[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, the basic structure of a window regulator device is the same as that described in the prior art. That is, the base end of the lift arm 1 is connected to a rotating shaft 5 erected on a bracket 5 of a door inner panel (not shown).
The arm portion of the lift arm 1 is provided with an arcuate sector gear 11. A pinion (not shown) driven by an electric motor or the like meshes with the sector gear, and the lift arm 1 Can be turned up and down around the center.

A roller 12 is mounted on the tip of the lift arm 1, and the roller 12 is opened in the vehicle direction C
It is located in a rail 2 having a U-shaped section. The roller 12 is prevented from escaping from the rail 2 by a stopper (not shown).
The rail 2 is suspended by the rollers 12 and is located in a substantially vertical posture. At both ends of the suspended rail 2, mounting holes 21 are provided, and at one end of the rail 2, an operation piece 3 is provided. As shown in FIGS. 2 and 3, the operating piece 3 has a guide portion 33 that extends substantially parallel to the lower surface of the rail 2 toward the door outer panel (to the left in FIG. 3), and stands upright on a side edge of the guide portion 33. And a mounting portion 34 extending further from one end of the flange portion 31. The mounting portion 34 is fixed to the back surface of the rail 2. The distal end of the operation piece 3 protrudes in the longitudinal direction from the end of the rail 2, bends obliquely away from the rail 2, and gradually widens toward the distal end toward the door inner panel (to the right in FIG. 3). Is a contact surface 32 that spreads. The mounting hole 21 (FIG. 2) of the rail 2 has an oval shape extending in the longitudinal direction, and as shown in FIG.
An engagement piece 22 is provided at an intermediate position in the longitudinal direction of the rail 2. As shown in FIG. 6, the engagement piece 22 is formed by bending a long plate body in a stepped manner, and the lower half 221 is fixed to the back surface of the rail 2, and the upper half 222 is separated from the lower half 221 by the rail 2.
And protrudes from the upper surface of the rail 2 at a position offset to the side.

In FIG. 1, a glass receiving member 4 is provided at the center of the lower edge of the window glass W, which is bent in a U-shape and attached to the lower edge of the glass as shown in FIG. At the same time, mounting pieces 41 (only one is shown) that protrude downward are provided on the side surfaces of both ends.
Has a mounting hole 411 provided with a weld nut 42 behind it.
Is provided.

When the window glass W is attached to the rail 2, as shown in FIG. 1, the window glass W is inserted between the opening of the door outer panel P and a door inner panel (not shown) (arrow in FIG. 1). 2), the glass receiving member 4 provided on the lower edge thereof comes into contact with the contact surface 32 of the operation piece 3 as shown by an arrow in FIG. As a result, a turning force acts on the rail 2 about the rotation shaft 121 of the roller 12, and the rail 2 is rotated in the horizontal direction about the rotation shaft 121 (arrow in FIG. 2). The state shown in FIG. At this time, since the contact surface 32 of the operation piece 3 has a shape that spreads to the door outer panel side and the door inner panel side, the glass receiving member 4 surely comes into contact with the contact surface 32. In this state, the rail 2 rotates from the horizontal posture to a slightly inclined position, and the glass receiving member 4 is in contact with the upper surface of the end of the rail 2.

Therefore, when the window glass W is further pushed in, the rail 2 is directly pushed by the glass receiving member 4, and
As shown in FIG. 5, the glass receiving member 4 is rotated to a substantially horizontal position along the bottom surface, and the glass receiving member is placed on the rail 2. The position of the glass receiving member 4 is regulated by the lift arm 1 and the engagement piece 22 without falling off the rail 2. In this state, the position of the rail 2 is adjusted in the horizontal direction, and the glass receiving member 4 is passed through the mounting hole 21 of the rail 2.
Bolt 4 into the weld nut 42 of the mounting piece 41
3 is screwed and fixed (FIG. 6). In these operations, since the glass receiving member 4 is positioned by the lift arm 1 and the engagement piece 22 so as not to fall off the rail 2, the window glass W is held by one hand from above as in the conventional case. You don't have to do that. Therefore, the assembling work becomes extremely easy.

The provision of the engagement piece 22 reliably prevents the glass receiving member 4 from falling off as described above, but is not always necessary.
