  As shown in FIGS. 1 and 2, the wiper motor M of the present embodiment includes a metal plate-like bracket 31. The bracket 31 has a gear housing fixing portion 32 fixed to the gear housing 23 and a vehicle body fixing portion 33 for fixing to the vehicle body S (see FIG. 2). Further, the gear housing fixing portion 32 and the vehicle body fixing portion 33 in the bracket 31 of the present embodiment are at least 45 ° with respect to a plane orthogonal to the axis L1 of the output shaft 24, and in this embodiment 90 °. It is connected via a connecting portion 34 having a tilted first plane 34a.

  Specifically, as shown in FIGS. 1 to 5, the gear housing fixing portion 32 is formed in a substantially rectangular shape. Moreover, as shown in FIGS. 3-5, the gear housing fixing | fixed part 32 has the three fastening fixing | fixed part 32a penetrated in the plate | board thickness direction. On the other hand, as shown in FIG. 2, three fixed columns 23 c that protrude in the same direction as the direction in which the output shaft 24 projects are formed on the surface 23 b of the gear housing 23 from which the output shaft 24 projects. Each fixed column 23 c is viewed from the axial direction of the output shaft 24, on the opposite side of the output shaft 24 from the mounting leg 23 a (hereinafter simply referred to as the non-mounting leg side), in other words, the gear with respect to the output shaft 24. The housing 23 is provided on the side where the worm is disposed. Each fixed column 23c is formed with a female screw 23d that opens to the tip side. The gear housing fixing portion 32 is fastened and fixed to the gear housing 23 by a screw 35 that passes through the fastening fixing portion 32a and is screwed into the female screw 23d. That is, the plane of the gear housing fixing portion 32 faces the surface 23b of the gear housing 23 on the side from which the output shaft 24 protrudes, and is on the side opposite to the mounting leg when viewed from the direction of the axis L1 of the output shaft 24. The shaft 24 is fixed to the gear housing 23 on the side where the own vehicle body fixing portion 33 is provided.

  The connecting portion 34 is provided so as to extend to the lower oblique anti-mounting leg side through a bent portion 36 bent by 90 ° from the counter-attaching leg side of the gear housing fixing portion 32 on the side close to the motor body 21. It has been.

  As shown in FIG. 3, the vehicle body fixing portion 33 has a second flat surface 33a continuous with the first flat surface 34a of the connecting portion 34, and can be fitted with a rubber bush 37 (see FIGS. 4 and 5). It has a notch 33b. As shown in FIG. 2, the vehicle body fixing portion 33 to which the rubber bush 37 is attached is fixed to the vehicle body S by a bolt 38 as a fastening member that penetrates the second flat surface 33 a and the rubber bush 37. become. It should be noted that the vehicle body fixing portion 33 of the present embodiment is disposed apart from the pair of holder vehicle body fixing portions 11b in the direction of the axis L1 of the output shaft 24 (specifically, the fixing holes of the pair of holder vehicle body fixing portions 11b) From a surface 23e (see FIG. 2) opposite to the surface 23b of the gear housing 23 from which the output shaft 24 protrudes. Is also arranged at a position on the lower side (the anti-projection direction side of the output shaft 24). Thereby, the triangular shape connecting the three points of each fixing hole 11d of the pair of holder vehicle body fixing portions 11b and the notch hole 33b of the vehicle body fixing portion 33 forms a straight line connecting the fixing holes 11d of the pair of holder vehicle body fixing portions 11b. The cutout holes 33b of the vehicle body fixing portion 33 constituting one point of the triangular shape are compared with those fixed in a horizontal arrangement parallel to a plane perpendicular to the axis L1 of the output shaft 24. The output shaft 24 is disposed below the straight line connecting the fixing holes 11d of the fixing portion 11b in the direction of the axis L1. Further, the gear housing fixing portion 32 and the connecting portion 34 of the present embodiment are formed with a pair of parallel concave and convex portions 39 and 40, respectively. The concavo-convex portions 39 and 40 are for increasing the strength compared to a simple flat plate shape, and are formed by pressing.

