A glass run includes a forked outer lip, wherein: one interval between a base root and an intermediate part of the inner lip is swelled and curved toward an inner-cabin side wall side and another interval between the intermediate part and a top end is swelled and curved toward an outer-cabin side wall side; a displacement point is on the connecting wall side compared with a top end of the outer-attaching lip of the outer lip; and the door glass abuts the inner lip and slidably moves toward the top end side and an outer-cabin side surface of the door glass abuts the outer-attaching lip and the inner-attaching lip while an inner-cabin side surface of the door glass abuts the inner lip.
