The elastic member 10 is a vibration-proof member made of an elastic material such as rubber. As shown in FIGS. 4 and 5, a plurality of elastic members 10 (here, two each) are provided at the left-right end of the pump 1. In the above, two elastic members 10 are provided at each end of the pump 1, but the present invention is not limited to this, and for example, one or three or more elastic members 10 may be provided.

Further, the position where the elastic member 10 is provided in the pump 1 is not limited to the above-mentioned end portion in the left-right direction, and may be another position such as the end portion in the up-down direction. The elastic member 10 is fixed to the pump 1 by the fixing portion 50, and the fixing portion 50 will be described later.

FIG. 6 is an enlarged perspective view of the elastic member 10. As shown in FIG. 6, the elastic member 10 is formed in a cylindrical shape having a hollow portion 11 inside, for example. The shape of the elastic member 10 shown in FIG. 6 is merely an example and is not limited, and may be another shape such as a prismatic shape.

The elastic member 10 includes a step portion 12 and a groove portion 14. The step portion 12 is formed on the inner peripheral surface of the elastic member 10 that forms the hollow portion 11. For example, the step portion 12 is a portion formed in a stepped shape by forming a portion having an inner diameter smaller than the inner diameter on the end side on the inner peripheral surface of the elastic member 10.

The groove portion 14 is formed along the circumferential direction on the outer peripheral surface of the elastic member 10. For example, the groove portion 14 is formed by reducing the diameter of the vicinity of the center of the outer peripheral surface of the elastic member 10. The elastic member 10 configured as described above is fixed to the fixing portion 50 provided in the pump 1 (see FIG. 4).

Since the elastic member 10 is fixed, the fixing portion 50 is provided at the left-right end portion of the pump 1 in the same manner as the elastic member 10 described above. The fixing portion 50 may be provided integrally with the pump 1 or may be provided separately.

As shown in FIGS. 7 and 8, the fixing portion 50 includes a hole 51 through which the elastic member 10 is inserted, and a notch groove 52 that communicates with the hole 51 and extends in the left-right direction. That is, the hole 51 of the fixing portion 50 has a substantially U-shaped hole shape (see FIG. 8).

As shown in FIG. 7, the elastic member 10 is fixed to the fixing portion 50 by locking the groove portion 14 at the position of the hole 51. As a result, the elastic member 10 is securely fixed to the fixing portion 50, and thus the elastic member 10 can be prevented from falling off.

Further, since the fixing portion 50 is provided with the notch groove 52, for example, when the elastic member 10 is attached to the fixing portion 50, it can be easily attached by pushing it from the notch groove 52 toward the hole 51. Therefore, the workability of mounting can be improved.

The shape of the fixing portion 50 is not limited to the above, and may be another shape such as, for example, removing the notch groove 52 to make the hole 51 annular (substantially O-shaped). good. Further, the fixing portion 50 will be described in more detail later.

Next, the bracket 20 will be described. As shown in FIG. 3, the bracket 20 is provided upright on the back door 101. The bracket 20 is made of metal, for example, but is not limited thereto.

The bracket 20 is formed, for example, in a substantially U shape in a plan view. Specifically, the bracket 20 includes a bottom portion 21, a leg portion 22, and a receiving portion 23. The bottom portion 21 is formed in a thin plate shape and is attached to the back door 101 by, for example, a double-sided tape (not shown) which is an adhesive member. That is, the mounting device 2 (pump 1) is mounted on the back door 101 by double-sided tape. The bottom portion 21 is not limited to the double-sided tape described above, and may be attached to the back door 101 by an adhesive member such as an adhesive.

The leg portion 22 extends forward from the left-right end of the bottom portion 21 and is formed so as to stand up from the back door 101.

The receiving portion 23 is continuously extended in the left-right direction from the front end portion of the leg portion 22. Further, the receiving portion 23 is formed so as to be substantially parallel to the back door 101. When the pump 1 is attached to the back door 101, the receiving portion 23 having the above-mentioned shape comes into contact with the attachment member 30 to receive the attachment member 30. Further, as shown in FIG. 5, a screw hole 23a through which a screw 60 described later is inserted is formed in the receiving portion 23.

Next, the mounting member 30 will be described. As shown in FIG. 7, the mounting member 30 is a member that connects the above-mentioned bracket 20 and the elastic member 10 to mount the pump 1 on the back door 101.

