Subsequently, the mounting operation is easily completed by attaching the speed reduction portion 41 of the drive mechanism 27 to the first attachment portion 31 in a state where the output shaft 45 of the drive mechanism 27 is aligned with the shaft hole 49 of the drum 17. Become like

FIGS. 4 to 12 show an embodiment in which the base member 25 is mounted on a door panel as a fixed body. Note that the same components as those in the above-described embodiment are denoted by the same reference numerals.

The window regulator device 1 of this embodiment has a guide rail 3, a carrier plate 5 that can move up and down along the guide rail 3, a wire 7 that moves the carrier plate 5 up and down, and a drive that pulls and controls the wire 7. And a unit 9.

The guide rail 3 rises from both sides of the rail body, and is formed into a curl-shaped left and right rail portion 11, 1.
The guides 13 and 14 for guiding the wire 7 are provided at both upper and lower ends, respectively, and are attached to an inner panel (not shown) of the door via a bracket 15. Will be able to

The wire 7 is fed out from the outer peripheral surface of the drum 17 at the time of normal rotation, for example, passes from the upper guide 13 to the rail 11 and passes through the lower guide 14. The winding is wound around the drum 17 through the intermediary. Therefore, when the drum 17 is reversed,
The wire 7 going from the drum 17 to the lower guide member 14 side is the feeding side. The wire 7 from the upper guide 13 to the drum 17 is the winding side. The outer guide is provided from the upper and lower guides 13 and 14 to a plug locking portion 55 provided on the base member 25, which will be described later. The tubes 51, 51 pass through.

As shown in FIG. 7, extension tubes 5 for absorbing slack of the wires 7 are provided on the outer tubes 51, 51.
2 is provided, and a peripheral groove 54 of the plug 53 is engaged with a plug locking portion 55.

The carrier plate 5 includes left and right mounting portions 21 and 21 to which the window panel 19 is mounted, and a wire locking and holding portion 23 which is coupled to the rails 11 and the wires 7 arranged between the rails 11. Guide rail 3
Are slidably mounted up and down with respect to the rail portion 11.

The drive section 9 has a base member 25, a drive mechanism 27 such as a drive motor, and a drum 17. The base portion 25 is made of metal, and has a plug locking portion 55 for locking the plug 53 of the outer tube 51, and a driving mechanism 27.
A first mounting portion 57 for mounting the vehicle, and a second mounting portion 57 for mounting on the vehicle body side.
, And a plurality of bendable holding portions 61, the plug locking portion 55, the first and second mounting portions 57, 5.
9. The holding portion 61 is integrally press-formed.

The first mounting portion 57 is formed in a planar shape.
A cylindrical drum supporting portion 63 that fits with the fitting concave portion 47 provided on the upper surface side of the drum 17 is provided at the substantially central central flat portion 57 a, while being bent along the outer peripheral surface of the drum 17. The holding parts 61 are vertically provided at three places.

The holding portion 63 is bent approximately 90 degrees inward and temporarily supports the lower surface of the drum 17. Thus, the case portion 65 that surrounds the upper surface and the outer peripheral surface of the drum 17 is formed by the three holding portions 61 and the central flat portion 57a of the first mounting portion 57.

The first mounting portion 57 has a drive mechanism 2
7 are mounted by mounting screws 67.

The speed reducer 41 comprises a worm and a worm wheel (both not shown), and a rectangular cylindrical output shaft 45 provided on the worm wheel protrudes from the upper surface of the speed reducer 41.

The second mounting portion 59 has a shape that extends downward from the first mounting portion 57 and is then bent outward shortly. Screws or the like are attached to the door inner panel or the like on the fixed body side. Means can be integrally attached.

As shown in FIG. 6, the plug locking portion 55 protrudes from the flat end of the first mounting portion 57, and has a vertically long engagement groove 71 which is open on the lower side on the locking surface 69 side. ing.

The locking surface 69 has upper and lower guide portions 13 and 14.
The engaging groove 71 has a length substantially corresponding to the vertical dimension of the outer peripheral surface of the drum 17. The circumferential groove 54 of the plug 53 is slidably engaged with the engaging groove 71, and the engaging groove 7
The first opening is closed after the assembly of the plug 53 is completed, so that it does not fall out.

The drum 17 is provided with the fitting recess 47 on the upper surface side as described above, and the shaft hole 49 in the form of a square tube which is integrally engaged with the output shaft 45 of the speed reducer 41 on the lower surface side. .

For example, when the upper half of the outer peripheral surface of the drum 17 is a payout surface for feeding out the wire 7, the lower half is
, And the feeding surface and the winding surface are alternately switched at the time of normal rotation and at the time of reversal.

Therefore, according to this embodiment, the first and second mounting portions 57 and 59 and the holding portion 61
The following functions and effects are obtained in addition to the same functions and effects as those of the first embodiment.

That is, as shown in FIG. 11, when the vehicle is actually mounted, the outer tube 51 is in an almost S-shaped state. When the wire 7 is excessively wound during the full open and full close constraints, the outer tube 51 approaches a linear state as shown in FIG. 12, and the plug 53 receives a load in a form lifted in the X direction.

At the same time, since the outer tube 51 becomes straight, the extension spring 52 comes into close contact with the outer tube 51 and further exceeds the maximum stroke of the extension spring 52, so that a load is generated in the plug 53 in the Y direction. The load in the X and Y directions causes a deformation action on the base member 25,
At this time, as shown in FIG. 12, due to the combined force F in the X and Y directions, the plug 53 is substantially in a straight line with the wire 7 fed from the outer peripheral surface of the drum 17 in the locking groove 71 as shown in FIGS. The load applied to the base member 25 is reduced since the base member 25 moves and escapes, so that there is an advantage that the deformation of the base member 25 can be reliably suppressed.

[0047]

As described above, according to the present invention, the base member has a first mounting portion for mounting the drive mechanism, a second mounting portion for mounting on the fixed body side, and a case surrounding the drum. Since the unit and the holding unit for temporarily supporting the drum are provided integrally,
Since the number of parts is reduced, workability, cost, and assemblability are extremely excellent, including man-hours for parts management.
