Claims

[Scope of utility model registration request]

In a damper drive device that opens and closes a duct by rotating blades in a damper body provided in a duct using a pneumatic cylinder, a cylindrical case body is attached to the rotating shaft of the blade that protrudes outside the damper body. A notch hole is formed in the case body along the rotation direction thereof, and a drive ring member having a drive lever protruding from the notch hole and connected to the piston rod end of the pneumatic cylinder is fitted into the case body, and the drive ring member is fitted into the case body. An adjustment member having an adjustment handle attached to a portion protruding to the outside of the case body is fitted into the case body so as to be slidable in the axial direction thereof, and the case body is interlocked with the movement in the rotational direction. The adjusting member is locked against the drive ring member by its axial movement.
A removable damper opening adjustment device.