As a result, for example, even when vibration is generated in the pump 1, the elastic member 10 can attenuate the vibration, so that the vibration transmitted to the mounting member 30, the bracket 20, and the back door 101 is suppressed. be able to.

Further, in the present embodiment, as shown in FIG. 7, the elastic member 10 provided in the pump 1 is not directly connected to the bracket 20, but is attached to the bracket 20 via the attachment member 30. Therefore, the elastic member 10 provided in the pump 1 is indirectly connected to the bracket 20 by the mounting member 30. Thereby, for example, even if some impact is received from the bracket 20 side, it is buffered by the mounting member 30 or the like, and thus it is possible to suppress the elastic member 10 from falling off from the pump 1. Hereinafter, the configuration of the mounting member 30 will be described in detail.

FIG. 9 is an enlarged perspective view of the mounting member 30. As shown in FIGS. 9 and 7, the mounting member 30 includes a facing portion 31, a shaft portion 32, a peripheral wall portion 33, a screw mounting portion 34, and a movement restricting portion 35 (shown in FIG. 9). The mounting member 30 is made of resin, for example, but is not limited thereto.

As shown in FIG. 7, the facing portion 31 is a portion located facing the receiving portion 23 of the bracket 20 when the pump 1 is attached to the back door 101, and is substantially parallel to the receiving portion 23. ..

The shaft portion 32 is formed, for example, in a substantially columnar shape. As shown in FIG. 7, the shaft portion 32 is formed so as to project from the facing portion 31 toward the receiving portion 23 of the bracket 20. Then, the shaft portion 32 is fitted with the elastic member 10.

Specifically, the shaft portion 32 is inserted into the hollow portion 11 of the elastic member 10 fixed to the fixed portion 50 and fitted with the elastic member 10. In this way, since the shaft portion 32 is inserted into the hollow portion 11 and fitted to the elastic member 10, it is possible to prevent the elastic member 10 from coming off from the shaft portion 32 even when an unexpected impact is received.

As shown in FIG. 7, the elastic member 10 through which the shaft portion 32 is inserted is sandwiched between the receiving portion 23 of the bracket 20 and the facing portion 31 of the mounting member 30. Specifically, the fixed portion 50 is arranged so as to be located between the receiving portion 23 and the facing portion 31, so that the elastic member 10 fixed to the fixing portion 50 is located between the receiving portion 23 and the facing portion 31. It is sandwiched between.

As a result, the elastic member 10 is less likely to fall off from the tip portion 32a side of the shaft portion 32, that is, the receiving portion 23 of the bracket 20, and can be effectively suppressed from falling off.

Further, a gap may be formed between the tip portion 32a of the shaft portion 32 and the receiving portion 23. In the present embodiment, the elastic member 10 is further suppressed from falling off by appropriately setting the size of the gap and the fixing portion 50.

Specifically, as shown in FIG. 7, the shaft portion 32 is formed so that the separation distance A1 between the tip portion 32a and the receiving portion 23 is smaller than the thickness A2 of the fixed portion 50 (A1 <A2).

Since the elastic member 10 is fixed to the fixing portion 50, the elastic member 10 is thicker than the thickness A2 of the fixing portion 50. Therefore, for example, even if the elastic member 10 is damaged due to aged deterioration or the like, if the gap and the fixing portion 50 are set as described above, it is possible to prevent the elastic member 10 from falling out of the gap.

Further, in the present embodiment, the sizes of the fixing portion 50 and the shaft portion 32 are appropriately set so that the elastic member 10 is further suppressed from falling off.

Specifically, as shown in FIG. 8, the fixing portion 50 is formed so that the width B1 of the notch groove 52 is smaller than the diameter B2 of the shaft portion 32 fitted to the elastic member 10 inserted into the hole 51. (B1 <B2).

Since the elastic member 10 is fitted to the shaft portion 32 as described above, the elastic member 10 has a diameter larger than the diameter B2 of the shaft portion 32. Therefore, for example, even if the elastic member 10 is damaged due to aged deterioration or the like, if the notch groove 52 and the shaft portion 32 of the fixing portion 50 are set as described above, it is difficult for the elastic member 10 to fall out of the notch groove 52. can do.

As shown in FIG. 9, the shaft portion 32 includes a locking portion 32b at the tip portion 32a. FIG. 10 is an enlarged view of the shaft portion 32 when viewed from the tip portion 32a side. As shown in FIG. 10, the locking portion 32b is formed so as to project along the radial direction on the outer peripheral surface of the shaft portion 32.

