Abstract

A damper device can easily and reliably lead bearing heater connected with a heater. In the air door device (1), the heater wire (8) through the formation of heater on the bulkhead plate (20) of the lead pathway (25) and pulled around to the driving chamber (60) side. And the heater wire (8) the middle part on the surface of the shell (3) of the housing (3) of the side plate portion (321) surface and formed on the bulkhead plate (20) the next plate side lead support department (26) is supported. Heater wire (8) along the bottom of the side plate (3) the Housing Department 321 outer surface (concavity (33) (330) along the X direction extension, the next plate side supporting leads the Ministry (26) for supporting a heater wire (8) along the side (321) outer surface extending part.

Description

technical field [0001] The present invention relates to a damper device used for cold air passages of refrigerators and the like. Background technique [0002] For a damper device used in a cold air passage of a refrigerator, for example, a structure in which a shutter is driven by a shutter driving mechanism to open and close an opening formed in a frame has been proposed (see Patent Documents 1 and 2). In addition, if the water condensed around the opening freezes, the frame and the flap are adsorbed by freezing, and the flap cannot be driven in the opening direction. Therefore, it has been proposed to provide a rectangular frame-shaped heater around the opening of the frame (see Patent Documents 1 and 2). [0003] Patent Document 1: Japanese Patent Application Laid-Open No. 7-19709 [0004] Patent document 2: Chinese utility model announcement number CN201973990U [0005] Like the damper devices described in Patent Documents 1 and 2, when a heater is installed, it is n...
