Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an air cleaner device for a vehicle.
[0002]
[Prior art]
As an air cleaner device for a vehicle, there is known an apparatus in which an upper case and a lower case are joined to each other by a hinge so that the upper case can be opened and closed with respect to the lower case (see, for example, Japanese Patent Laid-Open No. 7-247923). ).
[0003]
[Problems to be solved by the invention]
Air cleaner devices for vehicles are constantly subject to vibration due to the location characteristics where they are used. The hinge shaft portion and the claw portion constituting the hinge are worn by the constant vibration and repeated opening and closing of the air cleaner case. For this reason, the tightness of the packing interposed between the cases is reduced, and the sealing property of the air cleaner case is lowered.
[0004]
SUMMARY OF THE INVENTION An object of the present invention is to provide an air cleaner device for a vehicle that can prevent a deterioration in airtightness of an air cleaner case due to wear of members constituting a hinge.

DETAILED DESCRIPTION OF THE INVENTION
5 and 6 show the appearance of an air cleaner device to which the present invention is applied. The air cleaner device has an upper case 1 and a lower case 2. These cases 1 and 2 are combined to be freely opened and closed by a pair of hinges H and H on one side. The other side portions of the cases 1 and 2 are constrained to each other via a pair of detachable clips C and C.
[0016]
FIG. 1 shows details of the hinge H. A pair of ribs 2b and 2b extending upward are formed on one side of the lower case 2 (only one rib 2b is shown in FIG. 1), and a hinge shaft 2a having a rectangular cross section is provided at the upper end of the ribs 2b and 2b. (See FIG. 4). One side of the upper case 1 is provided with a claw 1a projecting sideways. Prior to assembly of the cases 1 and 2, the filter element 3 is attached to the upper end of the lower case 2. A packing 4 is attached to the outer periphery of the filter element 3 over the entire periphery. When the upper case 1 is put on the packing 4 while the claw 1a of the upper case 1 is inserted into the insertion hole 2c below the hinge shaft 2a, the claw 1a pushes the packing 4 toward the lower case 2 and shows the periphery of the hinge shaft 2a. 1 counterclockwise. When the upper case 1 is completely covered on the lower case 2 and the cases 1 and 2 are fastened with the clip C in this state, the claw 1a pushes the packing 4 toward the lower case 2 by a predetermined amount, and the repulsive force against the claw 1a Is biased upward and pressed against the lower surface side of the hinge shaft 2a.
[0017]
In the hinge H as described above, when the hinge shaft 2a and the claw 1a are worn, the claw 1a escapes upward from the original position, that is, the position where the packing 4 is pushed by a specified amount, and the tightening allowance of the packing 4 is reduced accordingly. This may cause a seal failure. Therefore, in the illustrated cleaner device, the clip 5 as a protective member is attached to the hinge shaft 2a.
[0018]
The clip 5 is formed by bending a plate material made of an elastic material, for example, a metal such as stainless steel into a U-shaped cross section (see FIG. 3). A convex portion 5 a is formed on one side of the clip 5 toward the inside. A spring portion 5b swelled in an arc shape on the outer side is provided on the tip side of the convex portion 5a.
[0019]
As shown in FIGS. 1 and 4, the clip 5 is attached to the outer periphery of the hinge shaft 2 a from the inside of the lower case 2. As shown also in FIG. 2, the recessed part 2d is provided in the lower surface side (side which the nail | claw part 1a contacts) of the hinge axial part 2a. The clip 5 is attached to the hinge shaft 2a with the spring portion 5b facing downward, that is, toward the lower case 2, and the convex portion 5b fits into the concave portion 2d of the hinge shaft portion 2a. Thereby, the clip 5 is prevented from coming off from the hinge shaft portion 2a.
[0020]
According to the air cleaner device configured as described above, the claw portion 1a moves around the hinge shaft 2a while contacting the clip 5 when the upper case 1 is opened and closed. Therefore, there is no possibility that the hinge shaft 2a is worn. When the cases 1 and 2 are closed, the spring portion 5 b of the clip 5 presses the claw portion 1 a toward the lower case 2. For this reason, wear due to vibration is prevented, and even if wear occurs, a certain tightening allowance is obtained for the packing 4, and the sealing performance of the case does not deteriorate.
[0021]
The present invention is not limited to the above-described embodiment, and various modifications may be made. For example, a rubber material or the like can be applied to the protective member instead of the clip 5.
[0022]
【The invention's effect】
As described above, according to the air cleaner device for a vehicle of the present invention, it is possible to prevent the wear of the case due to vibration and the wear due to the friction of the hinge that is generated for opening and closing the case. For this reason, the air cleaner apparatus which does not reduce the sealing performance of a case by opening and closing or vibration is realizable.
