ABSTRACT:
A strain gauge type sensor and a strain gauge type sensor unit using the sensor are improved in sensitivity. In a strain gauge type sensor1for measuring at least one of multiaxial force, moment, acceleration, and angular acceleration, externally applied, diaphragms15and16different in thickness are formed at inner and outer edges of a substantially disk-shaped interconnecting portion13interconnecting a vicinity of an upper end of a force receiving portion 11 and a fixed portion12disposed around the force receiving portion11. The thicknesses of the diaphragms15and16are determined such that strains at intersections of a straight line extending through an origin O with the diaphragms15and16are equal to each other. Strain gauges are disposed at the intersections of the straight line extending through the origin O with the diaphragms15and16.
