CORNER REFLECTOR AND MANUFACTURE METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide means for improving form accuracy of an annular balloon in a corner reflector comprising the annular balloon of which the expansion amount is restricted by a restriction cloth.SOLUTION: A corner reflector 10 comprises: annular balloons 3a, 3b and 3c which are expanded in an annular shape when a gas is supplied to the inside; and a radio wave reflection film 5 that is expanded into a plane by expanding the annular balloons. The three annular balloons 3a, 3b and 3c are provided to be orthogonal with each other during expansion. A restriction cloth 7 is provided which is wound around each of the annular balloons. The restriction cloth 7 includes: an inner peripheral side cloth portion 7a which is positioned closer to a virtual center axis C of the annular balloon and extends in an annular direction around the virtual center axis C; and an outer peripheral side cloth portion 7b which is positioned oppositely to the virtual center axis C and extends in the annular direction. An extension degree of the outer peripheral side cloth portion 7b in the annular direction is greater than an extension degree of the inner peripheral side cloth portion 7a in the annular direction.SELECTED DRAWING: Figure 4
