<p>A pair of scissor segments are connected at a rotation center to be mutually openable and closable. In the one scissor segment (1), a projection (5) has a stem portion (6) integrally formed on the inner surface of the rotation center. In the other scissor segment (2), a concave portion (8) is formed in the inner surface of the rotation center. The concave portion (8) are provided with an opening (9) allowing the projection to enter thereinto, and a stem supporting (12) portion rotatably supporting the stem portion (6) of the projection (5) entered into the opening (9). When both the scissor segments (1, 2) are connected to each other, the projection (5) is not usable on the outside surfaces of the scissor segments.</p> |
