Glass run channel and glass run channel assembly

A glass run channel made of an elastic polymer material, the glass run channel being configured to be attached along a window frame of a door panel of a vehicle and formed to be long to guide movement of a window pane, the glass run channel comprising:

• a main body portion having a U-shaped cross-section, the main body portion comprising an inner sidewall portion configured to be disposed on a vehicle interior side, an outer sidewall portion configured to be disposed on a vehicle exterior side, and a bottom wall portion integrally connecting the inner sidewall portion and the outer sidewall portion;
• an inner lip portion which is configured to be disposed on the vehicle interior side and elastically deformable, the inner lip portion protruding from an end of the inner side wall portion toward an inside of the main body portion;
• an outer lip portion which is configured to be disposed on the vehicle exterior side and elastically deformable, the outer lip portion protruding from an end of the outer sidewall portion toward the inside of the main body portion;
• and
• an inner visible portion which is configured to be disposed on the vehicle interior side and which is elastically deformable, the inner visible portion protruding from the end of the inner sidewall portion toward an outside of the main body portion;
• and
• an outer visible portion which is configured to be disposed on the vehicle exterior side and which is elastically deformable, the outer visible portion protruding from the end of the outer sidewall portion toward the outside of the main body portion,
• wherein a lip portion which is one or each of the inner lip portion and the outer lip portion is formed such that:
• a bending point is located on a root side of the lip portion, the bending point at which the lip portion is bent when the lip portion is elastically deformed by sliding with the window pane at a time of moving up or down the window pane;
• a first covering portion having a friction coefficient smaller than that of the lip portion is formed on a distal end side of the lip portion with respect to the bending point within a part of a surface of the lip portion, the part of the surface of the lip portion being configured to contact the window pane while the lip portion slides with the window pane;
• and
• a second covering portion having a friction coefficient smaller than that of the lip portion is formed over a surface of the visible portion from the bending point of the lip portion or a position of the lip portion on the distal end side with respect to the bending point, and
• wherein the first covering portion is formed to be harder than the second covering portion.
