<p>PURPOSE:To inexpensively and certainly prevent a malfunction by providing detectors of different systems which can discriminate three states of 'no torque', 'right turning torque', and 'left turning torque' as torque detectors which give ordinary electric outputs. CONSTITUTION:The 2nd detector is fixed onto a fitting member 25 and composed of an intermediate contact 24 extended in the radial direction of an input shaft 1 and spring contacts 22 and 23 which are fixed onto a base board 21 and extended so as to put the front end section of the contact 24 between them. The contact 24 is displaced in the same direction as that, in which the shaft 1 is displaced,and separated from the contacts 22 and 23. Therefore, three states of a 'no torque' or 'minor torque' state where the contact 24 is contacted with the contacts 22 and 23, 'right turning torque inputted' state where the contact 24 is contacted with either one of the contacts 22 and 23, and 'left turning torque inputted' state where the contact 24 is contacted with the other one of the contacts 22 and 23, can be detected. Therefore, inexpensive and certain prevention of malfunctions can be realized.</p> |