Next, the operation of the wiper unit configured as described above will be described.
For example, when a wiper switch provided in the driver's seat is operated, a drive current is supplied to the motor body 21, and the output shaft 24 and the lever 25 are rotationally driven. Then, the power is transmitted to each pivot lever 13 a via the link rods R 1 and R 2, and each pivot shaft 13 is rotated by reciprocatingly swinging each pivot lever 13 a, and a wiper fixed to each pivot shaft 13. Are reciprocally swung in synchronism, and the wiping operation is performed.

Next, the characteristic effects of the above embodiment will be described below.
(1) The gear housing fixing portion 32 and the vehicle body fixing portion 33 in the bracket 31 are 45 ° or more with respect to a plane orthogonal to the axis L1 of the output shaft 24, and in this embodiment, the first plane inclined by 90 °. It is connected via a connecting part 34 having 34a. Therefore, in a state in which the vehicle body fixing portion 33 is fixed to the vehicle body S, it is possible to suppress the speed reduction portion 22 and the motor main body 21 from being displaced (vibrated) in the direction along the axis L1 of the output shaft 24. . That is, since the connecting portion 34 has a first plane 34 a that is inclined at least 45 ° with respect to a plane orthogonal to the axis L 1 of the output shaft 24, the plate surface direction of the first plane 34 a is the axis of the output shaft 24. Since it becomes close to the L1 direction, it becomes difficult to bend, and as a result, the reduction part 22 and the motor main body 21 are prevented from being displaced (vibrated) in the direction along the axis L1 of the output shaft 24.

  (2) The vehicle body fixing portion 33 has a second plane 33a continuous with the first plane 34a of the connecting portion 34, and can be fixed to the vehicle body S by a bolt 38 penetrating the second plane 33a. In a state where the vehicle body fixing portion 33 is fixed to the vehicle body S, it is possible to further suppress displacement (vibration) of the speed reduction portion 22 and the motor main body 21 in the direction along the axis L1 of the output shaft 24. .

  (3) The gear housing fixing portion 32 has a flat surface facing the surface 23b of the gear housing 23 on the side from which the output shaft 24 protrudes, and is on the side opposite to the mounting leg as viewed from the direction of the axis L1 of the output shaft 24. The output shaft 24 is fixed to the gear housing 23 on the side where the own vehicle body fixing portion 33 is provided. Therefore, for example, the bracket 31 does not need to have a complicated shape that extends to the opposite side (the mounting leg 23a side) from the vehicle body fixing portion 33 while avoiding the output shaft 24.

  (4) The vehicle body fixing portion 33 is spaced from the pair of holder vehicle body fixing portions 11b in the direction of the axis L1 of the output shaft 24, and the surface 23b of the gear housing 23 on the side from which the output shaft 24 protrudes. It is arranged at a position below the opposite surface 23e (on the opposite side of the output shaft 24). Therefore, the triangular shape connecting the three points of the respective fixing holes 11d of the pair of holder body fixing portions 11b and the cutout holes 33b of the body fixing portion 33 is fixed in a horizontal arrangement perpendicular to the direction of the axis L1 of the output shaft 24. In comparison with the straight line, the cutout hole 33b of the vehicle body fixing portion 33 that constitutes one point of the triangle shape is in the direction of the axis L1 of the output shaft 24 with respect to the straight line connecting the fixing holes 11d of the pair of holder vehicle body fixing portions 11b. By disposing the lower portion, the speed reduction portion 22 and the motor main body 21 can be firmly fixed in the direction of the axis L1 of the output shaft 24.

