2. Description of the Related Art In recent years, the engine room of a vehicle has a very small space for installing an air cleaner because various accessories are arranged and the engine room itself tends to be small. There are also restrictions. However, if the element of the air cleaner becomes clogged, it needs to be replaced, and a structure that can be replaced without removing the cover is required. As a technology to meet such a request, for example, Jihei 22-21587
As disclosed in Japanese Patent Application Laid-Open Publication No. H10-209, there is known a structure in which an air cleaner is mounted laterally in an engine room for a vehicle and a cover is opened and closed right and left.

[0003] The air cleaner disclosed in this publication is
The structure is such that the flange portion of the element is directly held between the engagement surfaces of the case body and the cover. The air cleaner having this configuration has an advantage that the attachment / detachment of the element can be performed only by opening and closing the cover to the left and right without removing the element from the case body. However, there are actually technical problems described below.

[0004]

That is, in the above-mentioned publication, the cover is opened and closed to the left and right to replace the element and to seal the element. However, the cover is opened and closed due to the limitation of the mounting space of the air cleaner. There is a problem that a useless space is required for the operation.

The present invention solves the above-mentioned problems, and ensures the sealing of the element only by inserting a filter insert incorporating the element into the opening surface of the housing of the air cleaner, and at the same time, the mounting space is reduced. An object of the present invention is to provide an air cleaner that further reduces the amount.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a housing fixed to an engine room of a vehicle having an air intake portion and an exhaust portion, and is exchangeable in the housing. A filter insert inserted into the
An air cleaner having a filter element incorporated in the filter insert and having a gasket on four sides, wherein the filter element is incorporated in the filter insert such that the gasket is positioned around a surface of one side of the filter insert. A pair of inclined protrusions is formed at the lower part of the housing, and a pair of inclined recesses are formed in the lower part of the housing to be engaged with the protrusions, and the filter insert has an inclined protrusion formed on an upper side surface thereof. A surface portion, an engagement protrusion provided on the other side surface, and a pair of clips provided on an upper portion, an opening surface formed on an upper surface of the housing and capable of inserting and extracting a filter insert; The upper side surface of one of the surfaces has an inclined portion with which the inclined projecting surface portion engages, and the clip portion. And an engaging portion which engages with the gasket. When the filter insert is inserted from the opening surface to the closed position, the gasket is formed on the other of the opening surfaces. Is pressed against a sealing surface of the housing so that the filter insert is sealed to the housing.

[0007]

According to the above construction, when the filter insert is inserted from the opening of the housing and reaches the closed position, the pair of inclined projections at the lower portion of the filter insert are formed into the pair of inclined recesses. The gasket of the element incorporated in the filter insert is pressed against the sealing surface of the housing by fixing the sloping projection on the upper side of the filter insert to the sloping projection on the upper side of the housing. This improves the sealing performance.

And a discharge chamber 17 provided with

A rectangular filter insert 3 is shown in FIG.
An opening 18 into which the element 4 is inserted is formed as shown in FIG. 1B and FIGS. 1A and 1B. A lower portion 19 has a pair of inclined projections 20 and an upper portion 21. And a pair of clips 2 made of an elastic material such as spring steel provided on the upper surface 24.
5 is provided.

The element 4 is shown in FIG.
As shown in (a) and (b), a zigzag-filtered filter material 27 is held inside a rectangular parallelepiped outer frame 26, and rubber or the like is provided around the opening edge of the outer frame 26 on the suction chamber 6 side. A gasket 29 having a projecting surface 28 on the upper and lower surfaces of the element 4 is provided around the upper and lower surfaces of the element 4. When the outer frame 26 is inserted into the opening 18 of the filter insert 3, the projecting surface 28 It is configured so as to be positioned between the outer frame 26 and the outer frame 26. In addition, as shown in FIG. 1, the thickness of the gasket 29 is set to a thickness protruding from the filter insert 3 by only A.

In the above configuration, the element 4 shown in FIG. 2C is inserted into the opening 18 of the filter insert 3 shown in FIG. 2B, and the projecting surface 28 of the gasket 29 of the element 4 is inserted as shown in FIG. Is pushed into the filter insert 3 so as to be sandwiched between the outer frame 26 and the filter insert 3 to hold the element 4 in the filter insert 3.

Next, the filter insert 3 holding the element 4 is inserted through the opening 12 of the housing 2 as shown in FIG.
