It is characterized by the fact that it has been installed.

Operation As described above, the door stop surface between the transition end of the main sash to the lower sash and the upper end of the front edge door contact surface of the door panel is formed by a synthetic resin cover. By positioning the connection point of the door stop surface of the cover to the top end of the door panel further forward than in conventional structures, the base of the front pillar can be made thinner than in conventional structures, and by omitting the main sash that forms one side of the triangular space, the main sash It is possible to save materials, reduce costs, and reduce the weight of the door.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 3.

Basically, as shown in FIG. 3, the present invention omits the part of the main suspension 1 in front of the joint with the lower chassis 2 (that is, the area indicated by the symbol Y in FIG. 4), and the lower chassis 2 is omitted. A reinforcement member 3 for attaching a door mirror is fixed to the upper front surface of the door mirror, and the lower part of the reinforcement member 3 is joined and fixed to the door panel inner 5a, and a door stop that extends almost flush with the front edge door contact surface of the main sash 1 is provided. A cover 4 made of integrally molded synthetic resin and having a surface 4a and covering the reinforcement 3 is fitted and fixed to the lower chassis 2.

More specifically, as shown in FIGS. 1 and 2, the front end of the main sash 1 is bent into a dogleg shape and continues to the lower sash 2, and the front end of the main sash 1, the door panel inner 5a, and the door panel outer A triangular space in which the main sash 1 does not exist is formed between the front edge door contact surface 5c and the upper end of the door panel 5 constituted by the door panel 5b.

The reinforcement 3 includes a door mirror mounting surface 3a to which the base end of the door mirror 6 is joined and fixed by a mounting fixture such as a screw 7, and a lower assembly 2.
a mounting surface 3b to the lower assembly which is joined to the front surface of the door mirror and fixed by spot welding or the like; and a door panel inner which extends downward from the door mirror mounting surface 3a and is joined to the door panel inner 5a within the door panel 5 and is fixed by spot welding or the like. By joining and fixing the mounting surface 3b to the lower assembly and the mounting surface 3c to the door panel inner to the front surface of the lower chassis and the door panel inner, respectively, the reinforcement 3 has a mounting surface 3c to which the door mirror mounting surface 3a is mounted. It is installed so as to be located in a triangular space in front of the upper part of the lower chassis 2.

The cover 4 has a door stop surface 4a that is substantially flush with the front edge door contact surface 1a of the main sash 1, covers the door mirror mounting surface 3a of the reinforcement 3, and has a door panel 5 of the lower sash 2 on the rear edge.
For example, it has a shape that has an attachment part 4b to the lower assembly that is fitted and fixed to a part that protrudes upward from the upper edge.
It is constructed by integral molding of synthetic resin such as ABS resin, and by fitting and fixing the cover 4 to the lower sash 2, the door stop surface 4a of the cover 4 is aligned with the front edge door contact surface 1a of the main sash 1 and in front of the door panel 5. The cover 4 has a structure in which the front edge door contact surface 5c of the main sash 1 is connected to the front edge door contact surface 5c by a surface that is substantially flush with the front edge door contact surface 1a, and the cover 4 fills a triangular space in front of the upper part of the lower chassis 2. It is.

In the cover 4, a window hole 4c for attaching a door mirror and a working hole 4d are formed on the outer and inner surfaces of the cover 4, respectively, at positions facing the door mirror attaching surface 3a of the reinforcement 3. Insert end 6a and reinforcement 3
After fixing the door mirror 6 to the door mirror mounting surface 3a of the reinforcement 3 by screwing the screw 7 through the working hole 4d, the working hole 4d is closed by fitting the grommet 8. In addition, the weather strip 9 attached to the front edge door contact surface 1a of the main sash 1 is continuously attached to the door contact surface 4a of the cover 4.
The weather strip 9 comes into elastic contact with the front pillar 11 to provide a water seal when the door is closed. It goes without saying that a weather strip is also attached to the front edge contact surface of the door panel 5.

In FIG. 2, 12 indicates a fender, and 13 indicates a door glass.
