In a detecting device main body 29 of a bending angle detecting device, a pin shaft 35 having a first engagement member 39 is normally biased upward by a first spring 41 in an approximately center position of a groove portion of a die D. In the detecting device main body 29, a rotor supporting member 47 having second engagement members 61 and 63 is normally biased by two second elastic bodies 49 having weaker biasing force smaller than that of the first spring 41. Two rotors 51 are positioned and borne to both sides of a groove widthwise direction of the die D at the upper portion of the rotor supporting member 47. A forward end of the pin shaft 35 is stopped in a lower position than the upper surface of the die by rotatively link members 43 which are engaged with the first engagement member 39 and second engagement members 61 and 63, and the two rotors 51 are positioned below the upper surface of the die. <IMAGE> |
