It is assembled in the invaded state.

  The glass run mold forming part assembly structure of the embodiment is configured as described above, and the glass run mold forming part 1 is oriented substantially parallel to the horizontal side part 204 and the vertical side part 205 of the window frame frame 201. In this state, the glass run mold forming part 1 can be assembled by a simple operation of inserting the glass run mold forming part 1 between the horizontal side part 204 and the vertical side part 205 of the window frame frame 201. Therefore, one locking piece of the conventional pair of positioning blocks 105 and 106 shown in FIG. 14, for example, the positioning block 105 is brought into contact with the positioning block receiving surface 202a at one end of the channel member 202, so that the positioning block Assembling workability is higher than that in which the other positioning block 106 is brought into contact with the positioning block receiving surface 203a of one end of the other channel member 203 while the mold forming portion 104 is rotated around 105. improves.

In the conventional example shown in FIG. 13, as described above, the assembly dimension error (variation) of the channel members 202 and 203 between the positioning block receiving surfaces 202a and 203a of the channel members 202 and 203 and the positioning blocks 105 and 106 is different. ), For example, gaps δ ₁ and δ ₂ of about 3 mm are set. For this reason, rainwater may flow into the vehicle interior from the gaps δ ₁ and δ ₂ , and in order to prevent this, a sealing material such as an ept seal has to be used. However, in the present invention, the glass run mold forming part 1 can be positioned by the contact surface 21 of the positioning block 3 provided in the glass run mold forming part 1 and the engaging part 31 provided at one end of the watertight lip 4. . That is, positioning can be performed only at the end of the glass run mold forming part 1 on the vertical side 205 side. Therefore, it is not necessary to provide a gap as an absorption allowance for the dimensional error or the like between the end surface of the vertical side portion 205 and the contact surface 21 of the positioning block 3, and the end portion of the watertight lip 4 and By engaging the engaging portion 31 with the second fitting portion 208 and the first fitting portion 207, a lap allowance α can be secured with respect to the end surface 205a of the vertical side portion 205, and rainwater can surely enter. Can be prevented. Further, also at the end portion of the glass run mold forming portion 1 on the side portion 204 side, the end surface 204a of the side portion 204 contacts the lower end portion 32a of the inclined surface 32 of the watertight lip 4 and is continuous with the end surface 204a. Since the intrusion portion 33 provided in this manner is assembled in a state where the intrusion portion 33 has intruded into the lateral side portion 204, the intrusion of rainwater can be reliably prevented. From the above, it is possible to eliminate a sealing material such as an ept seal that has been conventionally required. In the above embodiment, the abutting surface 21 and the engaging portion 31 of the positioning block 3 are provided at the end portion on the vertical side portion 205 side of the glass run mold forming portion 1, and the end portion on the horizontal side portion 204 side is provided.
