When the hook 7 is inserted into and removed from the hook mounting portion 4, the tip of the hook 7 and the reinforcing rib 7a can smoothly move on the inclined surfaces c and d, and the movable lever 9 is elastically deformed accurately. It is configured to be able to do.

Further, a regulating means for regulating the suction grille 6 from rotating beyond a predetermined angle and a releasing means for releasing the regulating means are shown in FIG. 3A as a second embodiment. As shown in FIGS. 3A to 3C, a horizontal piece slidably held by front and rear guides 4a provided on both sides of the hook mounting portion 4 and a hanging piece hanging down from the front end thereof form an approximately L-shape. A movable lever 9 provided with a convex locking claw 9a on the horizontal piece, and a concave locking portion provided at the tip of the hook 7 corresponding to the locking claw 9a of the movable lever 9; When the suction grille 6 is rotated at a predetermined angle, the locking claws 9a are locked to the locking portions to restrict the suction grille 6 from rotating beyond a predetermined angle, When the suction grill 6 is rotated by a predetermined angle or more, the hanging piece is Pressing with a finger, the horizontal piece is slid backward by the guide 4a by elastic deformation of the substantially L-shaped portion, and the locking claw 9a is released from the locking portion, Thereby, the operation of rotating the suction grille 6 and the operation of attaching and detaching it to the front panel 3 can be clearly distinguished with a simple configuration, and when the suction grille 6 is rotated, The locking claw 9a is moved to the outside of the locus where the locking portion of the hook 7 moves only when the hanging piece is pressed by a finger, without being detached from the front panel 3 and suddenly dropping. Thus, the suction grill 6 can be removed by releasing the regulating means.

The locking claw 9a provided on the horizontal piece
The base end is formed to be thick and the front surface is provided with an inclined surface c ′, so that the locking claw 9a has the strength and when the locking claw 9a is moved, The configuration is such that the tip of the hook 7 does not contact the stop claw 9a.

Further, as a third embodiment, a restricting means for restricting the suction grille 6 from rotating beyond a predetermined angle and a releasing means for releasing the restricting means are shown in FIG. 4 (C), the rear end is connected to the bottom surface of the hook mounting portion 4 to form a substantially L-shaped horizontal piece and a vertical piece hanging down from the front end thereof. A movable lever 9 provided with a convex locking claw 9a on the horizontal piece; and a concave locking portion provided at the tip of the hook 7 corresponding to the locking claw 9a of the movable lever 9. When the suction grille 6 is rotated at a predetermined angle,
9a is locked to the locking portion to restrict the suction grill 6 from rotating beyond a predetermined angle, and when rotating the suction grill 6 beyond a predetermined angle, the horizontal piece is manually gripped. Press, and the locking claw 9a is released from the locking portion by elastic deformation of the movable lever 9;
Thus, the operation of rotating the suction grille 6 and the operation of attaching and detaching the suction grille to and from the front panel 3 can be clearly distinguished by a simple configuration.
When the arm is rotated, the hook does not drop off from the front panel 3 and suddenly falls. By moving the stop claw 9a, the regulating means is released and the suction grill 6 can be removed.

Also, a projection 9c is provided at the front of the vertical piece,
As shown by an arrow C in FIG. 4B, the movable lever 9 can be more accurately pressed by placing the finger on the same protrusion 9c and pressing it downward to elastically deform the movable lever 9. As a result, the operability is improved.

Further, since the vertical piece and the projection 9c are formed integrally with the movable lever 9, the dimensions and shape can be accurately finished and the structure is advantageous in terms of cost.

With the above configuration, FIGS.
(C), FIG. 2 (A) and FIG. 2 (B), and FIG. 3 (A)
As shown in FIG. 3 (C), FIG. 4 (A) and FIG. 4 (B), when the suction grill 6 is rotated, the hook 8 contacts the locking claw 9a and rotates. Since the angle is regulated, the major axis portion b of the support shaft 8 becomes larger than the insertion opening a of the bearing portion 5 so that the support shaft 8 does not come off the bearing portion 5. In addition, when the suction grille 6 is removed, the movable lever 9 is elastically deformed by further rotating the suction grille 6 to release the regulating means, and the short diameter portion b ′ of the support shaft 8 is Since it is smaller than the insertion opening a of the bearing 5, the grill attachment / detachment device of the air conditioner is configured so that the support shaft 8 can be easily detached from the bearing 5.
