Claims

[Scope of utility model registration request]

A driven body 3 that moves together with the object to be measured
a weight 5 supported via a spring plate 4 in a space 1a formed inside the driven body 3; an oil 6 filled in the space 1a; A damper 7 absorbs the volume change of the oil due to the damper 7, and a damper 7 absorbs the distortion when the weight 5 is displaced relative to the driven body 3 and the spring plate 4 is distorted when acceleration is applied. 1. An acceleration sensor comprising a strain gauge for detecting, wherein the damper 7 receives the weight 5 when excessive acceleration is applied.
