2. Description of the Related Art Among automobiles, a vehicle having a door called a so-called full door in which a door sash is press-molded integrally with a door body is used as a door sash such as a roll-formed sash in a general sash door. Since the door weather strip holding portion cannot be formed, a retainer is mounted on the door sash, and the door weather strip is mounted on the outer periphery of the door sash via the retainer. This will be described more specifically with reference to FIGS.
Is a door body, 2 is a door sash press-molded integrally with the door body 1, and a front sash inclined side 2A,
Upper sash upper side 2B and rear sash vertical side 2
C.

[0003] A shelf 3 is provided on the outer periphery of the door sash 2 on the passenger compartment side.
And a first retainer 4A is fixed on the shelf 3 extending from the sash inclined side 2A to the sash upper side 2B by spot welding or the like.
A second retainer 4B is similarly fixed on the shelf 3 of C.

A first retainer 4A and a second retainer 4B
Are formed in a substantially L-shaped cross section by the bottom wall 5 and the rising wall 6, and the edge of the bottom wall 5 and the edge of the rising wall 6 hold the edge of the base portion 12 of the door weather strip 11. The holders 7 and 8 to be formed are bent. These first and second retainers 4A and 4B overlap the bottom wall 5 on the shelf 3, and the rising wall 6 overlaps the sash vertical wall 9 connected to the shelf 3, and The sash is overlapped at the corner with the vertical wall 9.

[0005] A sealing material 10 is applied to a parting part between the holder part 8 of each of the first and second retainers 4A and 4B on the side of the rising wall 6 and the sash vertical wall 9, and the parting part is removed from the parting part. Prevents water from entering.
Further, this sealing material 10 is used for the first and second retainers 4.
A part of the bottom wall 5 at the end of A, 4B and the parting part of the shelf 3 and a parting part of the rising wall 6 and the sash vertical wall 9 are additionally coated. In the portion, the sealing material 10 is formed so that a gap due to a step does not occur between the sealing material 10 and the door weather strip 11.
Is corrected smoothly.

[0006] The door weather strip 11 is
The base portion 12 is connected to these first and second retainers 4A,
It is elastically engaged with the holder portions 7 and 8 of the door sash 4B and is mounted on the outer periphery of the door sash 2 via the first and second retainers 4A and 4B. At the corner between the sash upper side 2B and the sash vertical side 2C of the door sash 2, the first and second retainers 4A and 4B are discontinuous. It is firmly fixed to the shelf 3 by a clip (not shown). This similar structure is disclosed, for example, in Japanese Utility Model Laid-Open No. 54-56813.

[0007]

The above-mentioned sealing material 1
0 is generally applied using a flat brush so as not to make the coating amount excessive, but in particular, the upper side of the sash 2
In part B, since the first retainer 4A exists substantially horizontally and is a toe on the shelf 3, it is applied to the parting part between the holder part 8 and the sash vertical wall 9. The sealing material 10 may hang down from the terminal end of the holder portion 8 and solidify in a protruding shape. When the door weather strip 11 is fitted as it is, the protrusion 10a of the sealing material 10 causes the door weather strip 11 There is a possibility that a gap may be formed between the base portion 12 and the base member 12, resulting in poor sealing. Therefore, when the sealing material 10 hangs from the stop end of the holder portion 8 in a protruding manner, the sealing material 10 is wiped off with the flat brush used for the application work, but since the holder portion 8 is at an angle. It is difficult to insert the flat brush into the inside of the holder portion 8, and it becomes difficult to sufficiently wipe off the sealing material 10a hanging down in a protruding manner.

For this reason, an attempt has been made to cut the end of the holder portion 8 obliquely from the bent base of the stop end so as to facilitate insertion of a sealing material scraping tool such as a flat brush. It was, on the contrary, sealing material 1
This causes new problems such as an increase in the amount of dripping of 0 and burrs on the cut surface, which makes it impossible to smoothly scrape off the sealing material by the above-mentioned tool without considerable skill. Therefore, the present invention provides a door weather strip mounting portion structure that can easily wipe off a sealing material that hangs in a protruding form from a holder terminal end and can properly mount a door weather strip to a retainer. It is.

[0009]

A first retainer is fixedly formed on a shelf extending from the sash inclined side to the upper side of the sash of the door sash. , the second and the retainer, formed then Tomo the approximately L-shaped cross section with a bottom wall which is bent forming a holder portion to each end edge a rising wall which is fixed to the ledge of the sash vertical side
The jaws are attached to the holder on the rising wall side of these retainers.
And a first and a second retainer are respectively positioned and arranged at corners of the shelf and a sash vertical wall connected to the shelf, and a holder of the rising wall is provided. A sealing material is applied to the parting part between the part and the sash vertical wall, and a door weather is applied to the jaws of the first and second retainers.
It engages the engagement groove of chromatography strips, and the base portion of the door weather strip thereto retainer was fitted respectively
In consisting structure, the first end of the jaws of the retainer arranged on the shelf portion of the sash upper, is formed a notch in an appropriate length from the stop terminal of it.

