DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a side door frame mounting structure for an automobile. More specifically, the present invention relates to a mounting structure in which a lower frame of a door is inserted and connected to an upper frame.

[Prior Art] As a door frame of this type, a door upper frame mounted on an upper portion of a door main body including a door outer panel and a door inner panel connected to the door outer panel, and an upper end portion of the door upper frame provided in the door main body. There is a lower door frame that is connected to the lower end of the door glass to guide the door glass together with the door upper frame so that the door glass can move up and down. An enlarged portion into which the upper end portion of the door lower frame can be loosely inserted is formed at the lower end portion of the door upper frame, and an inclined portion that further widens toward the inner panel is formed at the enlarged portion on the inner panel side.

Conventionally, in order to mount the door upper frame and the door lower frame, first, the door upper frame is attached to the upper part of the door body, and then the upper end portion (2a) of the door lower frame 2 is attached to the door upper frame 1 as shown in FIG. It is inserted into the enlarged portion 1a in a state of being inclined within the inclination angle of the inclined portion 1b. Then, the upper frame 2a of the lower frame 2 is pressed against the shoulder 1c of the enlarged portion 1a while the lower frame 2 is being vertically assembled to assemble the lower frame 2 to prevent the upper frame 2a from rattling.

However, since the shoulder portion 1c of the upper frame 1 is inclined, when the size of the upper frame 1 or the lower frame 2 varies, or when an assembly error occurs in these parts, the lower frame 2 The upper end 2a of the lower part of the lower frame 2 when the door is opened and closed when the upper end 2a of the lower part is separated from the shoulder 1c
There was a problem that 2a rattles in the enlarged portion 1a and produces an abnormal noise.

In order to eliminate this point, a bracket structure for lower sash has been proposed in which a bracket is fixed to the upper end of the lower sash, and a plurality of beads are provided in the portion that receives the lower end of the door sash in the vertical portion of the bracket (actual flat plate). 2-71
023). According to this structure, the bracket contacts the lower end of the door sash at the apex of the bead and can be securely held by the bead. As a result, it is possible to prevent the generation of abnormal noise due to variation in size or assembly error.

[Problems to be Solved by the Invention] However, in the above bracket structure for lower sash, since the bracket is provided, the number of parts is increased, which causes a problem of increasing cost. Further, one of the beads provided on the bracket needs to be provided at least in the longitudinal direction, and the lower end of the door sash must be inserted in parallel with the bead in the range where the bead is provided, which deteriorates workability. There was still a problem that had to be solved.

The object of the present invention is to firmly attach the door lower frame to the door upper frame even if there is an error in the dimensions and assembly of the door frame parts, and to prevent the generation of noise when the door is opened and closed. An object is to provide a mounting structure for an automobile door frame that can be easily assembled.
