Specifically, the depth D1 of the spot facing 53 is formed so as to become shallower as the distance from the general portion 41 in the changing portion 42 increases.

Hereinafter, the operation and effect of the first embodiment will be described.
As shown in FIGS. 2, 4, and 6, in the vehicle door 20, a door opening 14 provided in the vehicle body 11, a door main body 21 that covers the door opening 14 so as to be opened and closed, and a door main body 21. And a door seal 23 that contacts the edge 14a of the door opening 14.

  The door main body 21 has a constant distance E1 between the edge portion 21a of the door main body 21 and the edge portion 14a of the door opening portion 14 and a door connected to the general portion 41 and away from the general portion 41. And a change portion 42 in which the distance F1 between the edge portion 21a of the main body 21 and the edge portion 14a of the door opening 14 is increased.

  A seal base 51 that is continuously formed on the door seal 23 from the general portion 41 to the changing portion 42 and supported by the door body 21, and extends from the seal base 51 to the edge 14 a side of the door opening 14, 52a is provided with the outer lip part 52 which contact | abuts to the edge part 14a of the door opening part 14, and the counterbore part 53 provided between the outer lip part 52 and the seal base 51, and the vehicle outer side.

  A distance b1 from the spot facing portion 53 in the changing portion 42 to the tip 52a of the outer lip portion 52 is set to be longer than a distance a1 from the spot facing portion 53 in the general portion 41 to the tip 52a of the outer lip portion 52.

  A bending groove 71 for bending that is concave toward the outside of the vehicle is provided on the inner lip portion 52 side of the outer lip portion 52 in the changing portion 42, and when the extension line L <b> 1 is drawn in the forming direction of the bending groove 71, the outer lip portion 52. The distance c1 from the intersection P1 of the vehicle outer side surface 52b and the extension line L1 to the tip 52a of the outer lip portion 52 is substantially the same as the distance a1 from the spot facing portion 53 in the general portion 41 to the tip 52a of the outer lip portion 52. That is, since the bending base point of the outer lip portion 52 on the outer side surface 52b of the outer lip portion 52 can be made substantially the same in the general portion 41 and the changing portion 42, the appearance of the door seal 23 and the deterioration of the sealing performance are prevented. be able to.

  Further, in the general portion 41, the outer lip portion 52 can be stably bent with the counterbore portion 53 as a base point. Since the bending groove 71 is not provided in the general portion 41, the complexity of the structure of the door seal 23 can be avoided.

  As shown in FIGS. 6 and 11, in the vehicle door 20, the seal base 51 protrudes in the vicinity of the counterbore 53 and toward the back surface 21 b of the door body 21 and contacts the back surface 21 b of the door body 21. The contact portion 65 is in contact, and the projecting length H <b> 1 of the contact portion 65 is longer in the changing portion 42 than in the general portion 41. In other words, since the rigidity of the changing portion 42 in the vicinity of the counterbore portion 53 can be increased by the contact portion 65, the outer lip portion 52 can be prevented from being bent in the changing portion 42 with the counterbore portion 53 as a base point.

  Due to the reaction force of the contact portion 65, the door seal 23 receives a force on the side away from the back surface 21 b of the door body 21. Since the changing portion 42 is formed longer than the general portion 41 in the protruding length H1 of the abutting portion 65, the changing portion 42 can receive a larger amount of reaction. Accordingly, the outer lip portion 52 in the changing portion 42 can be bent with the counterbore portion 53 as a base point.

  In the vehicle door 20, the protruding length H <b> 1 of the contact portion 65 is formed so as to become longer as the change portion 42 moves away from the general portion 41. That is, as the distance F1 between the edge 21a of the door body 21 and the edge 14a of the door opening 14 becomes longer, the protrusion length H1 of the contact portion 65 is also set longer. It can suppress that the length of the contact part 65 becomes long.

  Moreover, since the change of the length of the contact part 65 from the general part 41 to the change part 42 can be moderated, the door main body 21 and the contact part 65 can be made to contact reliably. Note that if the length of the contact portion 65 is suddenly changed, a gap may be formed between the contact portion 65 and the door body 21.

  As shown in FIGS. 2, 6, and 11, in the vehicle door 20, the changing portion 42 is a portion provided from the general portion 41 toward the corner 39 of the door main body 21. An insert member 62 that reinforces the door seal 23 is provided at a corner attachment portion (door seal corner portion) 58 of the door main body 21 of the door seal 23, and the protruding length H1 of the contact portion 65 in the changing portion 42 is from the general portion 41 side. In the insert range G1 of the insert member 62, it was formed shorter as it went toward the corner 39. That is, since the rigidity is enhanced by the insert member 62 in the vicinity of the corner 39 where the distance F1 between the edge 21a of the door main body 21 and the edge 14a of the door opening 14 is greatly separated, the outer lip 52 is unexpectedly collapsed (seat It is possible to suppress the collapse) of the bore portion 53 as a base point.

  Further, since the protruding length H1 of the contact portion 65 is returned from the insert portion where the insert member 62 is provided, for example, when the extending direction of the door seal 23 changes with the corner 39 as a boundary, the general portion of the changed portion is changed. 41 can be continuously connected.

  As shown in FIG. 11, in the vehicle door 20, the depth D <b> 1 of the counterbore part 53 is formed to be shallower than the depth of the general part 41. That is, since the rigidity of the changing portion 42 in the vicinity of the counterbore portion 53 can be increased, the outer lip portion 52 can be prevented from being bent at the changing portion 42 with the counterbore portion 53 as a base point.

  Moreover, since the depth D1 itself of the spot facing part 53 becomes shallow, the rigidity of the outer lip part 52 is increased, and the overall fall of the outer lip part 52 can be suppressed.

  As shown in FIG. 11, in the vehicle door 20, the depth D <b> 1 of the counterbore part 53 is formed so as to become shallower as it moves away from the general part 41 in the changing part 42, so that it sits more than necessary. It can suppress that the depth D1 of the bore part 53 becomes shallow.

  As shown in FIGS. 2, 8, and 11, in the vehicle door 20, the door body 21 is provided with a garnish 32 that covers a part of the door seal 23 outside the vehicle. The door seal 23 is provided with a garnish contact portion 61 that contacts the garnish 32, and the insert member 62 is provided in a range where the garnish contact portion 61 is provided (insert range G1). That is, the gap between the garnish 32 and the door seal 23 can be closed by the garnish contact portion 61.