The above embodiment may be modified as follows.
In the above embodiment, the gear housing fixing portion 32 has the three fastening fixing portions 32a penetrating in the plate thickness direction, and passes through the fastening fixing portions 32a and is screwed into the female screw 23d of the gear housing 23. Although it is fixed to the gear housing 23 by the one screw 35, it may be fixed in another configuration.

  For example, you may change as shown in FIGS. The gear housing 41 of this example has a pair of mounting legs 41a that are in contact with the outer peripheral surface of the pipe-shaped frame member 42 as a rod-shaped member over a range of about 180 °. As shown in FIG. 7, one fixed column 41 c that protrudes in the same direction as the direction in which the output shaft 24 protrudes is formed on the surface 41 b of the gear housing 41 from which the output shaft 24 protrudes. The fixed column 41 c is provided on the side opposite to the mounting leg 41 a (on the side opposite to the mounting leg) with respect to the output shaft 24 when viewed from the axial direction of the output shaft 24. The fixed column 41c is formed with a female screw 41d that opens to the tip side.

  And the gear housing fixing | fixed part 44 in the bracket 43 of this example has the fixing piece 44a which can be fixed with respect to the gear housing 41 with the volt | bolt 45 as a fastening member for fixing the gear housing 41 to the frame member 42. Yes. Specifically, the gear housing fixing portion 44 has one fastening fixing portion 44b penetrating in the thickness direction at a position corresponding to the fixing column 41c. The gear housing fixing portion 44 is fixed (supported) to the gear housing 41 by a screw 46 that passes through the fastening fixing portion 44b and is screwed into the female screw 41d. Further, the gear housing fixing portion 44 includes a pair of extending portions 44c extending toward the mounting leg 41a so as to sandwich the output shaft 24, and a curved extension extending from the tip of the extending portion 44c. The fixing piece 44a is in contact with the outer peripheral surface of the frame member 42 over a range of about 135 ° with the member 42 interposed therebetween. Then, as shown in FIG. 8, the bolt 45 passes through the fixed piece 44 a and the frame member 42 and is screwed into the nut 47 accommodated in the nut accommodating portion 41 e of the gear housing 41, so that the gear housing 41 is The fixing piece 44 a is fastened and fixed to the frame member 42 and the gear housing 41 while being fastened and fixed to the frame member 42. Thus, the gear housing fixing portion 32 is supported at three points with respect to the gear housing 41 (frame member 42).

  If it does in this way, compared with what does not have the fixed piece 44a (bracket 31 of the said embodiment), for example, the number of screws can be reduced and an assembly man-hour can be reduced. Further, in this example, the fixing piece 44a also has a function of a washer interposed between the head of the bolt 45 and the frame member 42, and the number of washers is compared with a configuration using a separate washer. Can also be reduced.

  Also, for example, as shown in FIGS. Although not particularly mentioned in the above embodiment and other examples, the gear housing 51 is provided with a rubber support member 52 that can be supported by the vehicle body. As shown in FIG. 10, the rubber support member 52 is made of an elastic body (rubber material), and is fixed to a support column 51 a that is integral with the gear housing 51 (integral molding). The rubber support member 52 (support column 51a) protrudes from the surface on the side opposite to the mounting leg 51b (the side opposite to the mounting leg) for fixing the gear housing 51 to the frame member 42. The rubber support member 52 has a constricted portion 52a having a small diameter at an intermediate portion in the projecting direction. In addition, two fixed columns 51 d that protrude in the same direction as the direction in which the output shaft 24 projects are formed on the surface 51 c of the gear housing 51 on the side from which the output shaft 24 projects. The fixed column 51 d is provided on the side opposite to the attachment leg from the output shaft 24 when viewed from the axial direction of the output shaft 24. The fixed column 51d is formed with a female screw 51e that opens to the tip side.

