The present invention relates to a heater fixing apparatus for fan heaters, and more specifically to an invention capable of absorbing the thermal deformation while firmly fixing a tubular heater shrank and expanded according to repeated heating and cooling. A fan heater (1) of the present invention comprises: a heater fixing means (10) to fix the position of a protection tube (4) surrounding a heater wire (3) onto a frame (7); a housing (5) surrounding various structures such as the heater wire (3) and the protection tube (4) including the frame (7); and a blower (6) which is placed on the upper part of one side of the housing (5) and forcefully inhales internal air and allows the inhaled air to pass through the heater wire (3) to be heated and supplied. The heater fixing means (10) comprises: a fixing hole (14) so as to be mounted on the frame (7) by bolts (12) and nuts (13); and a bracket (11) where a slide hole (15) is formed in a perpendicular direction to the fixing hole (14); and a silicone socket (20) which has a small-diameter part (21) made of a soft silicone material and shrink-fitted in the slide hole (15) of the bracket (11) and a large diameter part (22) having a fitting groove (23) to which the protection tube is fitted. |
