PROBLEM TO BE SOLVED: To provide an elevator seismic sensor capable of easily performing setting of earthquake control operation corresponding to the structure of a building. SOLUTION: The seismic sensor 8 is provided with a control arithmetic unit 11A comprising a triaxial accelerometer for detecting acceleration of each of X-, Y- and Z-axes, converting the acceleration detected by the triaxial accelerometer to an acceleration value with respect to each predetermined time and outputting the acceleration value; and with a storage device for storing set values corresponding to operation acceleration values of at least the X-axis and Y-axis for making an elevator in a building A, B perform earthquake control operation. The X-axis and Y-axis of the seismic sensor 8 are made to correspond to the width and depth directions of the building A, B. COPYRIGHT: (C)2009,JPO&INPIT
