Zusammenfassung:	A motor unit includes a shaft and an electrical discharging device. The shaft includes a helical gear. The electrical discharging device includes a contact member, a biasing member, and a case. The biasing member biases the contact member toward an end face of an end part of the shaft in a direction parallel to the axial direction of the shaft. The contact member has conductivity. The contact member is brought into contact with the end face by the biasing of the biasing member. The maximum stroke amount of the contact member in the axial direction is larger than the movement width of the shaft in the axial direction during rotation.
