The wiper structure for a resin window has a wiper for wiping the surface of a part of the resin window. The wiper has a wiper rubber (23) which is an elastic body, and a wiper holder for holding the wiper rubber (23). The wiper rubber has a holding base portion (23J), a lip portion (23A), a body portion (23D), and a neck portion (23E). The holding base portion (23J) is held by the wiper holder. The lip portion (23A) contacts the resin window. The body portion (23D) extends from the lip portion (23A) toward the holding base portion (23J), and has a thickness increasing from the lip portion (23A) toward the holding base portion (23J). The neck portion (23E) joins a body joint portion of the body portion (23D) and a holding joint portion of the holding base portion (23J) together, and has a thickness less than the thickness of the body joint portion and the thickness of the holding joint portion. In the lip portion (23A), the ratio between a lip thickness in the thickness direction and a lip length in a direction toward the surface of the resin window is greater than 0 and is less than or equal to 2.3.
树脂窗用刮水器构造具有刮拭树脂窗的局部的表面的刮水器。刮水器具有:弹性体的刮水器刮片(23)和保持刮水器刮片(23)的刮水器保持架。刮水器刮片具有保持基部(23J)、唇部(23A)、主体部(23D)和颈部(23E)。保持基部(23J)被刮水器保持架保持。唇部(23A)与树脂窗接触。主体部(23D)从唇部(23A)起向保持基部(23J)延伸并且随着从唇部(23A)向保持基部(23J)去而厚度变厚。颈部(23E)将主体部(23D)的主体连接部和保持基部(23J)的保持连接部连接起来并且厚度比主体连接部的厚度和保持连接部的厚度薄。唇部(23A)的在厚度方向上的唇厚度与朝向树脂窗的表面去的方向上的唇长度之比大于零且为2.3以下。
