Claims

[Scope of utility model registration request]

A clamp locking part bent at a substantially right angle is fixed to the inner surface of the L-shaped flange attached to the damper case so that its upper end is approximately in the same position as the outer circumference of the L-shaped flange, and The end of the duct is bent at right angles, and widened parts are formed on the outer periphery of the bent flange to protrude in a direction opposite to the flange surface, and furthermore, the widened part when the L-shaped flange and the bent flange are brought into contact with each other. and a crowning part having approximately the same width as the combined width of the clamp locking part, a bent part formed by bending along one end in the longitudinal direction, and a flange formed by bending along the other end in the longitudinal direction. The clamp locking part and widened part of the L-shaped flange and the bent flange are firmly fixed by the crowning part of the clamp, and further clamped by the bent part and the flange introducing part. A damper case and duct connection structure characterized by connecting the damper case and the duct.
