The engaging groove engaging with the shaft is formed between the engaging groove and the protruding portion provided on one side of the operating lever.

e. Action When the operating lever slides along the horizontal fin, the arm engaged with the operating lever via the shaft moves, and the vertical fin provided with this arm rotates to change its direction. Since the vertical fins interlock with each other, all the vertical fins change their orientations accordingly.

f. Embodiment Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

In FIGS. 1 to 6, reference numeral 1 denotes a ventilator grill attached to a cold / hot air outlet of an air conditioner of an automobile. The ventilator grill 1 includes a ventilator case 2 attached to the air outlet and the ventilator case 2.
The louver body 3 is rotatably supported in the vertical direction.

The louver body 3 is formed by integrally forming the horizontal fins 4 in order to integrally rotate the plurality of horizontal fins 4.
A plurality of vertical fins 5 are rotatably supported on the upper and lower parts of the louver body 3 at the rear of the. The vertical fins 5 are pivotally supported on the rear side by a common connector 6 and interlock with each other.

Reference numeral 7 denotes an operation lever mounted on one of the horizontal fins 4 so as to be slidable along the axial direction of the horizontal fin 4 '. The operation lever 7 has upper and lower plates 7 as shown in FIGS.
It is a U-shaped member in which the upper and lower surfaces of the horizontal fin 4'are held by a and 7b. The lower plate 7b of the operating lever 7 has a protrusion 8 on the plate surface, which engages with the rear edge of the horizontal fin 4 '.
A protruding portion 7c is provided on one side surface, and an engagement groove 9 is provided between the protruding portion 7c and the protruding portion 7c. The vertical shaft 10 that engages with the engaging groove 9 is shown in FIG.
As shown in (b) and (c), it is projected on the upper surface of the arm 11 which is integrally provided on one of the vertical fins 5. The arm 11 provided on the vertical fin 5 ′ extends obliquely forward of the vertical fin 5 ′ in the basic position. This vertical fin 5 '
A notch 12 is provided in the front portion of the control lever 7 at a position corresponding to the plate 7b of the operation lever 7 for allowing the plate 7b to pass therethrough.

According to the above configuration, when the operation lever 7 is held and operated up and down, the louver body 3 rotates up and down and the lateral fins 4 move up and down. Next, when the operating lever 7 is slid laterally, the operating lever 7 slides along the horizontal fins 4 ',
The shaft 10 provided on the arm 11 of the vertical fin 5'is moved through the engagement groove 9. In this way, the shaft 10 rotates and moves laterally, changing the orientation of the vertical fins 5'to lateral direction. Since the vertical fins 5'and the other vertical fins 5 are connected by the connector 6, the vertical fins 5'and the other vertical fins 5 also change their orientation. The horizontal fins 4'and the vertical fins 5'include engagement grooves 9
Since they are engaged with each other via the arm 11 at positions displaced laterally, the distance between the horizontal fins 4'and the vertical fins 5'can be shortened. Further, since the operating lever 7 is located at the center in the width direction when the vertical fins 5'are in the basic position, there is no sense of discomfort.
