Abstract: Two light-emitting units are to be prevented from overlapping each other in an image obtained through a camera. A tracked unit (30) has a first outer surface (A1) provided with a first light-emitting unit (H1), a second outer surface (A2) provided with a second light-emitting unit (H2), and a light shield portion (B). The second outer surface (A2) faces a second direction different from that of the first outer surface (A1). The light shield portion (B) is located further outside than the first light-emitting unit (H1) and the second light-emitting unit (H2).

Abstract: A forced flue heater draws out combustion gas using a burner fan installed downstream from a heat exchanger to prevent a burner fan motor from being heated to high temperature. The forced flue heater blows air to an air channel using a blower fan, and warms the air using the heat exchanger contained in the air channel. The pressure upstream from the heat exchanger is higher by a value corresponding to the resistance of the heat exchanger. The blower fan contained in an outer case draws in the surrounding air to lower the pressure inside the outer case. A partition separating between the inside and the outside of the air channel has an air outlet located upstream from the heat exchanger. This allows the cool air upstream from the heat exchanger to flow outside the partition. The air is then used as cooling air for cooling the burner fan motor. This structure prevents the burner fan motor from being heated to high temperature when the burner fan is heated to high temperature.
