  In the case of the slide door main body 112 made of a press door, the groove depth of the mounting groove 133 inside the vehicle for the convenience of joining the flange portion 124 of the door inner panel 123 and the side plate portion 131 inside the vehicle of the channel member 129 by spot welding or the like. The length 133D must be larger than the groove depth 133d on the vehicle outer side of the mounting groove 133. Further, the groove width 133W of the mounting groove 133 must be increased for the purpose of joining the flange portion 127 of the door outer panel 126 and the side plate portion 132 on the vehicle exterior side of the channel member 129 by hemming. Further, in order to achieve flash surface formation, the door glass 114 is disposed close to the vehicle outside in the guide groove 147 of the glass run 137. For this reason, the length of the seal lip 140 on the vehicle inner side (the length from the base end portion to the tip end portion) is longer than the length of the seal lip 142 on the vehicle outer side. For this reason, the seal lip 140 inside the vehicle can be excessively elastically deformed toward the side wall 145 inside the vehicle of the glass run 137. As used herein, “excessive elastic deformation of the seal lip inside the vehicle” refers to elastic deformation exceeding the normal elastic deformation state of the seal lip inside the vehicle when the door glass is closed.

  Then, during the closing operation of the door glass 114 by the power window device, a rod-like foreign material 160 having a diameter of, for example, about 5 to 10 mm is sandwiched between the upper side portion of the window frame portion 116 of the slide door main body 112 and the door glass 114. In the case (refer to the two-dot chain line 160 in FIG. 6), if the foreign matter 160 has rigidity, there is no problem because the closing operation of the door glass 114 is stopped or opened by the operation of the jam protection function. . However, in the case of the foreign matter 160 having flexibility, it is expected that the foreign matter 160 will be forcibly sandwiched in the guide groove 147 in a folded manner without the jam protection function being operated (the solid line 160 in FIG. 6). reference). Accordingly, the seal lip 140 inside the vehicle is elastically deformed by the foreign matter 160 so as to overlap the side wall portion 145 inside the vehicle. Further, when the upper end portion of the door glass 114 rises beyond the side wall portion on the vehicle outer side (side plate portion 132 on the vehicle outer side) of the guide groove 147, the jam protection function is determined to be in the dead zone region 162R and does not operate. Accordingly, it is impossible to prevent the foreign material from being folded in two.

  The problem to be solved by the present invention is to provide a sliding door for an automobile that can prevent a foreign object from being sandwiched between the upper side portion of the window frame portion of the sliding door body and the door glass. .

Towards A seal lip on the outside of the vehicle that is formed in an inclined shape and elastically contacts the door glass, and the side wall on the inside of the vehicle is subjected to excessive elastic deformation of the seal lip on the inside of the vehicle when the door glass is closed. A deformation restricting portion for restricting by contact is provided. According to this configuration, when the door glass is closed, when the foreign material having flexibility sandwiched between the upper side of the window frame portion of the slide door body and the door glass is about to be sandwiched in the guide groove, the glass A seal lip on the inner side of the run comes into contact with the deformation restricting portion. Thereby, excessive elastic deformation of the seal lip inside the vehicle can be restricted. Therefore, it is possible to prevent the foreign material from being folded in between the upper side portion of the window frame portion of the slide door body and the door glass. In addition, in a sliding door for an automobile equipped with a power window device having a jam protection function, the jam protection function can be operated before the door glass enters the dead zone, thereby preventing foreign objects from being caught in a double-folded manner. be able to.

  In a second aspect based on the first aspect, the deformation restricting portion of the glass run is formed in a cross-sectional sideways mountain shape having a top corresponding to the middle portion of the seal lip on the vehicle interior side. According to this configuration, when the seal lip inside the vehicle is excessively elastically deformed, excessive elastic deformation of the seal lip inside the vehicle is regulated early by the middle part of the seal lip coming into contact with the top of the deformation regulating portion. be able to.

In the sliding door 10 for automobiles, as shown in FIG. 4, when the door glass 14 is closed by the power window device, between the upper side portion 17 of the window frame portion 16 of the sliding door main body 12 and the door glass 14, for example, Conventionally, when a foreign material 60 having a rod-like flexibility having a diameter of about 5 to 10 mm is sandwiched between the guide grooves 47, the seal lip 40 on the inner side of the glass run 37 is excessively elastically deformed. .
However, according to the present embodiment, the middle part 41 of the seal lip 40 on the vehicle inner side abuts on the top 57a of the built-up portion 57 of the side wall 45 on the vehicle inner side. Thereby, excessive elastic deformation of the seal lip 40 inside the vehicle can be regulated. Therefore, it is possible to prevent the foreign matter 60 from being sandwiched between the upper side portion 17 of the window frame portion 16 of the slide door main body 12 and the door glass 14. Further, in the automobile sliding door 10 including the power window device having the jam protection function, the jam protection function can be operated before the door glass 14 enters the dead zone 62R (see FIG. 4).

  Further, the build-up portion 57 of the glass run 37 is formed in a cross-sectional sideways mountain shape having a top portion 57a corresponding to the middle portion 41 of the seal lip 40 inside the vehicle. Therefore, at the time of excessive elastic deformation of the seal lip 40 inside the vehicle, the middle part 41 of the seal lip 40 comes into contact with the top 57a of the built-up portion 57, so that excessive elastic deformation of the seal lip 40 inside the vehicle is accelerated. Can be regulated.

  Further, the position of the top portion 57a of the built-up portion 57 of the glass run 37 (see the dimension difference L in FIG. 3) is within a range of 2.5 to 5 mm below the lowermost end A on the side wall portion 46 side on the outside of the vehicle. Is set. Therefore, in the case where the thickness of the foreign matter 60, for example, the diameter is in the range of 5 to 10 mm, excessive elastic deformation of the seal lip 40 inside the vehicle can be effectively restricted. That is, when an experiment was performed by changing the dimensional difference L based on an existing glass run, when the dimensional difference L is less than 2.5 mm or more than 5 mm, excessive elastic deformation of the seal lip 40 on the inside of the vehicle is restricted. It turned out that the effect to do declines. Accordingly, the position of the top portion 57a of the built-up portion 57 of the glass run 37 is set within a range of 2.5 to 5 mm below the lowermost end A on the side wall portion 46 side on the outside of the vehicle, whereby the seal on the inside of the vehicle is set. Excessive elastic deformation of the lip 40 can be effectively controlled.

  In particular, when the diameter of the foreign material 60 is 5 mm, the most effective is obtained when the dimensional difference L is 2.5 mm. In addition, when the diameter of the foreign material 60 is 10 mm, it is most effective when the dimensional difference L is 5 mm. That is, the effect of restricting excessive elastic deformation of the seal lip 40 inside the vehicle is the highest. Therefore, a power window device having the best effect for preventing the foreign object 60 from being sandwiched between the upper side portion 17 of the window frame portion 16 of the slide door body 12 and the door glass 14 and having a jam protection function is provided. The best effect is obtained with respect to the operation of the jam protection function in the automobile sliding door 10 provided.
