An object of the present invention is to provide a window regulator handle for an automobile that can prevent the knob from rattling.

Means for Solving the Problems An automobile window regulator handle according to the present invention comprises a handle body having an end portion having a cylindrical portion,
An elastic tongue, which comprises a knob snap-connected to the cylindrical portion of the handle body and elastically contacts the knob, is integrally provided on the cylindrical portion.

Action Since the knob is elastically constantly pressed by the elastic tongue formed on the cylindrical portion of the handle body side, it is possible to prevent the knob from rattling.

Embodiment Hereinafter, an embodiment of an automobile window regulator handle according to the present invention will be described with reference to the drawings.

1 to 3 show a first embodiment of the present invention. The knobs that are gripped and operated have the same shape as shown in FIGS. 10 and 11 and are used in this first embodiment and each of the following embodiments. At the tip portion 11 of the handle main body 10, a tubular cylindrical portion 12 is provided so as to project in a direction substantially perpendicular to the handle shaft. The same portion as the plurality of locking claws 3b shown in FIGS. 10 and 11 is formed on the lower portion of the inner circumference of the cylindrical portion 12 so as to project therefrom. In addition, a pair of elastic tongue pieces 13, 13 facing each other at an angular position of about 180 degrees are formed on the outer peripheral portion of the tip of the cylindrical portion 12.
Protrusions 13a that come into contact with the knobs are provided at the tips of the elastic tongues 13, 13. The elastic tongues 13 are extended by the slits 14 in the circumferential direction, that is, in the horizontal direction perpendicular to the axis, and in alternate directions. Due to this shape, the elastic tongue piece 13 can be elastically bent through the slit 14.

When the knob 4 of FIG. 10 is assembled to the cylindrical portion 12 of the handle body 10 as described above, the knob 4 is dropped to the outside of the cylindrical portion 12. The engaging shaft portion 4b on the knob 4 side is elastically fitted to the inner peripheral surface of the cylindrical portion 12, and the claw 4c at the tip of the locking shaft portion 4b becomes the locking claw 3b on the cylindrical portion 3 side (see FIG. 10). Undercut engagement.

When dropping the knob 4, the engaging shaft portion 4b is located inside the knob 4.
The annular groove 4d around the abutment contacts the elastic tongues 13, 13 of the cylindrical portion 12 from above. That is, the elastic tongue pieces 13, 13 are elastically bent by the pushing-down force at the time of dropping and are pressed in the space by the slits 14, 14. At this moment, as described above, the pawl 4c at the tip of the engaging shaft portion 4b undercuts the locking pawl 3b on the cylindrical portion 12 side. Therefore, the cylindrical portion 12 that is elastically bent
The elastic restoring force of the side elastic tongue piece 13 to return to the original position enhances the engaging force in the lower undercut engaging portion.

On the other hand, FIGS. 4 to 6 show the second embodiment. Also in the case of the second embodiment, the knob shown in FIG. 10 is used. A pair of elastic tongue pieces 15, 15 facing each other are formed at an angular position of 180 degrees in the cylindrical portion 12. This elastic tongue piece 15 is formed by a slit 17 which extends substantially parallel to the axial direction and extends vertically. The tip end portion in the figure is open and elastically bendable, and a convex locking portion 16 is provided at the tip end portion. Is protruding toward the outside.

The operation of the second embodiment is similar to that of the first embodiment.
The knob 4 shown in FIG. 10 is dropped into the cylindrical portion 12. That is, the locking shaft part 4b on the knob 4 side is elastically fitted to the inner peripheral surface of the cylindrical part 12, and the claw 4c at the tip of the locking shaft part 4b is the locking claw 3b of the locking shaft part 4b (see FIG. 10). See) undercut engagement.

When dropping the knob 4, grip 4a (10th
The elastic tongue pieces 15, 15 of the cylindrical portion 12 are pressed against the inner surface by contacting the respective locking portions 16. That is, at this moment, as described above, the tip locking pawl 4c of the engaging shaft portion 4b is locked by the locking pawl 3b on the cylindrical portion 12 side.
Undercut engagement. Therefore, the elastic tongue piece 15 on the side of the cylindrical portion 12 that is bent due to the elasticity restores the original position, that is, the force that presses the grip 4a of the knob 4 from the inside is applied, and the lower undercut The engaging force at the engaging portion is increased.

FIG. 7 is a modification of the second embodiment, in which the direction of the convex locking portion 20 at the tip of the pair of elastic tongues 19 formed through the slit 21 on the side of the cylindrical portion 12 is changed to the axial direction. The structure is made inward, and this time the elastic pressing force by the elastic tongue piece 19 acts on the outer peripheral surface of the engaging shaft portion 4b on the knob 4 side. In this case as well, it is similar to the first and second embodiments.

8 and 9 show the fourth and fifth embodiments. In the case of FIG. 8, a closed slit is formed on the peripheral side surface of the cylindrical portion 12.
In this structure, the closing slit 24 forms the elastic tongue piece 22 downward in the axial direction and the projection 23 is provided at the tip. Further, in the case of FIG. 9, the elastic tongue piece 25 is formed in the closing slit 27 this time with the projection 26 at the tip thereof facing the circumferential direction. With these structures, almost the same operation as that of the first and second embodiments can be obtained.

The present invention is not limited to the above embodiment and can be modified. For example, it is possible to employ various structures for performing snap connection between the handle body and the knob. For example, as disclosed in Japanese Patent Laid-Open No. 51-120523, a structure is formed in which a slit is formed in the coupling shaft of the knob and the knob is snap-coupled to the handle body, or a handle is disclosed in Japanese Utility Model Laid-Open No. 61-98174. An annular protrusion or an annular recess may be formed on the cylindrical portion of the main body.

Effects of the Invention As described above, the window regulator door handle for an automobile according to the present invention can use the knob that has been used before as it is, and the elastic tongue can obtain the elastic pressing force by the slit in the cylindrical portion on the handle body side. By forming the piece, the undercut engagement force between the knob and the cylindrical portion on the handle body side is further increased. Therefore, problems such as backlash due to long-term use are eliminated.
