Title:
OPENING AND CLOSING DEVICE
Document Type and Number:
Japanese Patent JP2526854
Kind Code:
B2
Abstract:
PURPOSE: To lessen operating force when each passing through hole is opened/ closed by providing the device with a movable membrane shaped member equipped with an opening section capable of opening each passing through hole, and with an operating means moving the membrane shaped member in a state that the aforesaid member is faced to each passing through hole, and concurrently raising the peripheral section of each passing through hole up to the membrane shaped member side.
CONSTITUTION: When a drive plate is driven by a wire so as to be moved, as a pinion 49 and a drive shaft are rotated, a ventilation blow-off port 13 is fully opened by a first opening section 25, and a defroster blow-off port 12 and a heater blow-off port 14 are entirely blocked by a film damper 20. Since each raised-up section 70 is formed at the peripheries of the respective blow-off ports 12 through 14, only each rasied-up section 70 comes in contact with the film damper 20 at the side of a case 11. This constitution allows frictional force to be lessened when the film damper 20 is moved, so that operating force can thereby be made small. Therefore, noise due to friction can also be made low.
