PROBLEM TO BE SOLVED: To maintain a friction factor below a specified value for a long time by adjusting the surface hardness of a urethane sliding layer within a specified range. SOLUTION: A weather strip for glass is made of ethylene propylene contained rubber, being constructed by mold-connecting molding parts 22 and 24 to extrusion parts 12, 14 and 16 and forming a urethane sliding layer in a glass slide-moving part. A urethane sliding layer in each of the molding parts 22 and 24 is formed in such a manner that base polymer uses polyester polyole of a molecule amount of 10 to 90 thousands, preferably 30 to 50 thousands as polyole component, hardening is allowed below 100 deg. and formed by a one-coat type paint containing primer and adjusted within the range of over pencil hardness B and lower than H, preferably near the range of HB. |
