The ventilation passage in the blower chamber is formed across the full width of the blower chamber, and the blower chamber is formed with through-holes having a diameter smaller than that of the vent holes of the urethane pad and in a manner that the plurality of through-holes are overlapped with one vent hole in the urethane pad.
