On the other hand, a motor 52 includes a motor main body 61 and a reduction section 62 for reducing the rotation of the motor main body 61 and outputting the reduced speed.
Consists of FIG. 8 shows the internal structure of the speed reducer 62 of the motor 52. The worm 63 that rotates based on the driving of the motor main body 61 is meshed with a worm wheel 66 that is rotatably supported in a space formed by the synthetic resin gear housing 64 and the cover 65 of the reduction unit 62. . The worm wheel 66 is drivingly connected to an output shaft 68 having an output gear 67 exposed to the outside of the gear housing 64 so as to be integrally rotatable. The output gear 67 meshes with the sector gear 56 of the regulator 51.

The torque of the motor body 61 is transmitted to the sector gear 56 via the worm 63, the worm wheel 66, the output shaft 68 and the output gear 67, and the sector gear 56 rotates about the support shaft 54. The rotation of the sector gear 56 about the support shaft 54 causes the lift arm bracket 59 to move up and down, and a window glass (not shown) attached to the lift arm bracket 59 moves up and down.

[0006]

The motor 52 is fixed to the support base 53 by inserting a plurality of screw screws 69 into the support base 53 and tightening the screw to a gear housing 64 made of synthetic resin. I have.

Here, when the window glass reaches the upper end (end on the closed side) of the window frame or the regulator reaches the lower end (open end), the reaction force is generated by the support base. The force in the direction of rotating the motor 52 itself against the force 53 and the force in the direction of moving the motor 52 itself away from the sector gear 56 (support base 53). That is,
At the time of locking, a force such that the motor 52 and the support base 53 move relatively acts on each other. Therefore, a large load repeatedly acts on the portion of the housing 64 into which the screw screw 69 is screwed.

If the screw screw 69 is directly screwed into the gear housing 64, the above-mentioned load deforms the screw hole of the synthetic resin housing 64, which is a relatively soft material, and the fixing strength of the screw 69 Will decrease. Therefore, conventionally, instead of directly screwing the screw screw 69 into the gear housing 64 made of synthetic resin, a metal column 70 is embedded in the housing 64, and the screw screw 69 is screwed into the metal column 70. Has been adopted. That is, the motor 5
The rigidity of the fixing portion of No. 2 was increased to prevent the fixing strength from decreasing.

However, the metal column 70 is an expensive member specially provided for increasing rigidity, and requires a complicated process of insert molding for embedding the metal column 70 in the gear housing 64. This is one of the factors that increase the cost of the power window device.

The worm 23 that rotates based on the driving of the motor main body 21 is meshed with a worm wheel 26 that is rotatably supported in a space formed by a synthetic resin gear housing 24 and a cover 25 of the reduction unit 22. . The worm wheel 26 has an output gear 27 exposed to the outside of the gear housing 24 and is drivingly connected to an output shaft 28 arranged in a direction orthogonal to the worm 23 so as to be integrally rotatable. This output gear 27 is meshed with the sector gear 16 of the regulator 11.

The torque of the motor body 21 is transmitted to the sector gear 16 via the worm 23, the worm wheel 26, the output shaft 28 and the output gear 27, and the sector gear 16 rotates about the support shaft 14. The rotation of the sector gear 16 about the support shaft 14 causes the lift arm bracket 19 shown in FIG. 1 to move up and down, so that a window glass (not shown) attached to the lift arm bracket 19 moves up and down.

As shown in FIGS. 2 and 3, the gear housing 24 is provided with extensions 24a corresponding to the mounting pieces 13b of the support base 13, respectively. The extension portion 24a is formed with an insertion hole 24b through which the fixing bolt 20 is inserted. The insertion hole 24b extends in parallel with the output shaft 28, that is, in a direction perpendicular to the flat direction of the motor 12 in the present embodiment.

On the other hand, the mounting surface 4 of the mounting board 4
The fixing portion 4b is integrally provided at a position corresponding to the mounting piece 13b of the support base 13 and the extension portion 24a of the gear housing 24. The fixing portion 4b has a screw hole 4c into which the fixing bolt 20 is screwed. The fixing portion 4b is made of the same material as the mounting board 4, that is, a metal material.

The support base 1 of the regulator 11
3 is fixed to the mounting surface 4 a of the mounting board 4, the fixing bolt 20 extends in parallel with the output shaft 28 (in a direction perpendicular to the flat direction of the motor 12) of the mounting piece 13 b of the support base 13 and the extension of the gear housing 24. The insertion hole 13d of the outlet 24a,
24b, and is screwed into the screw hole 4c of the fixing portion 4b. That is, the motor 12 (gear housing 24) is sandwiched between the metal support base 13 and the fixing portion 4b of the metal mounting board 4, and the fixing bolt 20 is fixed between the support base 13 and the fixing portion 4b. Tighten gear housing 24
Is fixed. The motor 12 is fixed so that its flat direction is substantially parallel to the mounting board 4 (the inner panel 3).

In this embodiment, the gear housing 24
An anti-vibration rubber 29 is interposed between and the fixing portion 4b. The anti-vibration rubber 29 suppresses transmission of vibration when the motor 12 is driven to the mounting board 4, that is, the door 1 side.

Here, as described above, when the window glass reaches the upper end (closed end) of the window frame, or when the regulator reaches the lower end (open end), a locked state occurs. The reaction force is a force in a direction of rotating the motor 12 itself against the support base 13 and a force in a direction of moving the motor 12 itself away from the sector gear 16 (support base 13). That is, at the time of locking, a force such that the motor 12 (gear housing 24) and the support base 13 relatively move acts on each other.

In the present embodiment, such a motor 12
Even if a force such that the (gear housing 24) and the support base 13 move relatively acts on the fixed portion of the motor 12, particularly between the fixing bolt 20 and the screw hole 4c of the fixing portion 4b,
Since the fixing portion 4b in which the screw hole 4c is formed is made of metal, there is no possibility that the screw hole 4c is deformed, and the fixing strength of the fixing portion of the motor 12 does not decrease.

In this embodiment, the support base 13
Since the fixing bolt 20 is stretched between the support base 4 and the fixing portion 4b, the above-mentioned force is not concentrated at one place between the support base 53 and the gear housing 64 as in the related art.
It is distributed to the support base 13 and the fixing part 4b. Therefore, high rigidity is not required for the support base 13 and the fixing portion 4b.

As described above, the present embodiment has the following effects. (1) In the present embodiment, the resin-made housing 24 of the motor 12 is sandwiched between the support base 13 of the regulator 11 and the mounting board 4 (fixed portion 4b) of the inner panel 3, and is inserted into the insertion hole 24b of the housing 24. The bolt 20 is inserted into the support base 13 and the mounting board 4 so that the fixing bolt 20 is inserted therethrough.
The motor 12 (resin housing 24) is fixed by tightening between the fixing portion 4b and the fixing portion 4b. Therefore, even if a force that causes the motor 12 and the support base 13 to move relative to each other acts on each other, the fixing bolt 20 is not used.
And the fixing portion 4b of the mounting board 4 are fastened between the metal members, so that there is no possibility that the fastening portion (fixed portion) is deformed. Therefore, it is possible to prevent the fixing strength of the fixed portion of the motor 12 from decreasing. Moreover, the motor 12
Since the (resin housing 24) is clamped between the support base 13 and the fixing portion 4b of the mounting board 4 and tightened with the bolt 20, no special parts are required. or,
Since the metal column 70 used in the related art does not need to be used, the number of metal parts assembled to the resin gear housing 24 can be reduced. Therefore, when the gear housing 24 is recycled, the gear housing 24 is easily separated for each material, and the recyclability can be improved.

(2) In the present embodiment, since the fixing bolt 20 is stretched between the support base 13 and the fixing portion 4b, the above-mentioned force is dispersed between the support base 13 and the fixing portion 4b. Therefore, high rigidity is not required for the support base 13 and the fixing portion 4b, and the portion can be formed at low cost.

(3) In the present embodiment, the vibration isolating rubber 29 is interposed between the housing 24 and the fixed portion 4b. Therefore, it is possible to suppress the transmission of the vibration when the motor 12 is driven to the mounting board 4, that is, the door 1 side. Therefore, quietness in the vehicle compartment can be improved.

