<p><P>PROBLEM TO BE SOLVED: To improve detecting precision of a load sensor in an operating device which has in a rotating link section, the load sensor for electrically detecting an operating force, based on a relative displacement between a shaft-like member and a case member, and can detect the operating force transmitted via a linking pin. <P>SOLUTION: The case member 34 of the load sensor 30 has a pair of mounting wall portions 62a, 62b formed so as to be converged in a convex shape at a predetermined apex angleα, and the wall portions 62a, 62b are made to surface-contact a pair of rest surfaces 28a, 28b formed in a sensor-mounting hole 28 in a fixed and positioned state. Thus, even if the direction of an input load (reactive force), applied to a clevis pin 26 varies by stepping down on an operating pedal 16, the pair of rest surfaces 28a, 28b always bear the input load via the pair of wall portions 62a, 62b. This suppresses the case member 34 from flexure deforming due to stress concentration. As a result, positional displacement of the sensor is prevented, regardless of the variation in the direction of the input load, improving the detection accuracy. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
