Abstract: To provide a flying object including a lift generating member deployment device that makes it easier than before to automatically avoid collision with an obstacle. A flying object 30 includes an obstacle detecting unit 5, a control unit 6, a battery 7, a storage unit 8 that stores information transmitted from the control unit 6, a transmitting/receiving unit 9 that receives an operation signal from a controller 40 and transmits information regarding the flying object 30 to the controller 40, and others. The obstacle detecting unit 5 is to detect the altitude of the flying object 30 and outputs an altitude detection signal, which represents the detected altitude information, to the control unit 6. In addition, upon detecting an obstacle present within a predetermined distance, the obstacle detecting unit 5 outputs an obstacle detection signal to the control unit 6, detects the distance between the flying object body 31 and the obstacle, and outputs a distance detection signal, which represents the detected distance information, to the control unit 6. The control unit 6 determines whether or not to actuate left and right brake cord pulling devices 10 in accordance with the signal received from the obstacle detecting unit 5.

Abstract: A gas generator includes a housing main body made of metal, a holder assembly, and an igniter. The holder assembly includes a holder portion made of metal and a connector portion made of resin. The holder portion includes a first barrel portion and an annular projection. The connector portion includes a second barrel portion and a cylindrical portion. The cylindrical portion is inserted in the housing main body and externally attached to the first barrel portion. As a portion of the housing main body corresponding to the cylindrical portion is decreased in diameter, the cylindrical portion is compressed by being sandwiched between the portion of the housing main body decreased in diameter and the first barrel portion so as to seal a gap between the housing main body and the first barrel portion.
