To prevent an infrared ray heater from being cooled by wind and secure a sufficient quantity of far-infrared ray emission by installing an infrared heater, aux. heater and a fan in the sequence as named from the front of the structure, in a head casing whose front extremity is left open, and installing a baffle plate between the infrared heater and aux. heater.
An infrared ray therapeutic apparatus A has a head casing 1 in which an infrared heater 4, reflection board 5, aux. heater 7, and fan 8 are installed in the sequence as named from the front of the structure. A baffle plate 6 is installed on a ring-shaped stationary plate 17 for mounting the heater 4, and thereby the wind from the fan 8 is hindered from directly colliding with the rear central part of the heater 4. An aeration part 61 consisting of a plurality of micro-holes is installed near the peripheral edge of the baffle plate 6, and thereby the space Q bounded by the plate 6 and heater 4 is precluded from generation of a negative pressure. Thereby the wind from the fan 8 is sent through the gap D between the stationary plate 17 and baffle plate 6 to flow to the peripheral edge of the heater 4 so as to prevent directly colliding with the rear central part of the heater 4.
