PURPOSE:To improve the rate of magnifying displacement and to improve the linearity of the displacement with respect to pushing length by forming easily bendable hinge parts to the boundary part between the central position where a displacement body is mounted and arm parts and forming the arm parts into rigid construction thereby constructing the titled arm in such a way that force is exerted to both ends. CONSTITUTION:A buckling arm 11 is formed by providing a position 11a where the displacement body is mounted to the central part of a rigid belt-like body (stainless steel sheet, etc.), the arm parts 11b on both sides thereof and holding parts 11c to both ends and bending said body into an inverted V shape. Notched grooves 12 are formed between the position 11a and the arm parts 11b and between the arm parts 11b and the holding parts 11c from one side to form the easily bendable hinge parts 13, 14. When the arm 11 is pushed from both ends, the arm parts 11b move while maintaining the linearity and the position 11a moves linearly with respect to the pushing length. The rate of magnifying the displacement is thus improved. |
