[0009] In the above-mentioned vehicle door pillar plate structure, the width of the third connecting surface is the same as the width of the first connecting surface so that one side of the sealing strip is flush with one side of the pillar cover plate.

[0010] In the above-mentioned vehicle door pillar plate structure, the width of the fourth connecting surface is smaller than or equal to the width of the second connecting surface so that one side of the sealing strip is concave relative to one side of the pillar cover plate.

[0011] In the above-mentioned vehicle door pillar plate structure, the sealing strip is a thermoplastic vulcanized rubber part.

[0012] In the above-mentioned door pillar plate structure, the pillar cover plate includes a reinforcement portion and an appearance portion, the appearance portion is connected to the reinforcement portion, and the first connection portion is located at the reinforcement portion.

[0020] 4. The width of the third connection surface is the same as that of the first connection surface so that one side of the sealing strip is flush with one side of the column cover. From the appearance, the connection between the sealing strip and the column cover is relatively flat and smooth.

[0021] 5. The width of the fourth connecting surface is less than or equal to the width of the second connecting surface so that one side of the sealing strip is concave relative to one side of the pillar cover plate, thereby preventing the sealing strip from contacting the side of the pillar cover plate close to the body side, thereby causing the mold structure to fail to form.
