測定センサ構造。 Opposed circular portions are formed in the centers of the upper case and the lower case, one end of which is fitted onto a common shaft, and piezoelectric element units of the same shape are arranged facing each other in the circular portions. A fuel injection pipe having a larger diameter is fitted into the piezoelectric element unit, and the other ends of both cases are pressed and rotated about an axis to bring the piezoelectric element unit and the fuel injection pipe into close contact with each other. A sensor structure for measuring internal pressure of a fuel injection pipe, characterized in that a shaft or another shaft for rotating both cases around this shaft is a flexible structure.
