In such an elevating device, a sliding member for holding a window glass is slidably guided on a guide rail extending linearly in a substantially vertical direction, and the guide member is slidably guided through a wire connected to the sliding member. The configuration is such that the window glass slides along the guide rail together with the sliding body. The wire is positioned between the upper and lower guide rollers so as to be located outside the guide rail and along the guide rail.

[0004]

By the way, in recent years, in a windshield elevating device for an automobile, a guide rail is three-dimensionally curved to draw a three-dimensional trajectory in accordance with a design requirement of the vehicle. The window glass is being moved up and down so that

[0005] However, in the above-described conventional wire-driven lifting device, when the guide rail is curved three-dimensionally, simply passing the wire between the upper and lower guide rollers causes the wire to extend along the outside of the guide rail. Since the degree of tension of the wire changes depending on the sliding position of the sliding body, there is a possibility that smooth lifting and lowering of the window glass may be hindered. Further, in order for the wire to extend along the outside of the guide rail, for example, the wire must be guided by a plurality of guide parts scattered along the guide rail, and the arrangement position and shape of the plurality of guide parts Must be changed according to the curved shape of the guide rail and the like.

SUMMARY OF THE INVENTION An object of the present invention is to provide a window glass which can easily arrange wires along guide rails of various shapes without using special guide parts, and realizes a smooth lifting and lowering of the window glass. To provide a lifting device.

According to the present invention, there is provided a window glass elevating / lowering apparatus, wherein a sliding member is slidably guided by a guide rail, the window glass is held by the sliding member, and a wire connected to the sliding member. A window glass elevating device that slides the sliding body along the guide rail through the guide rail, wherein a groove-shaped space that extends in the longitudinal direction of the guide rail and guides the wire is provided inside the guide rail. A guide wall portion is formed in the opening of the groove-shaped space so as to extend in a direction to narrow the opening.

[0008]

According to the window glass elevating and lowering device of the present invention, a groove-like space for guiding a wire for driving the sliding member is defined inside a guide rail for slidably guiding the sliding member. By forming a guide wall portion extending in a direction to narrow the opening in the opening of the defined groove-shaped space, the wire can be guided without using a special guide part, and the vicinity of the wire can be guided. The grooved space is narrowed to form a guide surface at the position, the displacement of the wire is suppressed to a small extent, and the opening of the grooved space is narrowed, so that a wide variety of wires around the wire can be formed. The displacement in various directions. As a result, the displacement of the wire is kept small irrespective of the complicated shape of the guide rail, and the smooth lifting and lowering of the window glass is realized.

It is formed in an annular shape that can be fitted between 1M and 41N. An annular claw portion 43A extending along the circumferential direction is formed on the outer peripheral surface on the lower side in FIG. 3 of the third component 43, and the claw portion 43A is a claw of the first component 41. The third component 43 is prevented from slipping over the portion 41P from above in FIG. 3 to engaging with the claw portion 41P. The upper surface portion 43B of the third component 43 is a sliding contact surface with the upper guide surface portions 13G and 13H of the guide rail 13. Then, when the first component 41 is fitted, the second component 42 is compressed in the vertical direction, and the elastic restoring force causes the upper surface portion 43B of the third component 43 to press against the upper guide wall portions 13G, 13H. ing. The annular projection 42A of the second component 42 is provided with the claw 43A of the third component 43.
The portion is pressed radially outward.

Thus, although the wire 3 located inside the third guide rail 13 has its connection portion with the connection block 7 kept at the fixed position P in FIGS. 3 and 6 in the guide rail 13, The portion away from the connection block 7 is displaced in a predetermined direction inside the guide rail 13 according to the curved shape of the guide rail 13 and the sliding position of the sliding body 30. In this example, wire 3
Is displaced in the direction of the arrow in FIG. 6, and the guide wall 13A of the guide rail 13, the left guide surface 13C, the upper and lower guide surfaces 13D, 13E,
And the corner portions C1, C2, C3 between the portions
, The wire 3 is guided, and large displacement of the wire 3 is prevented. Therefore, those portions serve as a wire guide surface for guiding the wire 3, and the sliding body 3
0 regardless of the sliding position of 0
The wire 3 is guided so as to follow the wire 3 so that the window glass G can be smoothly moved up and down.

Such a wire guide surface can be set to an optimum position and size in consideration of the direction of displacement of the wire 3 corresponding to the curved shape of the guide rail 13. For example, the two-dot chain line in FIG. The guide wall 13A is further protruded upward as shown by the arrow to increase the wire guide surface formed thereby, or a guide wall is provided as shown by the reference numeral 13J in FIG. A wire guide surface for guiding the wire 3 displaced in the upper right direction may be newly formed. By the way, the guide surface 1
3C, 13D, 13E and guide walls 13A, 13J
Defines a groove-like space extending in the longitudinal direction of the guide rail 13 and guiding the wire 3. Further, when the guide wall 13A extends upward in FIG. 6 and the guide wall 13J extends downward in FIG. 6, the opening of the groove-shaped space is narrowed. In this manner, as a result of the opening of the groove-shaped space for guiding the wire 3 being narrowed, displacement of the wire 3 in various directions is prevented over a wide area around the wire 3, and the displacement is reliably prevented. I will guide you. Further, since the groove-shaped space for guiding the wire 3 is defined inside the guide rail 13, the groove-shaped space can be formed narrow in order to position the wire guide surface near the position P. As a result, the displacement of the wire 3 can be kept small.

In the case of this embodiment, the third sliding member 4
Since the connection block 7 of the wire 3 is directly connected to the carrier plate 2, the transmission loss of the driving force from the wire 3 is reduced and the sliding force is reduced as compared with a general case where the connection block 7 is connected to the carrier plate 2. When the moving body 40 descends and comes into contact with the stopper 10 (see FIG. 1), no deformation force is generated on the carrier plate 2, and a connection space with the connection block 7 is secured on the carrier plate 2. There is no need.
