ロツトルバルブ開度検出装置。 The throttle valve opening sensor detects the opening of the throttle valve installed in the intake passage of the internal combustion engine, and the throttle valve opening value is stored as the fully closed position of the throttle valve using a fully closed switch. means for updating the value to a value corrected to the value detected by the throttle valve opening sensor at that time each time the upper limit of the fully closed position is determined based on a predetermined condition; and storing the detected throttle valve opening. Throttle valve fully closed position detection means for detecting the fully closed position of the throttle valve by comparing the throttle valve opening degree determined by the throttle valve opening and determining that the former value is less than or equal to the latter value. A throttle valve opening detection device characterized by:
