Abstract
A motor unit for operating a functional member of a vehicle includes a motor portion and a gearing portion. The gear portion includes a wheel gear intermeshed with a worm gear driven by a shaft. The shaft is supported by a plurality of mounts. At least one of the mounts and the shaft defines a complementary contacting surface having a bowed cross section. The bowed cross section minimizes any misalignment problems of the shaft and reduces deformation of the shaft when torque is blocked.

A motor unit for a vehicle, comprising:
- a motor having a shaft;
- a plurality of mounts to rotatably support said shaft, at least one of said mounts and said shaft defining a contact surface;
- said contact surface having a bowed cross section, said bowed cross section having a central portion formed on said at least one of said mount and said shaft which is spaced closer to the other than axially spaced side portion to form said bowed cross-section.
A motor unit for a vehicle, comprising:
- a motor;
- a shaft driven by said motor, said shaft having a first end and an opposed end;
- a first mount to rotatably support said first end of said shaft;
- a second mount to rotatably support an intermediate portion of said shaft;
- a third mount to rotatably support said opposed end of said shaft, said third mount and said shaft defining a contact surface;
- said contact surface having a bowed cross section, said bowed cross section having a central portion formed on said at least one of said mount and said shaft which is spaced closer to the other than axially spaced side portions to form said bowed cross-section.
