Claim:
A weather strip adapted to provide a seal between a closing member for closing an opening in a body of a motor vehicle and an opening portion of the body of the motor vehicle, comprising: a trim portion for attachment to a flange provided in one of the closing member and the opening portion; and a seal portion integrally formed with said trim portion for contacting one of the opening portion and the closing member to provide a seal between the closing member and the opening portion, wherein said trim portion includes an outer side wall, an inner side wall and a bottom wall, and has a generally U-shaped cross-section, wherein said trim portion includes a plurality of outer holding lips in an interior surface of said outer side wall, and an inner holding lip in an interior surface of said inner side wall so as to project into an interior of said trim portion obliquely, wherein said inner holding lip includes a base part extending from said interior surface of said inner side wall, a main lip formed continuously with an end of said base part in an extending direction of said base part, and a sub-lip formed to project from a side surface of said end of said base part, which faces an opening of said trim portion, towards an opening of said trim portion obliquely with respect to said main lip, wherein said sub-lip is made shorter than said main lip, and an end of said sub-lip is located on an opening side of an interior surface of a joint between said base part and said inner side wall, wherein the sub-lip is formed such that a thickness thereof gradually decreases from a root thereof toward an end thereof, and such that an entire length thereof is greater than the thickness of the root, which is continuous with the base part, wherein the inner holding lip includes a slit that extends from an exterior surface of the joint between the base part and the inner side wall inwardly of the joint, and wherein a projection is provided in one of a surface of the inner side wall and a surface of the base part, which define the slit, in a vicinity of an entrance of the slit.
