Abstract
There is provided a safety apparatus including a push-up member in which an ejected object is hardly displaced even during transportation, and an aerial vehicle including the safety apparatus. A safety apparatus 100 includes a cylinder 14 that accommodates a piston member 10 and is provided with a bore 13 through which the piston member 10 protrudes to the outside (upward in FIG. 1) during operation, a push-up member 15 that is pushed up in one direction by the piston member 10, an ejected object 16 that is pushed up while being supported by the push-up member 15, a gas generator 17 as a power source that moves the piston member 10 in the cylinder 14, a container 18 that has a bottomed cylindrical shape and accommodates the piston member 10, the cylinder 14, the push-up member 15, the ejected object 16, and the gas generator 17, and a lid 21 that closes an opening end of the container 18. A movement preventing member 27 that prevents the ejected object 16 from moving in a circumferential direction of a bottomed cylindrical portion 19 is provided on an upper surface of a support 20 of the push-up member 15.
