  The bracket 4 includes a leg portion 21 and a receiving portion 22 and is formed in a substantially U shape. Thereby, when the pump 1 is attached to the back door 101 via the bracket 4, a space is formed between the pump 1 and the bottom portion 20 of the bracket 4. Therefore, it is possible to prevent the vibration of the pump 1 from being directly transmitted to the back door 101 and to suppress the vibration from being transmitted to the back door 101.

  Further, in the mounting structure of the driving device, the rear end portion of the substantially bar-shaped elastic member 5 extends toward the back door 101 and contacts the back door 101. The elastic member 5 is elastically compressed between the receiving portion 22 and the back door 101. Thereby, even when the damped vibration is transmitted to the back door 101 via the bracket 4, the vibration transmitted to the back door 101 can be damped by the elastic member 5 contacting the back door 101. 101 vibration can be suppressed.

  Thus, the mounting structure of the driving device can suppress the generation of abnormal noise due to the vibration of the back door 101.

  In the mounting structure of the driving device, the mounting portion 3 and the receiving portion 22 are fastened by the elastic member 5, and the vibration transmitted to the bracket 4 by the spacer portion 31 can be attenuated and transmitted to the back door 101. Vibration can be suppressed. Thereby, the number of parts can be reduced and the cost can be reduced.

The provided second cutout groove 24 is formed in the receiving portion 22. Thereby, the elastic member 5 can be easily pierced through the first hole 10 and the second hole 23, the assembly can be facilitated, and workability can be improved.

  In the drive device mounting structure, the width of the first notch groove 11 is made smaller than the diameter of the first through portion 32 of the elastic member 5. Thereby, it can suppress that the 1st penetration part 32 which penetrates the 1st hole 10 slips out of the 1st hole 10. Further, the width of the second notch groove 24 is made smaller than the diameter of the second through portion 33 of the elastic member 5. Thereby, it is possible to suppress the second through portion 33 penetrating the second hole 23 from coming out of the second hole 23.

(Second Embodiment)
Next, a drive device mounting structure according to the second embodiment will be described with reference to FIG. Here, it demonstrates centering on a different location from 1st Embodiment. In addition, about the structure similar to 1st Embodiment, the code | symbol same as 1st Embodiment is attached | subjected and description here is abbreviate | omitted. FIG. 10 is an enlarged cross-sectional view of a part of the drive device mounting structure according to the second embodiment.

  The attachment device 2 includes an attachment portion 3, a bracket 4, an elastic member 70, and a sleeve 71. The attachment device 2 attaches the attachment portion 3, that is, the pump 1 (see FIG. 3) to the bracket 4 with a screw 72.

  A hole 73 is formed in the attachment portion 3. In addition, the 1st notch groove 11 (refer FIG. 2) of 1st Embodiment is not formed in the attaching part 3 which concerns on 2nd Embodiment. On the inner peripheral wall of the hole 73, a protruding portion 74 that protrudes inward in the radial direction of the hole 73 is formed.

  A screw hole 75 to which a screw 72 is attached is formed in the receiving portion 22 of the bracket 4. In addition, the 2nd notch groove 24 (refer FIG. 2) of 1st Embodiment is not formed in the receiving part 22 which concerns on 2nd Embodiment.

  The elastic member 70 is made of an elastic material such as rubber. The elastic member 70 is formed with a hole 80 into which the sleeve 71 is inserted, and is formed in a cylindrical shape. A groove 81 is formed on the outer peripheral wall of the elastic member 70, and a protrusion 82 is formed on the inner peripheral wall.

  The groove 81 is formed over the entire circumference of the outer peripheral wall. The protruding portion 74 of the mounting portion 3 is fitted into the groove portion 81. In addition, the groove part 81 and the protrusion part 74 of the attachment part 3 may be provided with two or more.

  The protrusion 82 is formed over the entire circumference of the inner peripheral wall. Three protrusions 82 are formed side by side in the front-rear direction. In addition, although the three protrusion parts 82 are made into an example here, the number of the protrusion parts 82 is not restricted to this, For example, the protrusion part 82 may be one. The protruding portion 82 contacts the sleeve 71.

  The elastic member 70 is sandwiched between the projecting portion 74 of the mounting portion 3 and the cylindrical portion 90 of the sleeve 71 in the radial direction, and is sandwiched between the flange 91 of the sleeve 71 and the bracket 4 in the front-rear direction.

  The sleeve 71 includes a cylindrical portion 90 and a flange 91. The sleeve 71 suppresses the elastic member 70 from being detached from the attachment portion 3 at the time of conveyance with the elastic member 70 attached to the attachment portion 3 or during attachment work. The sleeve 71 constitutes a pressing part.

  The cylindrical portion 90 is inserted into the hole 80 of the elastic member 70 and comes into contact with the protruding portion 82 of the elastic member 70. The outer diameter of the cylindrical portion 90 is larger than the inner diameter of the protruding portion 82 of the elastic member 70. Therefore, when the cylindrical portion 90 is inserted into the hole 80 of the elastic member 70, the cylindrical portion 90 presses the elastic member 70 toward the attachment portion 3.

  The flange 91 is formed at the tip of the cylindrical portion 90 opposite to the tip at which the claw portion 92 is formed. The flange 91 abuts on the elastic member 70, holds the elastic member 70 together with the bracket 4, and suppresses the elastic member 70 from coming off from the attachment portion 3.

  The flange 91 protrudes radially outward from the cylindrical portion 90. The outer diameter of the flange 91 is not less than the outer diameter of the elastic member 70. The flange 91 suppresses deformation of the elastic member 70 due to the operator's contact with the elastic member 70 at the time of attachment, and prevents the elastic member 70 from coming off the attachment portion 3.

  The sleeve 71 is formed so that the length between the flange 91 and the bracket 4 is shorter than the length of the elastic member 70. Thereby, the flange 91 can press the elastic member 70 in the front-rear direction together with the bracket 4, and can suppress the occurrence of rattling in the front-rear direction of the elastic member 70.

  In the mounting structure of the driving device, when the sleeve 71 is inserted into the elastic member 70, the protruding portion 82 of the elastic member 70 and the sleeve 71 are brought into contact with each other, and the elastic member 70 is pressed toward the mounting portion 3. Thereby, the attachment portion 3 and the elastic member 70 are brought into contact with each other, and the vibration of the motor is attenuated by the elastic member 70, so that the vibration can be prevented from being transmitted to the back door 101. In addition, it is possible to suppress the elastic member 70 from being detached from the attachment portion 3 during conveyance with the elastic member 70 attached to the attachment portion 3 or during attachment work.

  Further, the mounting structure of the driving device includes a claw portion 92 that can be engaged with the protruding portion 82 of the elastic member 70 in the direction in which the sleeve 71 is removed from the elastic member 70. Thereby, it is possible to suppress the sleeve 71 from coming out of the elastic member 70 during conveyance in a state where the sleeve 71 is inserted into the elastic member 70 or during attachment work.

  The mounting structure of the driving device includes a flange 91 that holds the elastic member 70 in the front-rear direction together with the bracket 4. Thereby, it can suppress that an operator contacts the elastic member 70 at the time of attachment operation | work, and can suppress that the elastic member 70 comes off from the attachment part 3. FIG. Further, by holding the elastic member 70 between the flange 91 and the bracket 4, it is possible to suppress the vibration of the motor from being transmitted to the bracket 4 and to suppress the vibration from being transmitted to the back door 101. .
