body 10 for accommodating the power unit 8 in which the propeller 5 and an engine 7 are formed integrally, and the left and right propeller guard divided bodies 11a and 11b which are foldable through the hinge-joint by using a pin 10a on the propeller guard body 10.
