In the case of Patent Literature 1, the upper reinforcement provided with the sash guide mounting portion may be deformed when a load is applied. In order to prevent this, it is necessary to increase the thickness of the upper reinforcement, but the weight is greatly increased.

  On the other hand, according to Patent Document 2, since the load acting on the sash guide mounting portion is supported not only by the inner member of the rear pillar but also by the outer member, the load can be distributed to other parts of the vehicle by the outer member. Is possible. However, in view of the shape of the outer member extending downward from the sash guide mounting portion, it cannot be said that the load applied to the sash guide mounting portion is efficiently distributed to other parts.

  In view of such problems, the present invention provides a vehicle quarter part structure capable of efficiently transmitting and distributing a load acting on a sash guide mounting part of a vehicle quarter part at the rear side of the vehicle to other parts of the vehicle. The purpose is to do.

  In order to solve the above-mentioned problems, the present invention provides a sash that is a quarter inner panel disposed between a side door opening and a back door opening in a vehicle quarter part structure at the rear side of the vehicle, to which a sash guide is attached. A quarter inner panel that has a guide mounting part at the center lower part and a quarter inner front reinforcement that reinforces the rear edge of the side door opening. A quarter inner front reinforcement having an inclined portion extending forwardly of the vehicle while descending along the vehicle, and the quarter inner front reinforcement further includes an extension portion whose upper end extends to the rear of the vehicle, and the extension portion is a quarter inner portion. It must overlap with the panel sash guide mounting part. And features.

  According to the above configuration of the present invention, the sash guide mounting portion to which the load from the seat belt directly acts has a two-layer structure in which not only the quarter inner panel but also the quarter inner front reinforcement is added. As a result, the sash guide mounting portion is strongly reinforced. Further, the inclined portion of the quarter inner front reinforcement can efficiently transmit and distribute the forward and downward load mainly acting on the sash guide mounting portion to the rear wheel house under the vehicle.

  The lower edge of the extension may have an inclined shape that extends forward while descending. This is because the load acting on the sash guide mounting portion can be easily transmitted forward and downward by such a shape.

  A first bead bulging outward from the upper part of the quarter inner panel to the vicinity of the rear wheel house may be provided so as to pass between the rear edge of the side door opening and the sash guide mounting part. .

  This is because the rigidity of the vicinity of the rear edge of the side door opening is improved by the first bead, and the load acting on the sash guide mounting portion can be transmitted not only forward and downward, but also upward.

  Of the first bead, the rear wall of the first part in front of the extension part may swell deeper outside the rear wall of the second part below the first part. The first portion is closest to the extension portion that directly receives the load from the sash guide mounting portion in the first bead. This is because by providing a deep rear wall in the first portion, a large load can be received more reliably and then transmitted to the periphery.

  Of the first portion of the first bead, a second bead bulging inward from the rear wall to the front wall may be provided at a position in front of the sash guide mounting portion. That is, it is preferable to provide the second bead at the above-mentioned portion closest to the sash guide mounting portion in the first portion of the first bead. This is because the load is transmitted to the front end (the rear edge of the side door opening) of the quarter inner front reinforcement, and the load is transmitted not only downward but also upward including the side body outer panel.
