A seat device 5 of the invention includes a plurality of springs 73 that are stretched in parallel over an opening of a frame 72, a cushion pad 60 that is placed above the springs, members 72C and 72D that do not move in synchronization with the displacement of the cushion pad 60 caused by a sitting operation, and a pressure sensitive switch SW1 that is disposed below the cushion pad 60 while having a gap with respect to a lower surface of the cushion pad. One switch element 12 that forms the switch in the pressure sensitive switch SW1 is supported by the members 72C and 72D, and the other switch element 22 that forms the switch is disposed between the one switch element 12 and the cushion pad 60 so as to be displaced toward the one switch element. |
