By integrating the multiple objects and the stopper volumetrically in the recess, and pressing the objects on both sides of the recess in this integrated state, the multiple objects can be removed from the recess. This is to prevent it from falling off.

[Embodiment 1] Fig. 1 is an exploded perspective view showing an attachment structure to a tank according to an embodiment of the present invention, Fig. 2 is an assembled perspective view thereof, and Fig. 3 is a cross section along the line shown in Fig. 2. It is a diagram.

In this embodiment, the structure for attaching the tank is such that two wash pumps are attached to the washer tank for storing the washing liquid and for spraying the washing liquid in the tank onto the window glass surface. However, the water tank is now permanently installed in the engine compartment of a car.

The washer pump 1 has a composite structure that integrally incorporates a centrifugal pump and a motor (both not shown) for driving the centrifugal pump, and has a substantially cylindrical outer shape. On the outer circumference of the washer pump 1, a suction pipe 2 formed with a large diameter, a discharge pipe 3 formed with a small diameter, and a terminal unit 4 for supplying driving power to a motor are arranged. The pipe 2 and the terminal unit 4 project in the radial direction at positions having an opening angle of about 180 degrees from each other, and the discharge pipe 3 projects in the substantially tangential direction at a position below the terminal unit 4. A bushing 5 is fitted to the outer periphery of the suction pipe 2 of the washer pump 1, and the bushing 5 is made of an elastic material such as rubber and has a relatively thick cylindrical shape with a tapered slope at the tip of the outer periphery. It is molded into.

The washer tank (only the lower part is shown) 6 is integrally molded into a hollow body of a desired shape using synthetic resin, and a recess 7 is simultaneously molded in the lower part thereof. The recess 7 has an open front and lower surface, and the opening dimension W is approximately equal to twice the diameter D of the wash pump 1, and the depth S thereof is set smaller than the diameter D of the wash pump 1. There is. At the lower part of both sides of the recess 7, a pair of engaging parts 8 integrally formed into a vertically elongated substantially semi-cylindrical shape are arranged so as to face each other and protrude inwardly. 8 is set to be smaller than twice the diameter D of the washer pump 1. A small-diameter depression 9 into which the tip of a stopper (to be described later) is inserted is provided at approximately the center of the bottom of the recess 8, and at both sides of the depression 9, holes for inserting the suction pipe of the washer pump are provided. Each through hole 10 is opened so as to communicate with the inside of the washer tank 6. A protrusion 11 is vertically arranged between the through holes 10 on both sides and protrudes in a chevron shape.

The stopper 12 is integrally molded from a synthetic resin into a substantially wedge shape, and the enlarged portion 13 has an outer shape of a column having a substantially home base-shaped cross section and a hollow portion 14 having a similar shape. Both sloped portions 15 of the enlarged portion 13 are formed into concave arcuate surfaces that substantially match the cylindrical surface of the washer pump 1, and both of these arcuate surfaces form a vertically elongated bulge portion 16 that bulges out slightly at the tip of the enlarged portion 13 of the stopper 12. are doing. The end of the stopper 12 from this bulge 16 is tapered in the vertical direction, and the tip 17 is bifurcated by cutting a vertical groove 18 approximately along the center in the width direction. .

Next, the assembly work and operation of each article according to the above configuration will be explained.

First, two washer pumps 1 are housed in the recess 7 of the washer tank 6 so as to be adjacent to each other and standing upright on the left and right. At this time, wash pump 1
When the suction pipe 2 is fitted with the bushing 5 in the through hole 10 formed in the back wall of the recess 7,
When inserted, they communicate with the internal chamber of the washer tank 6.

When the two washer pumps 1, 1 are arranged side by side and housed in the recess 7, the opening dimension w between the engaging parts 8, 8 protruding from both sides of the recess 7 is twice the diameter D of the washer pump 1. Since it is set to be slightly smaller than the original size, it seems to be an obstacle to containment operations. However, since the two washers pumps 1, 1 are pushed closely together, the width w of the two engaging parts 8, 8 and the width 2×D of the two washers pumps 1, 1 that are in close contact with each other.
Since the difference between the
The work of accommodating the washer pumps 1, 1 in the recess 7 can be easily carried out by climbing over the engaging parts 8, 8, regardless of the existence of them.

When the two washer pumps 1,1 are housed next to each other inside the recess 7, the stopper 12 is pushed between the two washer pumps 1,1. At this time, the tip 17 of the stopper 12 is inserted into the recess 9 formed in the back wall of the recess 7. stoppa 12
The distal end portion 17 is bifurcated by cutting a vertical groove 18, so that when inserted into the recess 9, by pressing against the inner periphery of the recess 9, the stopper 12 can be moved in the vertical direction. The position of is now determined.

