2. Description of the Related Art As is well known, a vehicle register has a retainer mounted as an air ejecting device into a vehicle compartment and connected to a duct for blowing air. A bezel, which is arranged for mounting inside and serves as a design case, is attached. The air blown into the retainer is blown with its wind direction adjusted vertically and horizontally by a plurality of adjusting blades arranged near the outlet. As a result, it is possible to blow air according to the position desired by the occupant and give a comfortable feeling.

Further, at the rear of the retainer, there is provided an openable and closable damper for feeding air into the vehicle compartment. Usually, the damper is configured to be openable and closable by rotating an operation dial arranged on the bezel side of the register, and thus the register is provided with an opening / closing device for opening and closing the damper. On the other hand, the register is configured into various types by considering the design shape or the operating position of the register, and the mounting position of the operation dial is different depending on the structure of each register. For example, in the case of a register in which the width of the air outlet is relatively long, a center wall is provided at the center of the air outlet so that the air outlet is divided into two parts, and the center wall is supported. And the operation dial was arranged. Therefore, the opening / closing device of the damper has a different structure depending on each type of register.

For example, the conventional opening / closing device for a register 40 shown in FIG. 8 includes an operation dial 43 arranged on a central wall portion 42 of a bezel 41 and a damper 45 arranged on a rear portion of a retainer 44 so as to be swingable. By connecting with the connecting lever 46 and pivotally supporting the connecting lever 46 at each end,
The damper 45 can be opened and closed when the operation dial 43 is rotated. In the register 40 of this type, the front blade and the rear blade that adjust the blowing direction are configured as a barrel unit formed separately from the retainer 44 or the bezel 41, and are inserted in the vicinity of the blowing outlet of the retainer 44.

[0005]

However, in the conventional operation dial 43, when the damper 45 is closed, the damper 45 can be opened and closed by rotating the operation dial 43, but at the end of rotation, Since it is not configured to be locked, the damper 4
Even if 5 is closed, it cannot be confirmed that the damper 45 remains stopped at that time. In other words, even if the damper 45 is closed, depending on the strength of the air blow,
There is a possibility that the damper 45 that has been closed may be opened.
Further, since it is difficult to confirm the rotation end position of the operation dial 43, when the damper 45 is closed, the damper 45 may be stopped before reaching the final position of the damper 45, and the damper 45 is sealed in the retainer 44. There is a risk that the air will be blown without being closed.

The present invention is to solve the above-mentioned problems, and when closing the damper, it is possible to reliably lock the damper at the closed position, and to open / close the damper in the register. The purpose is to provide.

[0007]

The damper opening / closing device according to the present invention is configured as follows in order to solve the above problems. That is, according to the first aspect of the present invention, the damper opening / closing device is provided with a damper for opening / closing the air blown into the vehicle compartment, and the operation dial for operating the opening / closing of the damper is a damper opening / closing device in a register arranged at the center of the bezel. When the damper is closed, a fastening unit for setting a lock position of the operation dial is provided, and the fastening unit is a protrusion arranged on an outer peripheral surface of the operation dial,
An interference portion provided on an inner wall portion of the bezel that supports the operation dial is provided, and the operation dial is locked by engaging the projection portion and the interference portion. .

According to the present invention, when the damper is closed to stop the blowing of air into the vehicle compartment, the damper is closed by rotating the operation dial in one direction. When the operation dial reaches the rotation end position, the operation dial can be locked by the fastening means composed of the protrusion formed on the operation dial and the interference portion provided on the inner wall of the bezel. It is possible to maintain the stopped state of the damper in the closed position, and to reliably close the damper. Moreover,
When the operation dial is operated, the end position of the operation dial can be sensed by hand due to the engagement between the protrusion and the interference portion, so that the completion of the operation can be easily understood.

Further, since the interference portion is a boss portion formed integrally with the inner wall portion of the bezel, the boss portion is integrally formed with the bezel. Therefore, it is possible to provide a register which can be manufactured at low cost.
