PROBLEM TO BE SOLVED: To resolve defects occurring when revolving and send flying a bamboo dragon fly (a T-shaped bamboo flying toy) such as a broken axis or a disturbance of flight posture caused by using a string and a tube for significantly increasing the number of revolutions or the speed of casting it on than when revolving the bamboo dragon fly by both hands. SOLUTION: These defects can be resolved by pulling the string in parallel and in a straightly downward direction from the tube instead of pulling the string diagonally. When pulled in parallel direction the end of the string drastically frogs a fist that grasps the tube. Thus in order to avoid this the string that run through a guide should be pulled diagonally so that it is pulled away from the fist and the guide is provided near the fist grasping the tube to stabilize the direction of the tube.