  The gear housing fixing portion 54 of the bracket 53 of this example is fixed to the gear housing 51 while being partially supported by the rubber support member 52. Specifically, the gear housing fixing portion 54 has a fastening fixing portion 54a penetrating in the thickness direction at a position corresponding to each fixing column 51d. The gear housing fixing portion 54 is fixed (supported) to the gear housing 51 by a screw 55 that passes through the fastening fixing portion 54a and is screwed into the female screw 51e. The gear housing fixing part 54 has a supported part 54 b supported by the rubber support member 52. As shown in FIG. 11, the supported portion 54b has a plane that is perpendicular to the plane having the fastening and fixing portion 54a and that faces the surface on the side opposite to the mounting leg of the gear housing 51. The rubber support member 52 (specifically, the constricted portion 52a) can be inserted from the direction along the surface direction, and has a slit 54c having a width that makes press contact with the rubber support member 52 in a direction orthogonal to the insertable direction. As shown in FIG. 11, the slit 54 c of the present embodiment is opened and cut out on the motor body 21 side when viewed from the protruding direction of the rubber support member 52, and slides the bracket 53 toward the motor body 21 side. Thus, the rubber support member 52 (constricted portion 52a) can be inserted into the slit 54c.

  Further, as shown in FIG. 9, the vehicle body fixing portion 56 of the bracket 53 of this example is connected to the gear housing fixing portion 54 via a connecting portion 57 extending from the supported portion 54b. The connecting portion 57 has a first plane 57a inclined by 90 ° with respect to a plane orthogonal to the axis L1 of the output shaft 24, and starts from the portion below the slit 54c of the supported portion 54b first from the motor body 21 side. And further bent and extended to the side opposite to the attachment leg.

  In this case, since the bracket 53 is partially supported by the rubber support member 52, for example, the number of fastening members (screws 55) for fixing the bracket 53 to the gear housing 51 can be reduced. It becomes possible. For example, when the bracket 53 is supported by the gear housing 51 at three points as in this example, the number of screws 55 can be set to two with one point being supported by the rubber support member 52. Of course, in these examples, for example, by changing the type of the bracket 53, it can be fixed to various vehicle bodies with a small change, and the rubber support member 52 is directly attached to the vehicle body without using the bracket 53. Can also be supported.

  In the above embodiment and other examples, the connecting portions 34 and 57 have the first planes 34a and 57a inclined by 90 ° with respect to the plane orthogonal to the axis L1 of the output shaft 24. For example, the connecting portion may be inclined at another angle (for example, 45 °, 60 °, 80 °, etc.). The closer the inclination of the first planes 34a and 57a is to 90 °, the closer the plate surface direction of the first planes 34a and 57a is to the direction of the axis L1 of the output shaft 24, so the connecting portion is the axis L1 of the output shaft 24. It becomes difficult to bend in the direction, and as a result, the speed reduction part 22 and the motor main body 21 are not easily displaced (vibrated) in the direction along the axis L1 of the output shaft 24.

  In the above embodiment, the vehicle body fixing portion 33 has the second flat surface 33a that is continuous with the first flat surface 34a of the connecting portion 34, and can be fixed to the vehicle body S by the bolt 38 that passes through the second flat surface 33a. However, the present invention is not limited to this, and a vehicle body fixing portion having a plane inclined with respect to the first plane 34a of the connecting portion 34 may be used.

  In the above embodiment, the vehicle body fixing portion 33 is disposed at a position below the surface 23e opposite to the surface 23b on the side where the output shaft 24 protrudes in the gear housing 23 (on the side opposite to the protruding direction of the output shaft 24). However, the present invention is not limited to this. For example, the vehicle body fixing portion may be disposed at a position above the surface 23e opposite to the surface 23b on the side where the output shaft 24 of the gear housing 23 projects. .

  In the above embodiment, the frame members 12 and 42 as the rod-shaped members are hollow pipes, but the present invention is not limited to this, and the frame members having a U-shaped cross section perpendicular to the longitudinal direction may be used. It is good also as a frame member of the cross-sectional shape.
