ABSTRACT:
An acceleration detector comprising a housing defining a cavity therein and including a metallic bushing and a resinous outer case. An acceleration transducer assembly is disposed on the bushing in the cavity, and a resilient filler material is applied around the acceleration transducer assembly for resiliently sealing the acceleration transducer assembly from the exterior. The resilient filler material is sufficiently resilient to allow the movement of the inertial weight relative to the housing when an acceleration is applied to the inertial weight. The metallic bushing and the resinous outer case are integrally attached together by insert-molding so that they become an integral structure.
