Patent ID: 6877716

Claim:
A motor-operated damper device comprising: a baffle driving device equipped with a motor; a baffle that is driven by the baffle driving device; a frame defining an opening section that is closed and opened by the baffle, the opening section having a peripheral edge section; a buffer member that is attached to one of the baffle and the peripheral edge section of the opening section and that resiliently deforms and contacts an other of the baffle and the peripheral edge section of the opening section when the opening section is closed by the baffle, wherein the motor uses a detent torque thereof to maintain a stopping state at a first position in which the buffer member is resiliently deformed to provide a close contact with the other and in which the buffer member is capable of recovering its original shape; and a stopper that prevents the other from sinking into the buffer member past a second position beyond which the buffer member will be permanently deformed, wherein the motor has sufficient torque to cause the other to sink into the buffer member against a resilience of the buffer member to the second position.
