Abstract

Le dispositif d'indication de sensibilité tactile (9) de l'invention est équipé : d'un boîtier (90) qui possède une paroi face (90F) de forme sensiblement plane; d'un élément couvercle (91) sur lequel est fixé un pavé tactile (97) à plat; et d'actionneurs piézoélectriques (10A, 10B). Des plaques de support (911A, 911B, 911C, 912A, 912B, 912C), sont placées sur l'élément couvercle (91) de sorte que la direction du côté court de l'élément couvercle (91) et du boîtier (90), et la direction de l'épaisseur de chacune des plaques de support concordent. Les plaques de support (911A, 911B, 911C, 912A, 912B, 912C) sont fixées au boîtier (90) à l'aide de trous débouchant (921A, 921B, 921C, 922A, 922B, 922C) formés à proximité d'une partie extrémité côté opposé à une partie extrémité connectée à l'élément couvercle (91). Les actionneurs piézoélectriques (10A, 10B) confèrent à l'élément couvercle (91) des vibrations dans ladite direction du côté court.
