  FIG. 2 is a horizontal sectional view of the side door glass frame fastening part structure 10, and FIG. 3 is a front view of the lock reinforcement. As shown in FIG. 2, the door glass frame 14 has a substantially U-shaped cross section, and a glass run 22 having a substantially U-shaped cross section is fitted inside the door glass frame 14. Lip portions 22A are provided at both ends of the glass run 22, respectively. The lip portion 22A is disposed in a gap generated between the glass run 22 and the door glass 12, and contacts the door glass 12 in a slidable state to seal between the door glass 12. The door glass 12 can be raised and lowered by a lifting device 24 (see FIG. 4) attached to the inner panel 16, and is guided by the door glass frame 14 through the glass run 22.

  As shown in FIG. 2, the bracket 18 can be fixed to the inner panel 16 by bolts 26 and nuts 28. The bracket 18 has a long plate shape, and is provided with a fastening portion 18 </ b> A that is fastened by being brought into surface contact with the fastening portion 16 </ b> A of the inner panel 16 at one end in the longitudinal direction (described later). In addition, a joint 18B that is joined (welded) to the door glass frame 14 is provided at the other end of the bracket 18 in the longitudinal direction.

  The angle formed by the fastening portion 18A and the connecting portion 18C of the bracket 18 forms an obtuse angle, and the angle formed by the connecting portion 18C, the joint portion 18B, and the connecting portion 18C forms an obtuse angle. For this reason, the angle formed by the fastening portion 18A and the joint portion 18B is also an obtuse angle.

  Here, when the closing operation of the side door 11 is performed in a state where the door glass 12 is opened, the inertia force F of the door glass 12 acts along the arrow direction. The translational load is input to the fastening portion 16A of the inner panel 16 and the fastening portion 32 of the fastening portion 18A of the bracket 18 via the bracket 18. As described above, since the angle formed by the fastening portion 18A and the joint portion 18B of the bracket 18 is an obtuse angle, the joint portion 18B is offset with respect to the center portion O (input point of translational load) of the fastening portion 32 ( L).

In this manner, by fastening the lock reinforcement 20 at the fastening portion 32 of the bracket 18 and the inner panel 16, the fastening portion 32 is increased in thickness due to the plate thickness of the lock reinforcement 20 at the fastening portion 32. Reinforced and the surface rigidity of the fastening portion 32 is improved.

  A flange portion 36 is formed in the fastening portion 20 </ b> A of the lock reinforcement 20. Thereby, the intensity | strength and rigidity of the said lock reinforcement 20 can be improved compared with the case where the lock reinforcement 20 is only plate shape. That is, the surface rigidity of the bracket 18 and the fastening portion 32 of the inner panel 16 can be further improved.

  Here, as shown in FIG. 3, the flange portion 36 is formed continuously from the vehicle lower portion 20 </ b> B to a position higher than the center portion O of the fastening portion 20 </ b> A, around the vehicle front side of the fastening portion 20 </ b> A. . As shown in FIG. 2, a load directed downward of the vehicle acts on the bracket 18 due to the weight of the door glass 12, so that the flange portion 36 is formed on at least the vehicle lower portion 20 </ b> B side of the lock reinforcement 20, thereby It can reinforce against the load which acts on.

  However, when the flange portion 36 is provided only on the vehicle lower portion 20B side of the lock reinforcement 20, stress due to the weight of the door glass 12 is concentrated on the vehicle lower portion 20B side. For this reason, as shown in FIG. 2, the stress is concentrated by the flange portion 36 being continuously formed at least from the vehicle lower portion 20B of the lock reinforcement 20 to a position higher than the center portion O of the fastening portion 20A.
