Since the bracket presses and supports the air cleaner from above, the load on the bracket can be small.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An engine air cleaner support structure of an embodiment of the present invention will be described below with reference to FIGS.
In the figure, an air cleaner 1 includes a case 2 and a cap 3
And the air cleaner element 4 is housed inside. A concave groove 12 extending from one end to the other end (from the left side to the right side in FIG. 2) is formed on the upper surface of the cap 3 of the air cleaner 1. The central portion of the recessed groove 12 is widened so that the width thereof becomes an arc, and an upper side grommet 13 described later can be accommodated therein.

A bracket 14 is inserted into the groove 12. The bracket 14 has a plate-shaped bracket main body 15 whose central portion is widened in an arc shape, and first and second mounting portions 16 formed by bending the bracket main body 15 at both ends thereof into a substantially L shape. , 17 and. The first mounting portion 16 is longer than the second mounting portion 17.

Air cleaner mounting portion 1 of engine room 9
A vehicle-body-side first support member 19 that holds the first mounting portion 16 is fixed to the member 8. The second mounting portion 1 is attached to the wall portion 20 provided perpendicularly to the air cleaner mounting portion 18.
The vehicle-body-side second support member 21 that holds 7 is fixed. The bracket 14 has the first and second brackets as described above.
The mounting parts 16 and 17 of the vehicle body side first and second support members 1
It is fixed to the engine room 9 by holding it in the engine compartments 9 and 21.

The tubular upper grommet 13 is interposed between the center of the bracket body 15 and the cap 3. The shape of the upper grommet 13 is not limited to the cylindrical shape, and may be a columnar shape, a polygonal columnar shape, or the like. Further, the number of upper side grommets 13 may be two or more.

An annular projection 22 is formed on the lower surface of the case 2. A grommet (hereinafter, referred to as a lower grommet) 23 is arranged so as to be located inside the annular projection 22, and the air cleaner 1 is provided with the air cleaner mounting portion 1.
8 is mounted via the lower grommet 23.

In the air cleaner support structure of this engine, the air cleaner 1 is placed on the air cleaner placing portion 18 via the lower grommet 23, and in this state, the bracket is fitted into the groove 12 of the cap 3 via the upper grommet 13. 14 and positions the first and second mounting portions 16 and 17 of the bracket 14 on the vehicle body side first and second support members 19 and 21.
The air cleaner 1 is supported in the engine room 9 by holding the air cleaner 1 by means of fixing with bolts.

Since the lower grommet 23 is interposed between the air cleaner 1 and the air cleaner 1, and the upper grommet 13 is interposed between the air cleaner 1 and the bracket 14, the vehicle body vibration is transmitted to the air cleaner 1. The lower side grommet 23 and the upper side grommet 13 suppress the movement.

In this engine air cleaner support structure, the air cleaner 1 is not disassembled (non-disassembled state).
Since the air cleaner 1 can be fixed to the engine room 9, there is no need to disassemble the air cleaner 1 and the subsequent assembling work, and the number of assembling steps can be reduced accordingly, and the product can be manufactured at low cost. .

7 and 8 or 9 and 10 described above.
In the prior art shown in (1), in order to prevent the vehicle body vibration from being transmitted to the air cleaner 1, the grommet 6 and the collar 7 are inserted into the bottom portion of the case 2 or a plurality of holes formed in the stay 10, respectively. It took a lot of time. On the other hand, in this embodiment, the lower grommet 23 is interposed between the air cleaner 1 and the air cleaner 1, and the upper grommet 13 is interposed between the air cleaner 1 and the bracket 14 to achieve the above function. As a result, the assembling property becomes excellent by this amount. Further, the plurality of grommets 6 and the collar 7 which have been conventionally required can be omitted, and the number of parts can be reduced accordingly, and the cost of the product can be reduced.

Further, the air cleaner 1 is supported without disassembling the air cleaner 1. Therefore, invasion of dust or the like that may occur during disassembly is not caused.

In the air cleaner support structure of the engine shown in FIGS. 9 and 10 described above, since a large load is applied to the stay 10, it is required that the stay 10 has excellent durability. On the other hand, in this embodiment, since the bracket 14 presses and supports the air cleaner 1 from the upper side, the load applied to the bracket 14 can be small and the durability can be improved accordingly.

In the prior art shown in FIGS. 7 and 8, the bolt 8 is inserted into the bottom portion of the case 2 via the grommet 6 and the collar 7, so that sufficient sealing performance is required for this portion. However, in contrast to this, in the present embodiment, the air cleaner 1 is not provided with a hole into which a grommet or the like is inserted, so that the sealability is excellent by this amount.

In the prior art shown in FIGS. 7 and 8 described above, since the fixing bolt 8 or nut is provided inside the case 2, after the cap 3 is assembled, the bolt 8 or nut is tightened, and thus the air cleaner. Although it takes time to confirm the support state of No. 1, in the present embodiment, since the bracket 14 presses the air cleaner 1 from the upper side to support it, the support state can be confirmed quickly.

[0023]

Since the present invention has the engine air cleaner support structure configured as described above, the air cleaner is fixed to the vehicle body without disassembling the air cleaner. Since it is not necessary to perform the work, the number of assembling steps can be reduced accordingly, and the cost of the product can be reduced. Further, since the air cleaner is not disassembled, dust or the like that may be generated at the time of disassembly does not occur. The bracket presses the air cleaner from the upper side to support it, and the load on the bracket is small, so the durability is improved by this amount.
