SEAL STRUCTURE OF VEHICULAR DOOR FRAME

PROBLEM TO BE SOLVED: To provide a seal structure of a vehicular door frame capable of further improving the sealability of a coupled portion between a door frame forming an upper opening portion of a vehicular door and a division frame dividing the upper opening portion into two portions, without increasing the number of part items or manufacturing manhours. SOLUTION: In the seal structure, a seal member 30 is integrally provided with: an upper seal portion 31 which is more upward than a glass guide rail 6 and comes into fluid-tight contact with a lower surface of a coupling door frame 13; a lower seal portion 32 which extends downward from the upper seal portion 31 and comes into fluid-tight contact with an upper end of a coupling frame 18; an outer seal portion 33 coming into fluid-tight contact with an internal surface of an outer door frame 11 and an external surface of the outer frame 16 over a portion between the upper seal portion 31 and the lower seal portion 32; and an inner seal portion 34 coming into fluid-tight contact with an internal surface of an inner door frame 12 and an external surface of an inner frame 17 over a portion between the upper seal portion 31 and the lower seal portion 32.
