When an object is accidentally covered on the main body 31 so as to block the air inlet 46 or the main body 31 falls down during use of the futon dryer, the outside air is taken in from the air inlet 46. Therefore, there is a possibility that abnormal overheating of the main body 31 may be caused. In order to prevent this overheating, an over-temperature prevention device 40 is provided on the wall surface of the heater case 39. However, since the heater case 39 is constantly exposed to a high temperature by the radiant heat of the heater 38, the over-temperature prevention device 40 is provided. The difference between the temperature of the heater case 39 in the normal case where the futon dryer is operating normally and the temperature of the heater case 39 in the case of abnormal operation with respect to the temperature at which 40 operates is difficult to understand. As a result, the overheating prevention device 40 operates to stop the operation of the futon dryer even though the futon dryer is operating normally, or vice versa. The operation of the preventive device 40 may be delayed, and the operation of the futon dryer may not be stopped immediately.
