2. Description of the Related Art As is well known, a register of a vehicle is mounted on the vehicle as a device for ejecting air into the vehicle compartment, has a retainer connected to a duct for blowing air, and a front portion of the retainer is provided. A bezel as a design case is mounted while being arranged for mounting in a vehicle. The air blown into the retainer is blown with its wind direction adjusted vertically and horizontally by a plurality of adjusting blades (front blade or rear blade) 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 a damper which is arranged to be openable and closable for blowing 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, if the registers are arranged on both sides of the instrument panel, the operation dial is mounted on the side or the lower part of the register and is connected to the damper via the connecting mechanism.

For example, the conventional opening / closing device of the register 40 shown in FIG. 6 is provided with a retainer 41 and a bezel (not shown) which is locked to the front part of the retainer 41, and an operation dial 43 arranged on the bottom surface of the retainer 41. By connecting a damper (not shown), which is swingably arranged at the rear portion of the retainer 41, with a lever portion 43a extended to the operation dial 43 and a rotation lever 45 for rotating the damper, the operation dial 43 is connected. It was configured to open and close the damper when rotating. A long groove 45a is formed in the rotation lever 45 in the longitudinal direction, and a connecting shaft 43b formed on the side of the operation dial 43 movably arranged on the long groove 45a is formed.
The lever portion 43a of the operation dial 43 is pivotally supported and the long groove 45
It is inserted in a.

Therefore, when the lever portion 43a is swung by the turning of the operation dial 43, the connecting shaft 43b turns the turning lever 45 while moving on the long groove 45a of the turning lever 45. This allows the damper to be opened and closed.

In this type of register 40, a front blade for adjusting the air flow direction is supported by a bezel and arranged in a plurality in the horizontal direction, and a rear blade is supported in a retainer 41 and arranged in a plurality in the vertical direction. It is arranged.

[0007]

However, in the conventional operation dial 43, the operation dial 43 is used when the damper is closed.
Although the damper can be opened and closed by rotating the, it is not configured to be locked at the end of rotation, so even if the damper is closed, the damper remains stopped at that point. It is not possible to confirm that it is in a state. In other words, even if the damper is closed, the closed damper may open due to the strength of the air flow, and it is difficult to confirm the rotation end position of the operation dial 43. In some cases, the damper may be stopped before it reaches the final position of the damper, and there is a risk that the damper will be in a blown state without being closed in the retainer 41.

The present invention is to solve the above-mentioned problems, and in a register of a type in which an operation dial is mounted on a side portion or a lower portion of the register, when the damper is closed, it is reliably locked at the closed position of the damper. It is an object of the present invention to provide an opening / closing device for a damper in a register that can confirm that the damper is locked.

[0009]

That is, according to the first aspect of the invention, a damper for opening / closing the air blown into the vehicle compartment and an operation dial for operating the opening / closing of the damper are provided, and the damper and the operation dial are connected by a connecting mechanism portion, and the operation is performed. The dial is an opening / closing device for a damper in a register that is rotatably supported by a retainer that forms a ventilation passage and that is arranged at a side portion or a lower portion of the retainer, and that the operation dial is provided when the damper is closed. Fastening means for setting the lock position of the is arranged between the operation dial and the retainer, the fastening means, a claw portion formed on a lever portion extending to the damper side of the operation dial, A boss portion protruding from the retainer, wherein the operation dial is locked by engaging the claw portion with the boss portion. Than it is.

According to the present invention, when the damper is closed to stop blowing air into the vehicle compartment, the damper is closed via the connecting mechanism by rotating the operation dial in one direction. At this time, the claw portion formed on the lever portion interferes with the boss portion protruding from the retainer. And
When the claw portion interferes with the boss portion, the claw portion slightly bends and gets over the boss portion to engage with the boss portion. Therefore, when the operation dial reaches the rotation end position,
Since the operation dial can be locked by the fastening means composed of the claw portion and the boss portion arranged between the operation dial and the retainer, the damper connected to the operation dial maintains the stopped state in the closed position. Therefore, the damper can be surely closed. Moreover, by disposing the fastening means, when the operation dial is operated, the end position of the operation dial can be sensed by hand, so that the completion of the operation can be easily understood.

Further, in the damper opening / closing device of the invention according to the second aspect of the present invention, since the pair of the fastening means is provided at both ends of the rotation end position of the operation dial, the instrument panel of the vehicle is equipped with the fastening means. It can be used as a dual-purpose even when it is attached to both the left and right sides.
