Door for vehicle

A door (30) for a vehicle (10) is provided which includes a run channel (44) and a door glass (45) slidable up and down along the run channel. A rear edge (63) of the door glass in sliding contact with a rear channel (59) of the run channel has respective projecting portions (65,66) at upper and lower end portions thereof. The projecting portions project more than a middle portion of the rear edge positioned centrally in an up-and-down direction of the rear edge. The rear edge is deeply received in a groove formed in the rear channel not throughout the length thereof but at the projecting portions so as to reduce a slide resistance which the door glass undergoes when sliding relative to the run channel. The upper edge (62) of the door glass is formed such that, when the upper edge abuts on an upper channel (58) of the run channel, an upper front end (71) and an upper rear end (72) of the upper edge abut on the upper channel prior to an upper middle portion (73) of the upper edge.
