<P>PROBLEM TO BE SOLVED: To solve a problem that a conventional wing-opening device uses a spring for a wing-opening drive source, has a complicated structure and is likely to be expensive, accordingly. <P>SOLUTION: A plurality of wing bodies S rotatable in the front-back direction of a flying object R is provided, each of wing bodies S is rotatable in a range from a housed position along an outer surface of the flying object R to a deployed position extended to the outer rear side of the flying object R, the flying object R and the wing bodies S are relatively provided with, as a mutual connection structure, a rotation shaft 1 and a guide groove 2 engaged with the rotation shaft 1 and permitting backward movement of the wing bodies S in the stored position, and the flying object R and the wing bodies S have cam mechanisms (4, 5) which rotate the wing bodies S to the outside of the flying object due to backward movement of the wing bodies S at the storage position, at mutual contact sections, in the wing-opening device, so that reliable wing-opening operation is possible with a simple structure, and cost reduction is achieved. <P>COPYRIGHT: (C)2013,JPO&INPIT |
