  The screw 7 a passes through the second bottom surface portion 75, and the retainer 7 is attached to the opening peripheral surface 5.

  The weather strip 8 is an elastic member, and seals 81 for sealing between the opening peripheral surface 5 and the door glass 4b, the opening flange 5a of the opening peripheral surface 5, and the end of the roof trim 9 of the vehicle compartment ceiling. And a cover portion 82 that covers a gap between the retainer 7 and the retainer 7.

  The seal portion 81 includes a lip-shaped first seal portion 81a and a hollow-shaped second seal portion 81b. The first seal portion 81a is formed so as to extend from the vehicle interior toward the vehicle exterior upward direction, and abuts against the vehicle interior side surface of the door glass 4b to seal. The second seal portion 81b is formed above the first seal portion 81a and abuts against the upper end portion of the door glass 4b to seal. Therefore, the seal portion 81 is configured to improve the sealing performance by sealing the space between the opening peripheral edge surface 5 and the door glass 4b independently at the vehicle interior side surface portion and the upper end portion of the door glass 4b. It has become.

  The cover portion 82 is formed to extend upward in the vehicle and is formed in a clip shape with a cover portion lip 82a that contacts the roof trim 9, and holds the opening flange 5a by sandwiching the opening flange 5a from below. The flange holding portion 82b is reinforced by a core member 82c.

  As shown in FIG. 3, the locking portion 83 is formed on the vehicle exterior side of the second seal portion 81 b, and a claw portion 83 a that is locked to the first holding portion 72 of the retainer 7, and the second holding portion of the retainer 7. And a protruding portion 83 b that is locked to 74. The claw portion 83a is formed to project obliquely downward from the vehicle outer side of the second seal portion 81b to the outer side. The protruding portion 83b is located above the claw portion 83a and is formed to protrude in a direction substantially opposite to the protruding direction of the claw portion 83a. The projection 83b extends slightly outward from the rotation locus (arrow A) of the projection 83b when the weather strip 8 is rotated with the flange holding portion 82b as the rotation center. Further, the protrusion dimension b of the protrusion 83b is formed larger than the protrusion dimension a of the claw part 83a.

  The operation of assembling the weather strip 8 to the vehicle body opening 3 in the vehicle 1 having the vehicle door glass seal structure configured as described above will be described. The assembling work of the weather strip 8 is a procedure in which the retainer 7 is first attached to the opening peripheral surface 5 and then the weather strip 8 is assembled to the opening flange 5 a and the retainer 7.

  First, the operator attaches the retainer 7 to the opening peripheral surface 5 of the vehicle body opening 3 using the screw 7a. Thereby, the retainer 7 is in a state in which the rib 7b and the abutting portion 76 abut against the opening peripheral surface 5 and the space between the retainer 7 and the opening peripheral surface 5 is sealed by the retainer mounting surface lip 7c. .

  Next, the work of holding the weather strip 8 at the end of the peripheral edge surface 5 of the opening is performed. Specifically, the operator pushes the cover portion 82 from below the opening flange 5 a and sandwiches the opening flange 5 a by the flange holding portion 82 b of the cover portion 82. As a result, the gap between the opening flange 5a and the roof trim 9 of the passenger compartment ceiling is covered by the cover portion 82, and the vehicle inner side of the weather strip 8 is held by the opening flange 5a and the vehicle outer side hangs down.

  Finally, the operation of locking the locking portion 83 of the weather strip 8 to the retainer 7 is performed. Specifically, the weather strip 8 is rotated upward with the flange holding portion 82b holding the opening flange 5a as the rotation center, and the outside of the weather strip 8 is brought into contact with the retainer 7. When the vicinity of the second seal portion 81b is pressed upward from this state, the claw portion 83a and the protruding portion 83b are pushed in while being deformed above the first holding portion 72 and the second holding portion 74, respectively, and the first holding portion is held. Locked to the portion 72 and the second holding portion 74.

