摘要	PURPOSE: To correct automatically temperature properties of magnetic bias force and magnetic breaking force by using a pair of permanent magnets placed so as to face same polarity through a spacer as detector mass. CONSTITUTION: Detector mass 34, which moves on a path 24 in an accelerometer 10 according to acceleration, is composed of a pair of permanent magnets 36 facing same polarity through a spacer with permeability and smaller diameter than that of the permanent magnet 36. When determining acceleration, the detector mass 34 in this structure cancels out temperature properties of magnetic bias force and magnetic breaking force, so that the temperature properties are automatically corrected with a simple structure.
