To provide a load sensor with which, when unbalanced load acts upon a plane that receives a load, it is possible to detect a load in a direction orthogonal to the plane that receives the load with good accuracy.SOLUTION: Provided is a load sensor comprising: a housing 71 that has a load plane 714a that receives a load and is deformed due to the fact that the load plane receives the load; a strain detection unit 72 which, when the housing is deformed by the load that the load plane receives, detects a first strain amount that represents the strain amount in a first direction DRx of a plurality of regions in the housing and a second strain amount which is the strain amount in a second direction DRy of the plurality of regions in the housing; and a load computation unit 722 for calculating a surface orthogonal load Fz that the load plane receives and that acts in a third direction DRz that intersects the load plane, on the basis of the first strain amount in the plurality of regions and the second strain amount in the plurality of regions that are detected by the strain detection unit.SELECTED DRAWING: Figure 6
【課題】荷重を受ける面に偏荷重がかかる場合、荷重を受ける面に直交する方向の荷重を精度良く検出可能な荷重センサを提供すること。【解決手段】荷重を受ける荷重面714aを有し、荷重面が荷重を受けることによって変形する筐体71と、荷重面に受ける荷重によって筐体が変形する際に、筐体における複数の部位の第1方向DRxの歪み量である第1歪み量および筐体における複数の部位の第2方向DRyの歪み量である第2歪み量を検出する歪み検出部72と、歪み検出部が検出する複数の部位の第1歪み量とおよび複数の部位の第2歪み量に基づいて、荷重面が受ける荷重のうち、荷重面に交差する第3方向DRzにかかる面直交荷重Fzを求める荷重演算部722と、を備えた荷重センサ。【選択図】図6