Due to the wedge effect caused by pushing in the stopper 12, both the washer pumps 1, 1 are pushed outward, so that the washer pumps 1, 1
The outer circumferential surface of the recess 7 is pressed against both side surfaces of the recess 7. Due to the reaction force from both side walls of the recessed portion 7 due to this pressing, the both side slope portions 15, 15 of the stopper 12 are
are in a pressed state along the curvature of the outer periphery facing surfaces of both the washer pumps 1,1. As a result, both the washer pumps 1, 1 and the stopper 12 are connected to the recess 7.
It becomes as if they are integrated inside the recess 1, and is fixed and housed inside the recess 1 while being biased with elastic force.

In this stored state, the engaging parts 8, 8 protruding from both side surfaces of the recess 7 are engaged with a part of the outer peripheral surface of both the washer pumps 1, 1, respectively. The washer pumps 1, 1 and the stopper 12 are prevented from falling out of the recess 7 by the engaging portions 8, 8.
Further, since the bulging portion 16 of the stopper 12 is located on the back side of the line connecting the centers between the two wash pumps 1, 1, the stopper 12 becomes in a state of being prevented from coming off.

Furthermore, the pressed state of both the washer pumps 1, 1 with the recessed part 7 and the stopper 12, and the engaged state of both the washer pumps 1, 1 with both the engaging parts 8, 8 are as follows: This is further strengthened by the elastic biasing force of the bushing 5. That is, since the recessed part 7 is integrally formed with the side wall of the hollow washer tank 6, the engaging part 8 is formed in a cylindrical shape, and the stopper 12 has a hollow part 14 formed in the enlarged part 13. Since the bushing 5 is made of an elastic material, it generates an elastic biasing force in the pressed and engaged states.

In this embodiment, the discharge pipe of one washer pump is arranged at a predetermined position so as to spray the cleaning liquid onto the front window glass surface, and the discharge pipe of the other washer pump is arranged at a predetermined position so as to spray the cleaning liquid onto the rear window glass surface. are connected to the respective nozzles via hoses, etc.

According to this embodiment, since two wash pumps can be fixedly attached to one recess, the structure can be simplified compared to the case where a recess is provided for each wash pump, and the molding of the wash tank can be simplified. Not only can it be simplified, but also its capacity can be increased.

The installation work is extremely simple as the two wash pumps can be fixedly attached to the wash tank at the same time by simply inserting the two wash pumps side by side into one recess and press-fitting the stopper between both wash pumps. can be used to improve assembly workability.

Since two wash pumps can be installed in one recess, the efficiency of subsequent work such as connecting the hose to the discharge pipe can be improved, and even if the width of the wash tank is narrow, the wash pump can be installed easily. Two can be installed.

After being stored in the recess, the two washer pumps are integrated by the stopper, and are prevented from coming off by the engaging parts on both sides of the recess, so that the washer pump can be securely fixed to the washer tank. It can be installed by

When stored in the recess, the two washer pumps are constantly subjected to biasing force by the recess, the engaging part, and the stopper, which makes the fixation even stronger and prevents them from loosening naturally due to vehicle vibrations, etc. can.

[Embodiment 2] FIG. 4 is an exploded perspective view showing another embodiment of the present invention.

The difference between this embodiment and the first embodiment is that three wash pumps 1a, 1b,
1c is stored and attached to the wash tank at the same time.

That is, the opening dimension of the recess 7A is set to approximately three times the diameter D of the washer pump, and a pair of stoppers 12A and 12B are provided between the left and right washer pumps 1a and 1b and the center washer pump 1c, respectively. is inserted. Both stoppers 12A and 12B are fixedly connected to each other and integrated at a connecting portion 12C formed on the back surface thereof, and these integrated stoppers 12A and 12B are placed on the outer periphery of the central washer pump 1c. In the fitted state, the central washer pump 1c is inserted between the left and right washer pumps 1a and 1b when it is pushed in.

In this embodiment, by inserting both stoppers 12A and 12B, the left and right washer pumps 1a and 1b are pushed outward, respectively, and the recess 7A is pushed outward.
This results in a state in which three washer pumps and two stoppers are integrated. The immobilization effect accompanying this integration is the same as in Example 1 above.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and may be modified without departing from the gist thereof.
It goes without saying that various changes are possible.

For example, the structure, shape, etc. of the washer pump, recess, stopper, etc. are not limited to those in the above embodiments.

The bushing, the recess for inserting the stopper tip, the hollow part of the stopper, the vertical groove, etc. can be omitted.

The present invention is not limited to a structure in which a wash pump is attached to a wash tank, but can also be applied to a structure in which a motor, dry battery, etc. are attached to other tanks.
