<P>PROBLEM TO BE SOLVED: To provide a movable louver with a simple structure for opening and closing a movable panel, in a ventilation louver mounted to a ventilation device body. <P>SOLUTION: The ventilation louver 13 includes: a louver frame 14 having an opening in the front and mounted to the ventilation device body; a movable lover 15 pivotally supported at a lower part of the louver frame 14 and covering the front of the louver frame 14; and a holding part 22 provided on the back of the movable louver 15 and making direct engagement with a hold release mechanism 24 provided at the louver frame 14. This configuration allows the movable louver 15 to be held at the holding part 22 thereof by the hole release mechanism 24 so that the ventilation louver 13 is closed, and the movable louver 15 to turn around a shaft support part serving as an axis by the self-weight of the movable louver 15 when the hold release mechanism 24 releases the hold so that the ventilation louver is opened, thus requiring no driving mechanism, and achieving a ventilation device with a simple structure for opening and closing the movable panel. <P>COPYRIGHT: (C)2013,JPO&INPIT |
