PURPOSE:To securely prevent car body vibration or in-car noise caused by vibration at a wiper driving part by absorbing through a cover the vibration that occurs when the wiper driving part operates. CONSTITUTION:A cover 32 is formed by both an installing plate 33 to fasten a gear case 9 in a wiper driving part 5 and a car body bracket 14 to fasten a door-inner panel 13 that is welded to one side of the installing plate 33. The installing plate 33 is of sandwich structure in which resin 35 with viscoelsticity is inserted and press-fitted between two sheets of steel plates 34a and 34b. Thus, vibration produced in the one steel plate 34a is absorbed by elastic action by the resin 35, thereby preventing the vibration from transmitting to the other steel plate 34b. A door-trim cover 39 is places at the back surface of the wiper driving part 5 and fastened to the installing plate 33 by means of a clip 38. |
