By being drawn, the sealing performance between the front side door 10 and the side member 18 can be enhanced. Further, since the magnetic force acts at the moment when the front side door 10 is completely closed, the closing speed of the front side door 10 can be reduced, and the door closing property is improved.

  Further, while the front side door 10 is closed, the outer wall 18C of the side member 18 and the weather strip 16 are attracted by the magnetic force between the outer wall 18C of the side member 18 and the magnetic body 30 to seal the seal. Since the property is enhanced, the reaction force can be weakened compared to a general weather strip (one having no magnetic material). By reducing the reaction force of the weather strip 16, the door closing speed can be further reduced.

  On the other hand, as shown in FIG. 5, in the front side door 100 according to the comparative example, a magnetic body 106 is provided at a position facing the side member 18 of the outer peripheral portion 104 of the weather strip 102. No inner member is provided inside the outer peripheral portion 104. In this configuration, when the front side door 100 is opened, the magnetic body 106 is exposed on the outer peripheral portion 104 of the weather strip 102, so that a substance having a magnetic force contained in the air is attracted to the periphery of the weather strip 102. There is a possibility of accumulating.

  On the other hand, in the weather strip 16 of the present embodiment, the magnetic body 30 provided on the inner member 28 does not contact the outer peripheral portion 24, so that the magnetic force of the magnetic body 30 acts on the outside of the outer peripheral portion 24 of the weather strip 16. Therefore, it is possible to prevent or suppress the attraction of a substance having a magnetic force contained in the air.
