Abstract
The present invention provides a detection device for detecting a load and moment and capable of increasing the output by a strain gage. The detection device is provided with a characteristic sensor block. The sensor block includes a base having an axis extending in the direction of a load to be detected, a front side wall raised from the base at a position offset from the axis of the base, a rear side wall raised from the base at a position offset from the axis of the base in the direction opposite the front side wall, and an upper wall for connecting the upper end of the front side wall and the upper end of the rear side wall. The sensor block supports each strain gauge on the upper surface of the upper wall. The upper wall includes a center portion located at the center between the front side wall and the rear side wall, a first portion located between the center portion and the front side wall, and a second portion located between the center portion and the rear side wall. The first portion and the second portion, which support the strain gauges, have a smaller thickness than the center portion and are relatively easily deformed or strained.
