Toy parachute with throwing device, which is essentially characterized by comprising two separable parts, one of which is made of a thin sheet of plastic material, flexible and imporious and configured in the form of a spherical cap, being interdistanced and fixed to its annular rim a number of monofilar struts whose opposite ends converge and meet on a corporeal figure, the condition set being foldable and arranged so that around it a sheet comprised in the complementary part and on which it depends, attached thereto can be rolled. By a monofilar thread of a certain length, an element of greater mass and weight, preferably a ball, this complementary part being established as a throwing device of the first.
