Abstract
A glass run channel assembly is provided. In the glass run channel assembly, after being mounted, an elastic force is generated in a vertical side portion which contacts a vertical frame of a door frame, and an elastic force is generated in an upper side portion which contacts an upper frame of the door frame. Here, the cross-sectional shapes of the upper side portion and the vertical side portion are adjusted such that the frictional force per unit length obtained by multiplying a coefficient of static friction of the upper side portion with the upper frame by the elastic force is larger than a frictional force per unit length obtained by multiplying the coefficient of static friction of the vertical side portion with the vertical frame by the elastic force.
