PROBLEM TO BE SOLVED: To provide a vehicular weather strip and a manufacturing method thereof, installed in an upper edge part of an opening part of a vehicle body, and improving water cutoff performance and sound insulation performance of a vehicle.SOLUTION: A first or third seal lip part 28A or 28C and a fitting base body part 27 are molded, for example, by flexible foam EPDM solid rubber, and are molded in specific gravity Sg of 0.5 or 0.8. The first seal lip part 28A is formed on the upper end of a vertical wall 29A and is also extended in the length direction, and a central thickness t1 is set thicker than a thickness t2 of an outer wall surface of its base point 28a, and a groove 28b having a cross-sectional shape of a U shape or a circular arc shape is formed in the length direction on the outer wall surface, and when closing a front door 22, the bending action is facilitated. 30 and 31 are a small projection formed of high foam EPDM sponge rubber being, for example, 0.1 or 0.3 in specific gravity Sg, and a cross-sectional shape is formed in an angle shape by having the high seal function as a seal lip part by extending in the length direction.SELECTED DRAWING: Figure 2 |
