<P>PROBLEM TO BE SOLVED: To provide a vibration detection device capable of detecting a plurality of vibrations by devising an input form of external force on a strain sensor in order to realize control of a plurality of functions of a vehicular door. <P>SOLUTION: The vibration detection device comprises a piezoelectric body 1 for creating an electrical signal by having deformation caused by vibrations or the external force, an electrode plate 2 installing the piezoelectric body 1, and a support section 3 for supporting the electrode plate 2. The electrode plate 2 can detect the whole vibration transmitted from the support section 3, and a pushing means 10 for giving a plurality of kinds of pushing force respectively generating individual vibrations different from the whole vibration is provided. <P>COPYRIGHT: (C)2009,JPO&INPIT |
