RELEASE DEVICE

To provide a release device that can materialize motion of releasing a releasing object to a cosmic space, with simple structure.SOLUTION: An release device 100 comprises: a releasing object holding portion (cylindrical body 20) holding a releasing object 10; an energizing portion (a coil spring 80) energizing the releasing object 10; a transmitting portion 30 transmitting energizing force generated by the energizing portions to the releasing objects 10; a maintaining mechanism (a string-like body 50 for maintaining) causing the energizing portion to maintain a stand-by state in which the energizing portion does not energize the releasing objects 10; a releasing mechanism (a fusing device 55) releasing the maintaining mechanism thereby causing the energizing portion to transfer to a state in which the energizing portion energizes the releasing object 10; and engaging portion 70 which arranged integrally with the releasing object 10, and engages with the transmitting portion 30. When the maintaining mechanism is released by the releasing mechanism, and the energizing portion is transferred through the transmitting portion 30 to a state in which the energizing portion energizes the releasing objects 10, the engagement of the engaging portion 70 with the transmitting portion 30 is released in a course in which the releasing object 10 is energized and moved, and the releasing object 10 is therefore released from the releasing object holding portion.SELECTED DRAWING: Figure 4 【課題】放出物を宇宙空間で放出する動作を、シンプルな構造で実現することが可能な放出装置を提供する。【解決手段】放出装置１００は、放出物１０を保持する放出物保持部（筒状体２０）と、放出物１０を付勢する付勢部（コイルばね８０）と、付勢部による付勢力を放出物１０に伝達する伝達部３０と、付勢部が放出物１０を付勢しない待機状態に維持させる維持機構（維持用紐状体５０）と、維持機構を解除して付勢部が放出物１０を付勢する状態に移行させる解除機構（溶断装置５５）と、放出物１０と一体に設けられているとともに伝達部３０に対して係合している係合部７０と、を備え、解除機構により維持機構が解除されて付勢部が伝達部３０を介して放出物１０を付勢する状態に移行すると、放出物１０が付勢されて移動する過程で、伝達部３０に対する係合部７０の係合状態が解除されて、放出物１０が放出物保持部から放出される。【選択図】図４
