PROBLEM TO BE SOLVED: To allow elastic deformation as elastically expending and supporting a main hollow section by making this main hollow section have a coil spring member coiled with a shape memory alloy spring member along the inner axial center direction of its hollow inner part. SOLUTION: This weather strip 20 is composed of making main hollow sections 7 and 13 have two coil spring members 8a and 14a coiled with a shape memory alloy spring member along the inner axial center direction of its hollow inner part. Therefore, the coil spring members 8a and 14a receive each pressure from a door sash, door panel, or a body panel almost equally to each longitudinal direction of the main hollow sections 7 and 13, and also over the whole area of its hollow inner circumferential surface, and thus they are deformable as elastically expanding and supporting the main hollow sections 7 and 13. |
