PROBLEM TO BE SOLVED: To provide a motor device the weight of which can be reduced furthermore, by establishing a structure capable of reducing radio wave noise, while resinifying a gear housing.SOLUTION: A gear housing 31 is formed of a resin material, an output shaft 38 and a bracket member 40 are formed of a conductive material, and a conductive member 45 for connecting the output shaft 38 and bracket member 40 electrically is provided therebetween. Consequently, even if radio wave noise discharged to the outside of a rear wiper motor 10 is absorbed by the output shaft 38, the radio wave noise is propagated from the output shaft 38 via the conductive member 45 to the bracket member 40, thence released to an attachment object, e.g., the car body. Sufficient earth performance can thereby be obtained, and enhancement of radio wave noise in the rear wiper motor 10 can be suppressed, while reducing the weight thereof. |