[0010]

The sealing material holding width is left at the end of the holder portion having the cutout portion, so that the sealing material applied thereon does not hang down to the cutout side. When the sealing material hangs down from the terminal end of the holder portion in a protruding manner, the tool can be easily inserted into the inside of the holder portion from the cutout portion, so that the hanging sealing material can be wiped off smoothly.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below, taking a front door as an example and assigning the same reference numerals to the same parts as those in the above-mentioned conventional structure.

In FIGS. 1 to 3, a shelf 3 is formed on the outer periphery of the door sash 2 on the passenger compartment side, and a first shelf 3 is provided on the shelf 3 extending from the sash inclined side 2A to the sash upper side 2B. A point that the retainer 4A is spot-joined, and a second retainer 4B is spot-joined on the shelf 3 of the sash vertical side 2C. The first retainer 4A and the second retainer 4
B has a bottom wall 5 and a rising wall 6 each having a substantially L-shaped cross section, and is overlapped and arranged at the corner of the shelf 3 and the sash vertical wall 9 connected to the shelf 3. At a certain point, the bottom wall 5 edge of the first and second retainers 4A and 4B, the rising wall 6
The holders 7 and 8 are bent and formed at the edges, and a sealing material 10 is applied to a parting portion between the holder 8 and the sash vertical wall 9 of the rising wall 6.
Doors are attached to the jaws 8a of the first and second retainers 4A and 4B.
The engaging groove 11a of the ether strip 11 is engaged,
The retainer 4A, 4B is
The basic configuration such as the fact that the base portions 12 are fitted respectively is the same as the above-described conventional one.

At the end of the holder 8 on the side of the rising wall 6 of the first retainer 4A disposed on the shelf 3 of the upper side 2B of the sash, the sealing material holding width is formed on the bent base of the holder 8. A notch 13 is formed over an appropriate length b from the terminal end of the holder 8 except for a.

In this embodiment, the jaw 8a of the holder 8 is used.
In addition, since a notch R is provided on the molding, the notch width of the notch portion 13 is set to this R stop position so that a tool to be described later is not caught.

If the length b of the notch 13 is too long, the function of holding the base 12 of the door weather strip 11 is impaired, and the end of the base 12 rises up from the notch 13 to improve the sealing property. For example, even when a flat brush used for applying the sealing material 10 is also used as a sealing material scraping tool, a length of 3 to 40 m / m is sufficient. is there.

According to the structure of the above-described embodiment, the sealing material 10 is connected to the holder 8 on the side of the rising wall 6 and the sash vertical when the first and second retainers 4A and 4B are joined on the shelf 3. It is applied to the parting portion with the wall 9 by using a flat brush or the like so as not to excessively apply the coating amount, but especially in the upper side 2B of the sash, as described above, the first retainer is used. 4A is disposed substantially horizontally and forms a toe on the shelf 3, so that the sealing material 10 applied to the parting portion between the holder portion 8 of the rising wall 6 and the sash vertical wall 9 is attached to the holder portion. No. 8 tends to hang down from the terminal end in a protruding manner.

On the other hand, a notch 13 is formed at the end of the holder 8 while leaving a sealing material holding width a at the bent base.
Is formed, the flow of the sealing material 10 in the width direction of the holder portion is suppressed within the range of the holding width a, and the notch portion 1 is formed.
There is no sagging from the three edges, and therefore, the phenomenon of sagging of the sealing material 10 from the toe of the holder portion 8 occurs. Holder part 8
The flat pen can be used to easily and neatly wipe the protruding sealing material hanging down with the flat brush.

As a result, the sealing material hanging down from the toe of the holder portion 8 is solidified in a raised state, and a gap is formed between the toe portion of the holder portion 8 and the base portion 12 of the door weather strip 11. Therefore, the door weather strip 11 can be properly assembled to the first retainer 4A, and the sealing performance can be maintained well.

[0019]

As described above, according to the present invention, the end of the holder on the rising wall side of the first retainer disposed on the shelf on the upper side of the sash has the sealing material holding width at its bent base. Since the cutout portion is formed with an appropriate length from the stop terminal, while avoiding the sealing material applied to the parting portion of the holder portion and the sash vertical wall from hanging down to the cutout portion, By facilitating insertion of a sealing material scraping tool into the holder portion from the cutout portion, the sealing material that hangs from the toe of the holder portion in a protruding manner with the tool is smoothly and cleanly wiped off. Can be.

Accordingly, it is possible to reliably prevent the sealing material hanging from the toe of the holder portion from solidifying in a protruding state and forming a gap with the door weather strip.
It has the effect of improving the sealability and further enhancing the quality and reliability.
