A cover member for automobiles for partially covering up a panel adjacent to an article that opens and closes like a door or a body, the cover member comprising: a cover body extending lengthwise, of which top end side is mounted in such a manner as to extend substantially in parallel with said panel and the top end has an anchoring part formed thereon which is separate from the panel; a protective member having a substantially U-shape in cross-section which fastens the top end of said cover body, the substantially U-shape including: a first side wall having a hook part formed thereon for covering up the anchoring part of said cover body thereby fitting with the anchoring part; a second side wall which makes elastic contact with a surface side on an inner side compared with the top end of the cover body; and a connecting wall connecting the first side wall and the second side wall; characterized in that: said anchoring part of said cover body protrudes toward an inner-cabin side, which is the panel side, from the top end of said cover body; said second side wall of said protective member is positioned on an outer-cabin side, which is an opposite side to said panel side, as compared with the first side wall and makes elastic contact with a surface on an outer-cabin side of said cover body; and a projection, which is substantially perpendicular to a direction in which said first side wall extends and which protrudes toward an inner-cabin side, is formed on an outer side of the first side wall for the first side wall to expand with respect to the second side wall when the protective member is bent so that the connecting wall of said protective member warps toward an opposite side to a side in which the first side wall and the second side wall extend. a cover body extending lengthwise, of which top end side is mounted in such a manner as to extend substantially in parallel with said panel and the top end has an anchoring part formed thereon which is separate from the panel; a protective member having a substantially U-shape in cross-section which fastens the top end of said cover body, the substantially U-shape including: a first side wall having a hook part formed thereon for covering up the anchoring part of said cover body thereby fitting with the anchoring part; a second side wall which makes elastic contact with a surface side on an inner side compared with the top end of the cover body; and a connecting wall connecting the first side wall and the second side wall; characterized in that: said anchoring part of said cover body protrudes toward an inner-cabin side, which is the panel side, from the top end of said cover body; said second side wall of said protective member is positioned on an outer-cabin side, which is an opposite side to said panel side, as compared with the first side wall and makes elastic contact with a surface on an outer-cabin side of said cover body; and a projection, which is substantially perpendicular to a direction in which said first side wall extends and which protrudes toward an inner-cabin side, is formed on an outer side of the first side wall for the first side wall to expand with respect to the second side wall when the protective member is bent so that the connecting wall of said protective member warps toward an opposite side to a side in which the first side wall and the second side wall extend. said anchoring part of said cover body protrudes toward an inner-cabin side, which is the panel side, from the top end of said cover body; said second side wall of said protective member is positioned on an outer-cabin side, which is an opposite side to said panel side, as compared with the first side wall and makes elastic contact with a surface on an outer-cabin side of said cover body; and a projection, which is substantially perpendicular to a direction in which said first side wall extends and which protrudes toward an inner-cabin side, is formed on an outer side of the first side wall for the first side wall to expand with respect to the second side wall when the protective member is bent so that the connecting wall of said protective member warps toward an opposite side to a side in which the first side wall and the second side wall extend.
