Embodiments of the present invention will now be described in detail with reference to the drawings.

In FIG. 1 showing a schematic structure, 1 is a wheel.
An upper vertical panel portion 1a forming a side wall of the engine room E, a horizontal panel portion 1b extending inward from the lower edge of the upper vertical panel portion 1a, and an inner edge portion of the horizontal panel portion 1b. The lower vertical panel portion 1c extends substantially vertically downward.

The horizontal panel portion 1b of the wheel apron 1
1d has an opening 1d formed therein, and a washer tank 2 as a heat shield container having a recess 2a formed in the upper portion thereof is disposed in a space below the opening 1d. An opening 2b is formed in the washer tank 2 on the side of the fender panel 3 side. On the other hand, an air cleaner 4 that penetrates the opening 1d and reaches the inside of the recess 2a is provided, and an intake port 4c of the air cleaner 4 is arranged corresponding to the opening 2b, and a wheel apron is provided through the opening 2b. Air is taken in from inside the fender panel 3 below 1. The air cleaner 4 is formed by joining an upper casing 4a and a lower casing 4b, and a filter element (not shown) is arranged inside. The opening 2b has a funnel shape so as to improve the intake efficiency at high speed.

A front side frame 5 having a hat-shaped cross section is joined to the lower vertical panel portion 1c to form a closed cross section structure extending in the longitudinal direction of the vehicle body.

Further, as shown in FIG. 2, the control unit 6 is attached to the lower portion of the protrusion 4d of the lower casing 4b of the air cleaner 4 in the recess 2a of the washer tank 2. You can also

In this way, the washer tank 2, the air cleaner 4, and the control unit 6 can be arranged by providing only one opening 1d in the lateral panel portion 1b, which is advantageous in terms of vehicle body rigidity. is there.

Further, as shown in FIGS. 3 and 4, in the washer tank 2A, an opening 2 is provided separately from the opening 2b.
e and the resonance duct 11 is connected to the washer tank 2
By sub-assembling in A and inserting the air cleaner 4 in advance, the robot can be assembled. Then, since the air cleaner 4 inserted into the recess 2a is attached and fixed to the washer tank 2A,
If the duct insertion portion 11a of the resonance duct 11 is extended to a length that can pass through the washer tank 2A and also support the air cleaner 4, fastening can be easily performed and disassembly at the time of recycling is easy.

Further, the intake noise due to the intake of the fender becomes louder as the efficiency of the engine increases, and the pulsation of the intake of the engine causes panel vibration of the front fender panel. Therefore, as shown in FIG. 5, a high-rigidity sound absorbing sheet 22 in which a foaming agent is press-fitted therein is attached to the inner surface of the front fender panel 21 by a honeycomb sheet so that the sound absorbing effect and the fender panel 21 are achieved. It is also possible to increase the rigidity of and to prevent vibration. In this case, an opening 4g for allowing the intake port 4e of the air cleaner 4A to project into the fender panel 21 is formed in the upper vertical panel portion 1f of the wheel apron 1A. The high-rigidity sound absorbing sheet 22 is used as shown in FIG.
It is attached to the back surface side of the front fender panel 21 over a range corresponding to the attachment position of the (intake port 4e).

Therefore, the intake sound generated by the intake of the air cleaner 4A is effectively absorbed by the sound absorbing sheet 22. Therefore, the sound transmitted from the inside of the fender panel to the passenger compartment through the door parting portion can be reduced. Further, the sound absorbing sheet 22 has a similar effect on the transmission of wind noise into the passenger compartment. Furthermore, sound absorbing sheet 2
Since the rigidity is increased by the attachment of No. 2, even if the plate thickness of the fender panel is thinned, the rigidity equivalent to the conventional one can be maintained.

Further, as a means for reducing the transmitted sound of the intake sound to the vehicle compartment, as shown in FIGS. 7 and 8, an air cleaner is used.
The vertical wall portion 31a is erected upward from the mudguard 31 on the vehicle rear side from the mounting position of the intake port (air intake port), and the space inside the fender panel 21 is partitioned by the vertical wall portion 31a, so that the intake noise is reduced. It is also possible to block passage into the vehicle interior. In order to make this more effective, as shown in FIG. 9, a flange portion 31b is formed around the vertical wall portion 31a, and the flange portion 31b and the inner peripheral surface of the wheel apron 1 and the fender panel 21 are formed. A sound absorbing sheet 32 having the same structure as that of the above-described sound absorbing sheet 22 is provided between them, so that the transmitted sound can be blocked and the sound inside and outside the vehicle can be reduced.

In order to eliminate the unstable mounting of the resonance duct, as shown in FIGS. 10 and 11, the resonance duct 41 is inserted into the opening 2e of the washer tank 2A and connected to the air cleaner. In addition to the attached portion 41a, an annular portion 41c having a funnel shape is provided at the intake portion via the intermediate portion 41b.
It is also possible to fit the fitting part of the above into the taper fitting into the opening 2b. In this way, the resonance duct 41
Not only is the installation stable, but the opening portion 2b serving as an intake port is extended by the annular portion 41c, so that the intake effect can be improved, and at the same time, the intake noise can be reduced.

Further, the control box stored in the recess 2a of the washer tank 2 needs to be taken in and out when the control box is out of order. As shown in FIG. 12, the bottom of the recess 2a is connected to the outside. By opening the through hole 2f, the through hole 2f functions as an air hole as well as a water draining hole, so that the control box can be smoothly taken in and out.

Furthermore, if a screw for assembling the control box is projected from the casing, the screw may interfere with the inner surface of the washer tank when it is assembled in the recess 2a of the washer tank 2. .. Therefore, in order to avoid such interference, it is conceivable to reduce the tank capacity of the washer tank as compared with the volume of the recess 2a, but this is not so desirable. Therefore, as shown in FIG. 13, the casing 6a of the control box 6A is provided with a vertical groove 6b extending in the vertical direction.
By disposing the screw 42 therein, unnecessary protrusion due to the screw can be eliminated. The vertical groove 6b also functions as an air vent groove during assembly.