  And it confirms that the latching | locking part 83 is latched by the retainer 7, and the assembly | attachment operation | work to the vehicle body opening part 3 of the weather strip 8 is complete | finished. At this time, since the protruding portion 83b is formed to protrude slightly outward from the rotation path of the protruding portion 83b, the protruding portion 83b is pushed above the second holding portion 74 with almost no resistance. Can do. Therefore, it is only necessary to confirm that the claw portion 83 a is pushed into the first holding portion 72 and is locked to the first holding portion 72.

  By such an assembling operation, the weather strip 8 has the flange holding portion 82b held by the opening flange 5a on the vehicle inner side and the locking portion 83 locked by the retainer 7 on the vehicle outer side. Can be firmly assembled.

  As described above, according to the vehicle door glass seal structure of the present embodiment, the claw portion 83a of the locking portion 83 is the second lower end portion on the vehicle exterior side of the weather strip 8, which is a position visible from the outside. It is formed in the vicinity of the vehicle exterior lower end portion of the seal portion 81b. Therefore, when performing the work of assembling the weather strip 8 to the opening peripheral surface 5, the operator can visually confirm whether or not the claw portion 83a is locked to the second seal portion 81b. Therefore, the claw portion 83a is surely locked to the second seal portion 81b, and the assembly failure of the weather strip 8 can be easily prevented.

  Further, the projection 83b of the locking portion 83 is formed so as to protrude outward from the locus of the projection 83b when the weather strip 8 is assembled to the retainer 7, so that the weather strip 8 is rotated to engage. When the stopper 83 is locked to the retainer 7, the protrusion 83 b can move up to the second holding part 74 without contacting the second holding part 74. Therefore, when the weather strip 8 is assembled, the operator can easily push the protruding portion 83b up above the second holding portion 74, and workability can be improved.

  Further, the claw portion 83a protrudes toward the vehicle exterior lower side of the first holding portion 72, and the lower side of the claw portion 83a abuts on and is locked to the first holding portion 72. Thereby, even if a downward force is applied to the weather strip 8 such as the weight of the weather strip 8, the weather strip 8 is prevented from falling off because the claw portion 83 a is locked to the first holding portion 72. be able to.

  On the other hand, the protruding portion 83 b protrudes upward from the second holding portion 74, and the side wall on the vehicle inner side of the protruding portion 83 b comes into contact with and is locked to the second holding portion 74. And the dimension b which this protrusion part 83b protrudes toward the upper direction of the 2nd holding | maintenance part 74 is formed larger than the dimension a which the nail | claw part 83a protrudes toward the vehicle outer side downward direction of the 1st holding | maintenance part 72. Yes. For example, when the door glass 4b is lowered or the door 4 is opened in a state where the door glass 4b and the seal portion 81 are adhered due to freezing or the like, the inside of the weather strip 8 is directed downward with the claw portion 83a as the rotation center. However, the weather strip 8 can be prevented from falling because the protruding portion 83b that protrudes larger than the claw portion 83a is locked to the second holding portion 74.

  In addition, a rib 7b that is in contact with the opening peripheral surface 5 is provided on the vehicle inner side of the retainer mounting surface lip 7c, which is a surface facing the opening peripheral surface 5 of the first bottom surface portion 73 of the retainer 7. . Thereby, since the space | interval of the part in which the retainer mounting surface lip 7c of the retainer 7 was provided, and the opening peripheral surface 5 is kept constant, it is because the retainer mounting surface lip 7c strongly press-bonds to the opening peripheral surface 5. It is possible to prevent deterioration in appearance and sealing performance due to gap generation.

  Further, the weather strip 8 has a seal part 81 and a cover part 82 formed integrally. As a result, it is possible to reduce the production cost and reduce the weight as compared with the case where the seal part 81 and the cover part 82 are separate parts, and the assembly work to the peripheral edge surface 5 can be performed at a time. Therefore, work efficiency can be improved.

  In the above-described embodiment, the weather strip 8 is rotated upward with the flange holding portion 82b as the center of rotation, and the locking portion 83 is locked to the retainer 7. The weather strip 8 may be rotated about the rotation center, and the other part may be used as a support shaft when the locking portion 83 is locked to the retainer 7. In any case, the projecting portion 83b is formed so as to project outward from the locus of the projecting portion 83b when the weather strip 8 is assembled to the retainer 7.
