<p><P>PROBLEM TO BE SOLVED: To improve detection precision of a load sensor in an operation device where the load sensor, set at rotation link section, electrically detects operation force based on the relative displacement between a main body member and an axial member. <P>SOLUTION: A transmission link 60 is disposed to be turnable at an operating pedal 16 through a connection pin 62, and while the circular member 34 of a load sensor 64 is integrally fixed at the transmission link 60, an axial member 36 is connected to an operating rod 22 through a clevis pin 26. Therefore, when the operating pedal 16 is made to press for operating, the transmission link 60 is relatively turned around the connection pin 62 based on the reaction force applied from the clevis pin 26 to the load sensor 64. So that, the relative displacement direction between the axial member 36 and the circular member 34 of the load sensor 64, namely, the displacement place of the deformation member 32 is substantially kept constant to improve the detection precision of the load sensor 64. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
