Weatherstrip fixing structure
A portion of a peripheral wall of a hollow portion receiving a compression load when a door is closed has a slit-shaped core removal hole through which a core member used to mold the inner surface of the hollow portion is removed from the hollow portion. An attachment member has an insertion plate portion to be inserted into the core removal hole. The thickness of the insertion plate portion is set to be substantially equal to the width of an opening of the core removal hole.
1. A weatherstrip fixing structure for fixing, to a door of a vehicle or a vehicle body, a weatherstrip configured to seal a gap between the door and an edge of an opening of the vehicle body,
the weatherstrip including:
a weatherstrip intermediate molded part having a hollow portion made of an elastic material, the hollow portion being compressed by the door and the vehicle body to be elastically deformed when the door is closed; and
an attachment member configured to fix the weatherstrip intermediate molded part to the door or the vehicle body, and made of a material harder than the elastic material forming the hollow portion, wherein
a portion of a peripheral wall of the hollow portion receiving a compression load when the door is closed has a slit-shaped core removal hole through which a core member used to mold the inner surface of the hollow portion is removed from the hollow portion,
the attachment member has an insertion plate portion to be inserted into the core removal hole,
a thickness of the insertion plate portion is set to be substantially equal to a width of an opening of the core removal hole,
the peripheral wall of the hollow portion has a fastening hole,
the attachment member has a fastening portion to be inserted into, and fastened into, the fastening hole,
the weatherstrip is fixed to the door,
the peripheral wall of the hollow portion includes a fixing plate portion extending along a fixing surface of the door on which the weatherstrip is fixed, and a curved wall portion continuous with the fixing plate portion and curved away from the fixing plate portion to be in contact with the vehicle body,
the core removal hole opens between the fixing plate portion and the curved wall portion,
the attachment member includes a substrate portion arranged inside the hollow portion to extend along the fixing plate portion, and an engagement protrusion protruding from the substrate portion through the fixing plate portion toward an outside of the hollow portion,
the engagement protrusion is inserted into, and engaged with, an engagement hole of the door, and
the fastening hole is formed in the curved wall portion.
2. The weatherstrip fixing structure of claim 1 , wherein
the substrate portion of the attachment member extends along the fixing plate portion of the hollow portion, and
the substrate portion of the attachment member includes a fixing plate portion-side fastening portion protruding from the substrate portion so as to be fastened to the fixing plate portion.
3. The weatherstrip fixing structure of claim 2 , wherein
a portion of the substrate portion including the fixing plate portion-side fastening portion is more distant from the fixing surface of the door than a portion of the substrate portion including the engagement protrusion is.
4. The weatherstrip fixing structure of claim 1 , wherein
the insertion plate portion of the attachment member extends from the substrate portion of the attachment member inside the hollow portion, and
a thickness of the substrate portion is set to be larger than that of the insertion plate portion.
