PROBLEM TO BE SOLVED: To provide a load detector which can detect only a load applied to a sheet in a vertical direction with high accuracy and sensitivity in the case of application of a moment load.SOLUTION: First and second strain sensors 32, 33 are arranged in mutually adjacent two groove parts 31A, 31B formed in the central part of a columnar strain element 21, and from a difference between oscillation frequency of the first strain sensor and oscillation frequency of a second strain sensor, a shear load acting on the other end of the strain element in an axial direction is detected. |
