Abstract

PROBLEM TO BE SOLVED: To smoothly attach/detach an air filter even when the height of a claw is diversified by the manufacturing lot by making a part of a claw body on a tip side in the inserting direction from a stopper thinner than a rest part. SOLUTION: When an air filter 4 is inserted into a casing from a lower side through an air filter guide port, an upper inclined surface 13b of a claw 13 is abutted on an inner surface of a side wall on a front panel side of the guide port and subjected to a force, and a part 12a above the stopper 14 of the claw body 12 is deflected to the other side wall side. A top part 13b of the claw 13 overrides an upper edge of the side wall to engage a lower inclined surface 13c with the upper edge of the side wall. Because the thickness t1 of the part 12a above the stopper 14 of the claw body 12 is smaller than the thickness to of the rest part 12b, a clearance δ1 is secured and the air filter 4 can be smoothly inserted. The lower inclined surface 13c is engaged with the upper edge of the side wall, and an upper inclined surface 14a is abutted on an inner surface of the side wall, and a cover covers the guide port.

As shown in FIG. 2 (b), when the user inserts the air filter 4 into the casing 1 from below through the air filter guide port 50, the upper slope 13a to the top 13b of the claw 13 is moved to the air filter guide port. The portion 12a of the claw body 12 above the stopper 14 contacts the inner surface 21a of the side wall 21 of the front panel 5 of the claw 50 and receives a force.
Bends toward the other side wall 22. Due to this bending, the top portion 13b of the claw 13 gets over the upper edge 21b of the side wall 21, and
As shown in (a), the lower slope 13c and the side wall 21 of the claw 13 are
The upper edge 21b is engaged. At this time, since the thickness t 1 of the portion 12a of the claw body 12 above the stopper 14 is made smaller than the thickness t 0 of the remaining portion 12b, the back surface 12c of the claw body 12 and the side wall 22 are not covered. A gap δ 1 with the edge 22b is secured. Therefore, the air filter 4 can be inserted smoothly. The lower slope 13c of the claw 13 and the upper edge 21b of the side wall 21 are engaged with each other, and the stopper 14
The upper sloped surface 14a contacts the inner surface 22a of the side wall 22, and the cover 42 covers the air filter guide port 50. The upper portion of the air filter 4 is guided along the air filter guide groove 51 (see FIG. 4) and is bent and curved rearward. In this way, the air filter 4 is attached to the casing 1.

When the air filter 4 is removed from the casing 1, the recess 43 provided in the cover 42 by the user.
Put a finger in (see FIG. 3) and pull the air filter 4 downward. Then, the lower slope 13c of the claw 13 is attached to the side wall 2
1 receives the force from the upper edge 21 b of the stopper 1 of the claw body 12
The portion above 4 is bent toward the side wall 22. Due to this bending, the top portion 13b of the claw 13 crosses over the upper edge 21b of the side wall 21, and the top portion 13b to the upper slope 13a of the claw 13 becomes the inner surface 21a of the side wall 21 in the same manner as shown in FIG. 2B. It comes into contact. At this time, the thickness t 1 of the portion 12a of the claw body 12 above the stopper 14 is made thinner than the thickness t 0 of the remaining portion 12b.
2 between the back surface 12c and the upper edge 22b of the side wall 22
1 is secured. Therefore, the air filter 4 can be pulled out smoothly. After this, the air filter 4 is pulled out with almost no resistance and is removed from the casing 1.

When riding over b, a gap δ 1 is secured between the back surface 12c of the pawl body 12 and the upper edge 22b of the side wall 22. Therefore, the side walls 21, 22 forming the air filter guide port 50
Even if the distance between and the height of the claw 13 of the air filter 4 varies depending on the manufacturing lot, the air filter 4 can be smoothly attached and detached.

Since the thickness of the portion 12b of the pawl main body 12 where the stopper 14 is provided is set to the same thickness t 0 as the thickness of the frame 40, the mechanical strength of the pawl main body 12 is actually reduced. The decrease in strength does not pose a problem.

As is apparent from the above, in the air filter mounting structure according to the first aspect of the present invention, the thickness of the portion of the main body of the pawl that is closer to the tip side in the insertion direction than the stopper is smaller than the thickness of the remaining portion. Therefore, when the top of the claw crosses over the back side edge of one side wall of the air filter guide port, a gap can be secured between the claw body and the back side edge of the other side wall of the air filter guide port. . Therefore, even if the distance between the side walls forming the air filter guide opening and the height of the claws of the engaging portion of the air filter vary depending on the manufacturing lot, the air filter can be smoothly attached and detached.
