PROBLEM TO BE SOLVED: To provide an attitude control structure and a projection test device enabling to achieve size reduction of a projection test device and allowing a projection test with high reproducibility to be conducted at low cost while an attitude of a projected projectile is maintained.SOLUTION: An attitude control structure 31 for suppressing attitude change of a projected projectile 11 is provided with a guide rail 33 provided to surround a track X of the projectile 11 and forcing the track X while constraining the attitude of the projectile 11, and a support mechanism 35 for supporting the guide rail 33 movably in a dynamic radial direction so that an inner diameter of a part 34 surrounded by the guide rail 33 is variable. The support mechanism 35 is provided with a support frame 38 for bundling the guide rail 33, and a rod-like member 40 inserted in a telescopic manner toward the inside from the outside of the support frame 38, and having a front end 39 which is positioned inside of the support frame 38 and to which the guide rail 33 is attached. |
