One scissor piece constituting the pair of the scissor pieces has stoppers 15, 16 comprising engaging parts 15a, 16a for regulating a maximum opening angle of the pair of the scissor pieces by engaging the other scissor piece and support parts 15b, 16b for fixing the engaging part on one scissor piece.
