A door weather strip attached along a periphery of a rear door panel of a motor vehicle has a strip-shaped tubular main portion and a molded rear end portion connected to a rear end of the strip-shaped tubular main portion. The molded rear end portion is attached over a rear upper end portion of a door inner panel so as to cover a child lock lever hole formed in the rear upper end portion, and has an opening at the position corresponding to the child lock lever hole thereby enabling a child lock lever to slidably project therefrom.
