  • Patent number: 11433746
    Abstract: A protrusion is formed on a first part of an inner-cabin side wall of an installation base member of a protector with a sensor. The first part is closer to a connecting wall than a second part opposite the first part. The protrusion is on a virtual line in cross section. The virtual line is where convex substances, keys for example, hanging on passengers' clothes conceivably pass through. The virtual line extends toward a connecting point from a rear part of an automobile body closer to an interior of the automobile body than a reference line. The reference line is parallel with a direction in which a flange protrudes and extends from the connecting point. The connecting point is a part of an inner-cabin side end of a hollow part closest to an interior of the automobile body. The inner-cabin side end is connected with the installation base member.
