Abstract: PURPOSE:To detect stable pitot pressure by fitting a pitot tube so that a detection hole is under the oil level of oil remaining locally at the lower part in a pitot chamber during a stop of rotation without fail. CONSTITUTION:When the rotation of the rotation signal detector 56 is stopped, the detection hole 114a is undsr the oil level and blocked with the oil because of the fitting state of the pitot tube 114 to prevent the entry of air.
