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. ## Claims ### Claim 1 A seat device comprising: a seat part on which a seated person is seated; and a vibration imparting device configured to impart vibrations to the seated person, wherein the seat part has a frame and a pad material disposed at an upper position of the frame, the pad material has a recessed part formed on the pad material, the vibration imparting device is disposed at a position facing the recessed part in a thickness direction of the pad material, the seat part has an overhang portion formed on a front end portion of the seat part, the vibration imparting device is disposed at a back position of the overhang portion, the pad material has a through hole that penetrates the pad material in the thickness direction of the pad material, and the vibration imparting device is disposed between the overhang portion and the through hole in a front to back direction of the seat part. ### Claim 2 (depends on 1) The seat device of claim 1, wherein the vibration imparting device is larger than the through hole in a front to back direction of the seat part. ### Claim 3 (depends on 1) The seat device of claim 1, wherein the vibration imparting device is supported by the frame, and the frame and the overhang portion are disposed at the same position in a vertical direction of the seat part. ### Claim 4 (depends on 1) The seat device of claim 1, wherein the pad material has a pad rear portion disposed at a back position of the vibration imparting device, and a vertical thickness of the vibration imparting device is smaller than a vertical thickness of the pad rear portion. ### Claim 5 (depends on 1) The seat device of claim 1, comprising a cover configured to cover the vibration imparting device from above, wherein the pad material has a pad rear portion disposed at a back position of the vibration imparting device, and a combined vertical thickness of the vibration imparting device and the cover is smaller than a vertical thickness of the pad rear portion. ### Claim 6 (depends on 1) The seat device of claim 1, wherein the vibration imparting device is formed of an unbalance mass type motor, and a rotating shaft of the unbalance mass type motor extends along a width direction of the seat part. ### Claim 7 A method for manufacturing a seat device, wherein the seat device has a seat part on which a seated person is seated and a vibration imparting device configured to impart vibrations to the seated person, the seat part has a frame, a pad material and an overhang portion, the pad material has a recessed part formed on the pad material, the method comprising: disposing the pad material at an upper position of the frame, and attaching the vibration imparting device to the seat part so that the vibration imparting device is disposed at a position facing the recessed part in a thickness direction of the pad material and is disposed at a back position of the overhang portion, wherein the pad material has a through hole that penetrates the pad material in the thickness direction of the pad material, and the vibration imparting device is disposed between the overhang portion and the through hole in a front to back direction of the seat part. ### Claim 8 (depends on 7) The method of claim 7, wherein the vibration imparting device is larger than the through hole in a front to back direction of the seat part. ### Claim 9 (depends on 7) The method of claim 7, wherein the vibration imparting device is supported by the frame, and the frame and the overhang portion are disposed at the same position in a vertical direction of the seat part. ### Claim 10 (depends on 7) The method of claim 7, wherein the pad material has a pad rear portion disposed at a back position of the vibration imparting device, and a vertical thickness of the vibration imparting device is smaller than a vertical thickness of the pad rear portion. ### Claim 11 (depends on 7) The method of claim 7, comprising a cover configured to cover the vibration imparting device from above, wherein the pad material has a pad rear portion disposed at a back position of the vibration imparting device, and a combined vertical thickness of the vibration imparting device and the cover is smaller than a vertical thickness of the pad rear portion. ### Claim 12 (depends on 7) The method of claim 7, wherein the vibration imparting device is formed of an unbalance mass type motor, and a rotating shaft of the unbalance mass type motor extends along a width direction of the seat part. ### Claim 13 A seat device comprising: a seat part on which a seated person is seated; and a vibration imparting device configured to impart vibrations to the seated person, wherein the seat part has a frame and a pad material disposed at an upper position of the frame, the pad material has a recessed part formed on the pad material, the vibration imparting device is disposed at a position facing the recessed part in a thickness direction of the pad material, the seat part has an overhang portion formed on a front end portion of the seat part, the vibration imparting device is disposed at a back position of the overhang portion, the pad material has a pad rear portion disposed at a back position of the vibration imparting device, and a vertical thickness of the vibration imparting device is smaller than a vertical thickness of the pad rear portion. ### Claim 14 (depends on 13) The seat device of claim 13, wherein the vibration imparting device is supported by the frame, and the frame and the overhang portion are disposed at the same position in a vertical direction of the seat part. ### Claim 15 (depends on 13) The seat device of claim 13, comprising a cover configured to cover the vibration imparting device from above, wherein the pad material has a pad rear portion disposed at a back position of the vibration imparting device, and a combined vertical thickness of the vibration imparting device and the cover is smaller than a vertical thickness of the pad rear portion. ### Claim 16 (depends on 13) The seat device of claim 13, wherein the vibration imparting device is formed of an unbalance mass type motor, and a rotating shaft of the unbalance mass type motor extends along a width direction of the seat part.
