PURPOSE: To increase the universality of a door sash as well as to aim at a reduction in the cost of production, by embracing the base of a subweather strip at a holding part.

CONSTITUTION: A channel-like holding part 2c1 is made up on the topside of a baggy rigid part 2c of a door sash 2 along the longitudinal direction of the door sash 2, and using this holding part 2c1, a jetty part 8a being formed on the base of a subweather strip 8 is embraced whereby the subweather strip 8 is attached to the baggy rigid part 2c. As it is constituted of suchlike, the subweather strip 8 can be set up with certainty without installing a setting hole for clip use in the baggy rigid part 2c of the door sash 2 yet using a both-sided adhesive tape.
