Description

[Detailed Description of the Invention] A. Purpose of the Invention (1) Field of Industrial Application The present invention drives auxiliary equipment for automobiles, such as a hydraulic pump for power steering, a generator, a compressor for air conditioning, and an engine for driving them. TECHNICAL FIELD The present invention relates to a splash guard arranged in an engine room so as to cover a power transmission device and the like, and particularly to an improvement of a splash guard having a tool hole through which a maintenance tool can be inserted.

(2) Conventional Technology In automobiles, it has been widely practiced to cover auxiliaries with splash guards in order to prevent splashes splashed by wheels from hitting auxiliaries. In this case, a tool hole through which a maintenance tool can be inserted is formed in the splash guard so that the engine and accessories can be maintained without being disturbed by the splash guard, and is normally closed with a cap.

(3) Problems to be Solved by the Invention However, with the splash guard as described above, it is not only troublesome to remove the cap when inserting the tool into the tool hole, but also the fear of losing the cap. is there.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a splash guard for an automobile that can prevent splashing of water into a tool hole without a cap.

B. Configuration of the Invention (1) Means for Solving the Problems In order to achieve the above-mentioned object, the present invention has a free end extending toward the center of the tool hole and a circumferential direction with a slit interposed therebetween in the circumferential direction. It is characterized in that a plurality of elastic plate pieces arranged side by side are projected.

(2) Operation According to the above configuration, the tool hole is normally closed by a plurality of plate pieces, and only the slits are present between the plate pieces, so that the water spray scattered by the wheels enters the tool hole. Is extremely small.

In addition, when the tool is inserted into the center of the tool hole for maintenance of the engine and accessories, the elastic plate piece is bent inside the splash guard by the tool to open the tool hole appropriately and allow the tool to enter. .

(3) Embodiment An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, a wheel house 3 is fixed to both sides of the front portion of the vehicle body 1 to cover the left and right front wheels 2, respectively. An engine room 4 is defined between the left and right wheel houses 3, and an engine 5 is arranged therein.

As shown in FIG. 4, this engine 5 has one end of a crankshaft 6 protruding to one side, and a drive pulley 7 having large and small pulleys 7a and 7b is splined at the end thereof. It is fitted and fixed by the bolt 8.

In the engine room 4, a power steering hydraulic pump 9, a generator 10 and an air conditioning compressor 11 are arranged in front of the engine 5. A belt 13 is suspended between the driven pulley 12 fixed to the drive shaft of the hydraulic pump 9 and the small pulley 7b, and the driven pulleys 14 and 15 fixed to the drive shafts of the generator 10 and the compressor 11 and The belt 16 is suspended around the large pulley 7a. Therefore, during operation of the engine 5, the rotation of the crankshaft 6 causes the hydraulic pump 9, the generator 10 and the compressor 11 to be belt-driven.

The drive pulley 7 is located below the wheel house 3, and a splash guard 17 that covers the lower side surface and the lower surface of the engine 5 together with the drive pulley 7 is bolted to the vehicle body and the wheel house.

The splash guard 17 is molded from a synthetic resin having appropriate elasticity, and at the time of molding, a tool hole 18 coaxial with the bolt 8 is formed at the portion facing the bolt 8 and a tool is formed from the periphery of the tool hole 18. A plurality of elastic plate pieces 19 having the same shape and projecting toward the center of the hole 18 are integrally formed.

The tool hole 18 and the elastic plate piece 19 will be described in detail with reference to FIG. 3. The tool hole 18 has a polygonal shape, and the elastic plate pieces 19 are arranged every other side. Each elastic plate piece 19 is formed into a substantially isosceles triangle with the free end facing the center of the tool hole 18 as the apex, and by doing so, a slit 20 of the same width is formed between each adjacent plate piece 19, 19. It

Further, a small slit 21 that bites into each plate piece 19 is extended from the end portion of each slit 20 on the splash guard 17 side, whereby a constricted portion 19a is formed at the base end portion of each plate piece 19. Due to the bending of the constricted portion 19a, each plate piece 19 can be easily bent inward and outward of the splash guard 17.

Next, the operation of this embodiment will be described.

Usually, the tool hole 18 is closed by a plurality of plate pieces 19,
Since only the slits 20 and 21 are present between them, even if the water splashes scattered by the wheels go toward the tool hole 18 during traveling, it is extremely unlikely that they will enter the tool hole 18. Therefore, the splash guard 17 is driven by the drive pulley 7 and the belts 13,1.
The contact part with 6 can be protected from the above splashes.

Next, for maintenance of the engine 5 and the like, a wrench W is inserted into the center of the tool hole 18, as shown in FIG.
Then, the elastic plate piece 19 is splash guarded by the wrench W.
It is bent inside 17 and the tool hole 18 is opened appropriately, and the wrench W
Is allowed to enter. In this case, since the tool holes 18 are arranged coaxially with the bolts 8 and the plurality of elastic plate pieces 19 have the same shape,
The wrench W is guided by these elastic plate pieces 19 and can be easily fitted to the head of the bolt 8.

Then, if the wrench W fitted to the head of the bolt 8 is rotated in the tightening direction, the crankshaft 6 is rotated, which can contribute to the inspection and maintenance of each part of the engine. Also, bolt 8
The drive pulley 7 can also be removed from the crankshaft 6 by loosening. In this case also, the wrench W is supported by the plurality of elastic plate pieces 19 and does not fall off, so that the rotating operation can be performed accurately.

After maintenance, if the wrench W is pulled, the plate piece 19 is bent to the outside of the splash guard 17 this time, so that the wrench W can be pulled out. After pulling out the wrench W, the plate piece
The elasticity of 19 causes the tool hole 18 to close again.

C. Effect of the Invention As described above, according to the present invention, a plurality of elastic plate pieces, which extend in the free end toward the center of the tool hole and are arranged in the circumferential direction across the slit, are provided at the periphery of the tool hole. Even if the cap is not provided, only the slit is present, so that it is possible to suppress the invasion of water spray into the tool hole as much as possible. Moreover, due to the bending of the elastic plate piece, it is extremely easy to insert and remove the maintenance tool into and from the tool hole, which can contribute to the improvement of the maintainability of the engine and the accessories.
