The present invention provides a pressure measuring component unit, which can prevent damage when a rotation load becomes larger due to an object to be measured, wherein the pressure measuring component unit (2) is provided with a body case (3), a component body (11) and strain gages (14a-14f, 15a-15f) fixed on three connection bridges (11c) of the component body, on the fixed plate (17) fixed on the component body there is provided a metal ball (12), a pressure measuring component base (13) equipped with the component body is fixed on a body base (5), a bottom plate (25) is fixedly provided with a maintaining rod (26), the metal ball is provided with a top plate (31) connected with the bottom plate, and the top plate is connected with the fixed plate through spiral springs (43, 44). If the rotation load exerted on the maintaining rod becomes larger, the spiral springs are stretched to allow the top plate to rotate relative to the top plate. |
