A vehicle including a drive unit that has an engine (11, 12, 13) and a motor and is a drive source for travel of the vehicle, wherein the engine (11, 12, 13) has an engine output shaft configured to output drive power and an engine housing configured to constitute an outer coat, the motor has a rotor, a stator, a motor output shaft that is joined to the rotor and configured to output drive power, and a motor housing configured to constitute an outer coat, the engine housing and the motor housing are integrally formed or are joined to each other, the engine output shaft and the motor output shaft are integrally formed or are joined to each other in a manner to rotate coaxially and synchronously, the rotor of the motor has a main body section configured to generate a rotational magnetic field with the stator, and a weight section configured to function as a balance weight of the engine (11, 12, 13), and when a direction that is orthogonal to an extending direction of the motor output shaft is set as a radial direction, the weight section has an intermediate section that extends obliquely from the motor output shaft side and an opposite side of the engine housing toward an outer side in the radial direction and the engine housing side, and an outer edge section that continues from the intermediate section and extends outward in the radial direction in the case where the weight section of the rotor is seen in a cross section including an axis of the motor output shaft, characterized in that a distance Ra from the axis of the motor output shaft to an outer circumferential surface of the outer edge section satisfies the following relationship with a distance Rd from the axis to an inner circumferential surface of the stator to a distance Rc from the axis to an outer circumferential surface of the stator: Rc > Ra > Rd. the engine (11, 12, 13) has an engine output shaft configured to output drive power and an engine housing configured to constitute an outer coat, the motor has a rotor, a stator, a motor output shaft that is joined to the rotor and configured to output drive power, and a motor housing configured to constitute an outer coat, the engine housing and the motor housing are integrally formed or are joined to each other, the engine output shaft and the motor output shaft are integrally formed or are joined to each other in a manner to rotate coaxially and synchronously, the rotor of the motor has a main body section configured to generate a rotational magnetic field with the stator, and a weight section configured to function as a balance weight of the engine (11, 12, 13), and when a direction that is orthogonal to an extending direction of the motor output shaft is set as a radial direction, the weight section has an intermediate section that extends obliquely from the motor output shaft side and an opposite side of the engine housing toward an outer side in the radial direction and the engine housing side, and an outer edge section that continues from the intermediate section and extends outward in the radial direction in the case where the weight section of the rotor is seen in a cross section including an axis of the motor output shaft, characterized in that a distance Ra from the axis of the motor output shaft to an outer circumferential surface of the outer edge section satisfies the following relationship with a distance Rd from the axis to an inner circumferential surface of the stator to a distance Rc from the axis to an outer circumferential surface of the stator: Rc > Ra > Rd.
