A wiper apparatus for a motor vehicle comprising a sleeve secured to a vehicle body side and a pivot shaft which is supported rotatably in the sleeve. The proximal portion of the pivot shaft relative to the interior side of the vehicle is connected to a drive source. The tip portion of the pivot shaft holds a wiper arm on the exterior side of the vehicle. For the pivot shaft to depress toward the vehicle's interior side with respect to the sleeve, a load exceeding a predetermined value works axially on the pivot shaft from the vehicle's exterior side. A depression preventing member is interposed between the pivot shaft and the sleeve and is deformed when receiving the load that depresses the pivot shaft. A deformation space is secured between the pivot shaft and the sleeve enabling the depression preventing member to deform smoothly in response to the load.
