<P>PROBLEM TO BE SOLVED: To increase the usability of an integral damper without impairing the maintainability thereof by easily changing the range of the opening/closing angle thereof. <P>SOLUTION: In this damper device for a ventilation device, the projection part 8 of a damper plate 10 attached to a damper fixing plate 3 has a round hole 9, and a shaft 13 joins a cam 7 to the round hole 9. Therefore, the range of the opening/closing angle through which the damper plate 10 is opened can be optionally changed according to the position of the round hole 9 of the projection part 8 to cope with the size and the range of the opening and closing angle of the damper plate 10. Consequently, the usability of the integral damper can be increased without impairing the maintainability thereof. <P>COPYRIGHT: (C)2012,JPO&INPIT |
