<P>PROBLEM TO BE SOLVED: To provide a glass run which surely suppresses generation of an abnormal noise even in long-term use. <P>SOLUTION: The glass run 1 includes a body 11 and outdoor side and indoor side seal lips 12, 13. The body 11, which includes a base 14 and outdoor sidewall 15 and indoor sidewall 16 extending from the base 14, forms an approximately U-shape in cross section as a whole. Sliding parts 31, 32 made of hard TPO are provided on the surface at door glass DG side of both seal lips 12, 13. Of both seal lips 12, 13, the portions where at least the sliding parts 31, 32 are provided constitute vibration control parts 12a, 13a made of a vibration-damping material. These vibration control parts 12a, 13a are formed with the TPO and have compatibility with TPV constituting the body 11 etc. in respect of a fact that both are olefin-base materials. The loss factor tanδ of the TPO is 0.5 or more at 20°C. <P>COPYRIGHT: (C)2010,JPO&INPIT |
