Abstract

A motor drive unit having an inboard brake in which a lateral weight distribution is balanced is provided. In the motor drive unit, output torque of a drive motor is distributed to a right driveshaft and a left driveshaft via a drive gear a drive gear fitted onto an output shaft thereof. A brake rotor is also fitted onto the output shaft to be rotated integrally therewith. A brake device stops rotation of the drive gear by engaging the brake rotor with a brake stator that is allowed to rotate relatively to the brake rotor but restricted to rotate in a rotational direction of the brake rotor. The brake device is disposed on an opposite side of the drive motor across the drive gear.
