<p><P>PROBLEM TO BE SOLVED: To improve detection accuracy of a load sensor which electrically detects an operating force on the basis of relative displacements of a ring-like member and a shaft-like member and which is provided for a rotation connecting part in an operating apparatus capable of detecting an operating force transmitted via a connecting pin. <P>SOLUTION: A clevis pin (the connecting pin) 26 is inserted through a clearance hole 72 in such a way as to be relatively displaced to an operating pedal 16. A rotating link 68 is provided between a sensor pin 64 of the load sensor 30 and the clevis pin 26. Since a reaction force exerted on the load sensor 30 from the clevis pin 26 acts approximately in one fixed direction (approximately in the left direction in Fig.1(a)) at all times even if the operating pedal 16 and an operating rod 22 are relatively rotated on the axis of the clevis pin 26 with a treading operation of the operating pedal 16, it is possible to improve detection accuracy of the load sensor 30, reduce variations in detection accuracy, and achieve high reliability. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
