Abstract
Provided is a mass sensor including a four-corner-adjusting-mechanism capable of reducing the sensitivity of four-corner adjustment without reducing the rigidity of a Roberval mechanism. A mass sensor () includes a Roberval mechanism () in which a floating frame () and a fixing frame () are connected by upper and lower sub-frames () having thin portions () formed thereon, and a four-corner-adjusting-mechanism () to perform parallelism adjustment. The four-corner-adjusting-mechanism () includes an adjusting screw (), and an upper elastic member () and a lower elastic member () disposed in series in the vertical direction so as to sandwich the sub-frame () to be subjected to parallelism adjustment.