Three locking portions 32b are formed on the outer peripheral surface of the shaft portion 32 at intervals of 120 degrees, but this is merely an example and is not limited. That is, the number of locking portions 32b may be two or less, or four or more, and may not be formed at equal intervals.

As shown in FIG. 7, the locking portion 32b described above is locked to the elastic member 10 fixed by the fixing portion 50. Specifically, the locking portion 32b of the shaft portion 32 is locked to the stepped portion 12 of the elastic member 10.

Thereby, for example, when the mounting member 30 fitted to the elastic member 10 is assembled to the bracket 20, the elastic member 10 can be effectively prevented from falling off from the shaft portion 32.

As shown in FIG. 9, the peripheral wall portion 33 is formed so as to partially surround the periphery of the shaft portion 32. As a result, a space is formed between the shaft portion 32 and the peripheral wall portion 33, and the elastic member 10 can be positioned in such a space (see FIG. 7). Therefore, the peripheral wall portion 33 can function as a cover that protects the elastic member 10.

In the above, the peripheral wall portion 33 is designed to partially surround the periphery of the shaft portion 32, but the present invention is not limited to this, and the peripheral wall portion 33 may be surrounded over the entire circumference.

The screw mounting portion 34 is formed so as to be continuous with the facing portion 31 and the peripheral wall portion 33, and the screw insertion hole 34a is formed. The screw insertion hole 34a is formed at a position corresponding to the screw hole 23a of the receiving portion 23 of the bracket 20 described above. As a result, the mounting member 30 is fastened and fixed to the bracket 20 by inserting the screw 60 into the screw insertion hole 34a and the screw hole 23a.

The movement restricting unit 35 (see FIG. 4) restricts the movement of the mounting member 30 fastened and fixed to the bracket 20 toward the pump 1. FIG. 11 is an enlarged view of the movement control unit 35.

As shown in FIGS. 11 and 9, the movement restricting portion 35 is formed at a position on the pump 1 side of the mounting member 30, and is formed in a concave shape. On the other hand, a convex convex portion 55 is formed at a position corresponding to the movement restricting portion 35 in the pump 1.

The shape of the movement restricting portion 35 is not limited to the above, and may be another shape such as being formed in a convex shape and having a concave portion on the pump 1 side.

Then, for example, when an external force acts in the direction indicated by the arrow D in FIG. 11 and the mounting member 30 moves toward the pump 1, the movement restricting portion 35 first abuts on the convex portion 55 of the pump 1 and the mounting member Regulate more than 30 movements.

As a result, for example, the shaft portion 32 and the like are easily affected by an external force, but by providing the movement restricting portion 35, the movement of the mounting member 30 is restricted, so that the influence of the external force can be reduced and the shaft portion can be reduced. 32 and the like can be protected.

As described above, the mounting structure of the drive device according to the embodiment includes a bracket 20, an elastic member 10, and a mounting member 30. The bracket 20 is provided on the back door 101 (an example of the attached member). The elastic member 10 is provided in the pump 1 (an example of a driving device). The mounting member 30 connects the bracket 20 and the elastic member 10 to mount the pump 1 on the back door 101. This makes it possible to prevent the elastic member 10 from falling off.

I made it possible. Here, a case where the locking member 38 is a screw will be described as an example.

Specifically, in the shaft portion 32, a screw hole 32c is formed at the tip portion 32a. Then, the locking member 38 (that is, the screw) having the head 38a is inserted into the screw hole 32c and attached. At this time, the head 38a of the locking member 38 is locked to the step portion 12 of the elastic member 10.

Thereby, for example, when the mounting member 30 fitted to the elastic member 10 is assembled to the bracket 20, the elastic member 10 can be effectively prevented from falling off from the shaft portion 32.

In the above, the screw is used as the locking member 38, but the present invention is not limited to this, and for example, a pin having a head may be used.

(Second modification)
Next, a second modification will be described with reference to FIG. FIG. 13 is a diagram illustrating a second modification.

As shown in FIG. 13, in the second modification, a screw 60 for attaching the mounting member 30 to the bracket 20 is provided on the shaft portion 32. Specifically, in the shaft portion 32 according to the second modification, a screw insertion hole (an example of the insertion hole) 32d is formed along the axial direction. Further, in the bracket 20, a screw hole 23b is formed at a position corresponding to the screw insertion hole 32d.

Then, the mounting member 30 is fastened and fixed to the bracket 20 by inserting the screw 60 into the screw insertion hole 32d and the screw hole 23b.
