Title: LOAD DETECTOR AND TENSION DETECTOR
Abstract:
A load detector (1) is provided with a pair of plate springs (21), a flange (10), a movable rigid body (23), a load support member (24), and a displacement sensor (30). The longitudinal direction of one plate spring (21c) is perpendicular to the direction of a load (L1) applied from a shaft (101). The other plate spring (21d) is parallel to said plate spring (21c) and is located at a distance from said plate spring (21c) in the direction of the load (L1). The flange (10) is mounted to a base, and one end (21a) of each of the pair of plate springs (21) is affixed to the flange (10). The movable rigid body (23) connects the other ends (21b) of the pair of plate springs (21). The load support member (24) is disposed between the pair of plate springs (21), is affixed to the movable rigid body (23), and has a bearing section (25) which receives the load (L1) from the shaft (101). The displacement sensor (30) detects the displacement of the movable rigid body (23) in the direction of the load (L1).
