Abstract: In a configuration in which a holder holding a controller is mounted on a seat part with a plate-shaped member, the exposure of the mounting part of the plate-shaped member on which the holder is mounted is eliminated. A seat device includes a pressure sensor measuring a value relating to the seated person's state, a vibration imparting device performing a vibration imparting operation, an ECU controlling the vibration imparting device corresponding to the measurement result of the pressure sensor, a holder holding the ECU, and a mounting bracket fixed to a lower frame such that the holder is mounted on the lower frame of a seat part. The mounting bracket includes a mounting projection on which side wall of the holder is mounted in a predetermined mounting direction. When the side wall is mounted on the mounting projection, the mounting projection is covered with the side wall.

Abstract: Bioinformation of a seated person is more accurately measured. A heartbeat measurement device for measuring heartbeat of a person seated on a vehicle seat has heartbeat sensors and a circuit substrate: the heartbeat sensors have leading wires which output electric signals corresponding to a heartbeat and constitute a transmission path for the electric signals; and the circuit substrate has input terminals which receives the electric signals output from the heartbeat sensors, and a differential amplifier which amplifies the electric signals input to the input terminals. The heartbeat sensors and the circuit substrate are disposed in positions adjacent to each other in the vehicle seat, and terminal portions of the leading wires come out from portions adjacent to the circuit board of the heartbeat sensors are connected to the input terminals in a state abutting the input terminals.
