  • Inclination sensor
    Patent number: 7430809
    Abstract: Is disclosed an inclination sensor for detecting a tilted state of a case by detecting by a magnetic sensor a magnetized portion of a pendulum type movement mounted rotatably on a shaft in accordance with inclination of the case, wherein the shaft fitted with a clearance in a rotation shaft hole of the movement is further provided at both ends with loosely fitted thereon spacers and mounted in the case. This realizes non-restricted state of both the movement and the shaft. Thus, the movement obtains an improved response characteristic and an increased stability since no oscillation of a running vehicle is transmitted through the shaft to the movement.
    Type: Grant
