Abstract: The reflection portion 20 of the reflection member 1 is moved along the inner surface in the hole of the pipe W from the entrance opening of the hole of the pipe W to the exit opening of the hole thereof. In this case, the reflection portion 20 is guided by the guide portion 30 provided at both sides of the reflection portion 20. The shots, which are projected toward the inner surface in the hole of the pipe W, reach the reflection portion 20 through the holes of the guide portion 30 of the entrance side, and they are reflected toward the inner surface in the hole of the pipe W. Since the shots can be reflected toward the inner surface inside in the hole of the pipe W, the tendency that shots may be moved toward the inner surface outside in the hole of the curved portion P can be small. Therefore, since thinning of the wall of the pipe W can be performed, the pipe W can be strong, and the weight reduction of the pipe W can be simultaneously performed. As a result, the workability and the versatility can be improved, and the reflection member 1 can be easily used on the inner surface in the hole of the pipe having the curved portion.

Abstract translation: 反射构件1的反射部20沿管W的孔的内表面从管W的孔的入口向其孔的出口开口移动。 在这种情况下，反射部20被设置在反射部20的两侧的引导部30引导。向管W的孔内的内表面突出的射击通过该反射部20到达反射部20 入口侧的引导部分30的孔，并且它们朝向管W的孔中的内表面反射。由于可以在管W的孔内向内表面反射镜头，所以发射的趋势 可以在弯曲部分P的孔内向内表面移动可以很小。 因此，由于可以进行管道壁的变薄，所以能够使配管W牢固，能够同时进行配管W的重量减轻。 结果，可以提高可加工性和多功能性，并且可以容易地将反射构件1用于具有弯曲部分的管的孔中的内表面。