(4) In the present embodiment, a bolt 20 is used as a fastening member, and a screw hole 4c for screwing the bolt 20 into a member on the side opposite to the insertion side of the bolt 20, ie, the fixing portion 4b.
Was integrally formed. Therefore, since the bolts 20 are merely tightened, the mounting work of the motor 12 is easy.

(5) In the present embodiment, the motor 12 is fixed so that its flat direction is substantially parallel to the mounting board 4 (the inner panel 3). Therefore, the mounting board 4
The protrusion of the motor 12 in a direction orthogonal to the (inner panel 3) can be suppressed as small as possible.

The embodiment of the present invention may be modified as follows. In the above embodiment, the motor 12 (the resin housing 2
4) was held between the support base 13 and the fixing portion 4b of the mounting board 4 and the motor 12 was fixed by tightening with the bolt 20, but the present invention is not limited to this fixing structure, and may be changed as appropriate. . For example, as shown in FIGS. 4 and 5.

3b is formed into a substantially U-shape with an extension piece 13e integrally formed so as to sandwich the extension portion 24a of the gear housing 24, and the extension portion 2e is formed at the extension piece 13e.
A screw hole 13f is formed at a position corresponding to the insertion hole 24b of 4a. Then, the fixing bolt 20 is inserted into the mounting piece 13b of the support base 13 and the insertion holes 13d and 24b of the extension part 24a of the gear housing 24, and the screw hole 1 of the extension piece 13e is formed.
The motor 12 (the resin housing 24) may be fixed to the support base 13 by screwing it to 3f. The support base 13 is provided with four mounting pieces 13a for fixing to the mounting board 4, and is fixed to the mounting board 4 with the four mounting pieces 13a.

Even in this case, similar to the above embodiment,
Even if a force that causes the motor 12 and the support base 13 to move relative to each other acts on each other, the fixing bolt 20 keeps the support base 1
Since the metal member 3 and the extension piece 13e are fastened between the metal members, there is no possibility that the fastening portion (fixed portion) is deformed. Therefore, it is possible to prevent the fixing strength of the fixed portion of the motor 12 from decreasing. Moreover, the motor 12 (housing made of resin) is clamped between the support base 13 and the extension piece 13e formed integrally with the support base 13 and fastened with the bolt 20, so that a special bolt is used. No parts are required.

As shown in FIG. 6, the extension piece 13e
The screw hole 13f provided in the above may be a through hole 13g, and the nut 30 for screwing the bolt 20 to the extension piece 13e may be integrally fixed.

In the above embodiment, the fixing bolt 20 is
Support base 13 and motor 12 (resin housing 2
4) is inserted and screwed to the mounting board 4. However, the mounting direction of the fixing bolt 20 is not limited to this. For example, conversely, fixing bolt 20
Mounting board 4 and motor 12 (resin housing 24)
May be inserted and screwed to the support base 13. In this case, an insertion hole for inserting the fixing bolt 20 is formed in the mounting board 4, and a screw hole for screwing the bolt 20 is formed in the support base 13.

When the fixing bolt 20 is mounted in such a mounting direction, the inner panel in which the mounting board 4 is formed integrally with the inner panel 3, that is, the power window device 1 is used.
The present invention can also be applied to a door having an inner panel provided with a mounting portion for mounting 0. Specifically, an insertion opening for inserting the power window device 10 into the space between the inner panel and the outer panel is formed in the inner panel, and the power window device 10 is inserted into the space from the insertion opening. Then, the fixing bolt 20 is screwed to the support base 13 by inserting the fixing bolt 20 through the inner panel and the motor 12 (the resin housing 24).

In the above embodiment, the fixing bolt 20 is used as the fastening member, but other fastening members other than the bolt 20 may be used. In the above embodiment, the vibration isolating rubber 29 made of a rubber material is used as the vibration isolating member interposed between the housing 24 and the fixed portion 4b. However, the vibration isolating member other than the rubber material, for example, the vibration isolating of the resin material is used. A member may be used. Also, it may be omitted.

The configurations of the motor 12 and the regulator 11 in the above embodiment may be changed as appropriate. Incidentally, the regulator 11 is an X-arm type window regulator, but may be a well-known wire type window regulator.
