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

In FIG. 1 showing a side portion of an engine room of an automobile, 1 is a wheel apron, which is an upper vertical panel portion 1a constituting a side wall of the engine room E and a lower edge of the upper vertical panel portion 1a. A horizontal panel portion 1b extending inward from the vehicle body,
A closed vertical section having a lower vertical panel section 1c extending substantially vertically downward from an inner edge of the horizontal panel section 1b, and a front side frame 2 joined to the lower vertical panel section 1c and extending in the vehicle longitudinal direction. The structure is formed.

A washer tank 3 which is a heat shield container is disposed in a space below the horizontal panel portion 1b, and an engine room E is provided through an opening 1d formed in the horizontal panel portion 1b.
Facing inside. The washer tank 3 has a recess 3 at the top.
a is formed, and the control unit 4 is disposed in the recess 3a. Then, an air cleaner 5 as a vehicle accessory is provided on the lateral panel portion 1b so as to cover the control unit 4 (see FIG. 2), and heat enters through the opening 1d of the lateral panel portion 1b to control the vehicle. -It is configured so as not to affect the unit 4. In particular, the air cleaner 5 is one through which fresh air flows, and the temperature thereof is unlikely to rise, which is advantageous for avoiding heat damage.

The temperature on the lower side of the horizontal panel portion 1b is much lower than that on the upper side, which is close to the outside air temperature, but it is still high when the traffic is heavy in summer. Therefore, in this example, the control unit 4
Is disposed in the recess 3a of the washer tank 3 so as to be surrounded by the liquid and the temperature is unlikely to rise.

Further, since the wiring 7 of the pump 6 for supplying the washing liquid for the washer tank 3 is connected and wired to a power source arranged at a portion different from the washer tank 3, it usually tends to be long. In the example, the connection wiring from the pump 6 to the control unit 4 in the concave portion 3a of the tank 3 may be supplied from the control unit 4 so that the connection wiring with the power supply can be shortened. That is, the pump 6 is assembled with the washer tank 3, and the pump wiring up to the control unit 4 requires the wiring of the pump 6 and the power source, the wiring of the pump 6 and the control unit 4, and the wiring of two systems. However, one system of wiring is sufficient, and the wiring can be simplified. By doing so, it suffices to assemble the control unit 4 in the washer tank 3 in a sub-assembled state, and then assemble only the wiring of the control unit 4.

Further, as shown in FIG. 3, the pump 6A is arranged in the washer tank 3A, and the connector 6a of the pump 6A is projected from the recess 3b.
By sub-assembling a control unit 4A having a detachable connector 4a on both sides a
Wiring between the pump and the control unit can be omitted by connecting a and 6a. Further, by this, the wiring is not cut (broken) at the time of assembly, and there is no problem that the wiring is idle and an abnormal noise is generated after the vehicle is completed. Further, it becomes possible to omit a clip or the like which is conventionally required for securing the wiring, the number of mounting holes provided in the body panel is reduced, and it is effective for noise outside the vehicle compartment. Further, since the pump 6A is below the control unit 4A in the washer tank 3A, the pump noise is unlikely to leak outside the vehicle.

By the way, when the control unit is provided in the recess of the washer tank, the cleaning liquid may enter the recess when the user injects the cleaning liquid into the washer tank. There is. This is because the washer tank cannot be provided with a water drain hole in its lower portion due to blow molding.

Therefore, for example, as shown in FIGS. 4 and 5, the edge portion of the opening 3d of the lateral panel portion 3b is bent vertically upward to form a vertical portion 3e, and the washer tank 1 is used.
The peripheral wall portion 13b of the concave portion 13a of No. 3 is a convex portion projecting upward, and the air cleaner 12 is provided thereon with the seal member 11 interposed therebetween.
By disposing, the seal member 11 can form a double seal structure between the vertical portion 3e and the peripheral wall portion 13b. The peripheral wall portion 13b which forms the periphery of the recess 13a of the washer tank 13 projects above the vertical portion 3e of the opening 3d of the lateral panel portion 3b adjacent thereto. The air cleaner 12 has an upper casing 12a.
An element (not shown) is provided inside the casing formed by joining the lower casing 12b and the casing.

With this structure, the vertical portion 3e of the lateral panel portion 3b and the peripheral wall portion 13b of the washer tank 13 have a double-wall structure, so that even if the seal member 11 is deteriorated, water will not be absorbed. It has a structure that is hard to enter. And
Even if water exceeds the vertical portion 3e, the water is discharged through the gap S between the vertical portion 3e and the peripheral wall portion 13b of the washer tank 13. Moreover, the vibration of the air cleaner 12 is surely prevented by interposing the seal member 11. The inner side surface 13c of the peripheral wall portion 13b of the washer tank 13 is a taper surface, and is configured to function as a guide guide when the control unit is assembled in the recess (FIG. 6). reference).

Further, in this case, the air cleaner 12 may be attached to the washer tank 13 in order to prevent intake noise, vibration and the like from entering the passenger compartment.

Stud bolt 21 is installed upright from 3 and air cleaner 12
The nut 22 can be applied to the mounting portion 12c of the lower casing 12b to fasten and fix the same. With this configuration, since the washer tank 13 is made of synthetic resin, the vibration damping effect of the synthetic resin greatly contributes to the reduction of vibration. Although there is a concern that the weight of the air cleaner 12 may be applied to the washer tank 13, this structure has
The contact member 11 contacts the peripheral edge of the opening of the horizontal panel portion 3b,
Since the weight is supported on the entire circumference, there is no large input.

As shown in FIG. 3, the battery 31 is placed on the battery tray 32, and the double seal structure is left as it is.
A weight of 1 can be used to enhance the sealing effect.
As shown in FIG. 11, the attachment portion 32a of the battery tray 32 is fastened and fixed by applying a bolt 34 to the nut 33 fixed to the lateral panel portion 3b. Since the temperature of the battery 31 hardly rises, the temperature rise of the control unit 4 can be prevented. At the same time, it is possible to prevent battery fluid from entering.

Further, when the control unit 4 is housed in the recess, there is no space for the operator's fingers or hands to take out the control unit 4 for maintenance or the like, which makes the work difficult. As shown in FIGS. 12 and 13, the casing 41 of the control unit 4 may be integrally formed below the air cleaner 12 (or the battery tray). If you do this,
By removing the air cleaner 12, the control unit 4 can also be taken out from the recess 13a of the washer tank 13 at the same time, and the work of taking out the control unit 4 becomes smooth. Moreover, since the sub-assembly can be carried out at the time of assembling in the factory, the assembling work is easy.

Further, when a battery is used, a problem occurs when the battery solution is harnessed. Therefore, as shown in FIGS. 14 and 15, the cover & tray 3 of the battery 31 is used.
The wiring portion 51 is integrally provided on the side portion of 2A, and the connection portion 51a of the wiring portion 51 with the connector 52 is provided with the cover & tray 32.
The position may be higher than the A battery outlet 32b. It is also possible to provide a cover (not shown) on the battery outlet 32b so that the battery fluid does not directly come into contact therewith.

When an air cleaner is used, as shown in FIG. 16, both casings 12d and 12 are provided on the side portions of the upper and lower casings 12d and 12e of the air cleaner 12A.
The wiring portions 61 and 62, which are electrically connected to each other by the connection of e, are integrally provided, and the upper casing 12d is provided with the air flow.
