Abstract

An automobile weather strip includes an extrusion-molded portion and a die-molded portion. The die-molded portion includes: a mount base to be mounted on the periphery of the door; and a hollow seal integrally molded with the mount base and coming into elastic contact with the circumferential edge of a vehicle body opening. The mount base includes a bottom in the shape of a plate. The bottom has a core removal slit for removing a core, and the core removal slit extends in a longitudinal direction of the die-molded portion. The core removal slit has a length set shorter than the length of the core in the same direction. The bottom includes a thick-walled portion at a portion adjacent to an edge of the core removal slit. The thick-walled portion is thicker than the other portions of the bottom.

Claims (21)

1. An automobile weather strip to be attached to a periphery of a door of an automobile to seal a gap between a circumferential edge of a vehicle body opening and the periphery of the door, the automobile weather strip comprising:

an extrusion-molded portion formed by extrusion molding; and

a die-molded portion formed by molding die and connected to a longitudinal end of the extrusion-molded portion,

the extrusion-molded portion including:

a mount base configured to be attached on the periphery of the door; and

a hollow seal integrally molded with the mount base and coming into elastic contact with the circumferential edge of the vehicle body opening when the weather strip is attached to the periphery of the door,

the die-molded portion including:

a mount base configured to be attached to the periphery of the door; and

a hollow seal integrally molded with the mount base of the die-molded portion and coming into elastic contact with the circumferential edge of the vehicle body opening when the weather strip is attached to the periphery of the door,

the mount base of the die-molded portion including a bottom in a shape of a plate extending along the periphery of the door,

the bottom having a core removal slit for removing a core used to form an inner surface of the hollow seal, the core removal slit extending in a longitudinal direction of the die-molded portion,

the core removal slit having a length set shorter than a length of the core in a same direction,

the bottom having a non-uniform thickness and including a thick-walled portion at a portion adjacent to an edge of the core removal slit, the thick-walled portion being thicker than other portions of the bottom and protruding in an inward direction from a side of the bottom that contacts the periphery of the door to reinforce the edge of the core removal slit.

2. The automobile weather strip of claim 1 , wherein

the thick-walled portion includes an inclined surface with an increasing thickness toward the edge of the core removal slit.

3. The automobile weather strip of claim 1 , wherein

the bottom has a clip attachment hole between a connected portion where the bottom is connected to the extrusion-molded portion and the edge of the core removal slit, the clip attachment hole being a hole to which a clip configured to engage with the periphery of the door is attachable.

4. The automobile weather strip of claim 1 , wherein

the thick-walled portion protrudes toward an opposite side from a contact side of the bottom with the periphery of the door.

5. The automobile weather strip of claim 4 , wherein

the thick-walled portion is in a shape of a ridge extending continuously in an inward-outward direction of a passenger compartment of the automobile.
