Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an automobile door, and particularly to an automobile door structure in which a step between the outer surface of the door glass and the outer surface of the door sash is eliminated so that the door sash becomes a road surface.

(Prior Art) As a means of reducing air resistance and wind noise while driving and improving the appearance, it is known that a vehicle has a so-called flush surface, with the outer surface of the vehicle body facing the road surface.

For example, as described in Japanese Utility Model Application No. 60-164424, a door glass guide mechanism is arranged offset inward from the door glass, and the door glass guide mechanism is located at the upper and lower ends of the front and rear edges of the door glass. Consists of a fixed slider, a tip of the slider that is offset from the door glass and protrudes toward the vehicle interior, and a guide groove with a substantially U-shaped cross section that guides the tip slidably in the vertical direction. Some sliders are equipped with a continuous integral guide portion in which the weather strip extends into the guide groove and slides on both the inner and outer surfaces of the tip of the slider.

(Problem to be Solved by the Invention) However, in the structure as described above, the tip of the slider only fits into the guide part, so when the door glass is raised or lowered, the door glass moves in the longitudinal direction of the vehicle body. There is a risk of rocking and rattling, and if the tip of the slider and the guide portion are not deeply fitted, the tip of the slider may separate from the guide portion and the door glass may become unable to move up and down.

The present invention has been made in view of the above points, and an object of the present invention is to provide a door structure for an automobile that can prevent the door glass from wobbling in the longitudinal and lateral directions of the vehicle body when the door glass is raised and lowered.

(Means for Solving the Problems) The configuration of the present invention for achieving the above object will be explained with reference to FIG. 4 corresponding to the embodiment.

A door sash 3 is provided on the upper part of the door panel 2, and a door glass 4 is disposed on the outside of the door sash 3 so as to be movable up and down. A slider 11 (10, 12) having a roller is provided near the front edge or rear edge of the door glass 4,
A garnish attachment part that opens toward the center of the door glass is provided on the interior side of the door sash, and a roller of the slider 11 is provided adjacent to the garnish attachment part on the interior side of the door sash. A guide portion is provided that guides the roller 23 and restricts movement of the roller 23 back and forth and left and right.

(Function) Even if the door glass 4 tries to swing in the front-back direction or left-right direction of the vehicle body when the door glass 4 is raised or lowered, the swing is restricted by the roller 23 being guided by the guide part, and the backlash of the door glass 4 is prevented. Sticking is prevented.
