Abstract
A power transmission unit for a vehicle comprises: a motor arranged on an output side of an engine coaxially therewith in a housing adjacent to an outer face of the engine; an end cover arranged in the housing to cover an end portion of the motor to protect from the engine; a rotary shaft extending coaxially with the motor to be connected to an output shaft of the engine while penetrating through the end cover; and an engagement device disposed on an outer circumferential side of the rotary shaft between the motor and the engine to selectively restrict a rotation of the rotary shaft. A sub-cover to which the rotary shaft penetrates is attached to an end face of the end cover and a chamber is hermetically enclosed by the sub-cover, the end cover, and the rotary shaft. The engagement device is held in the housing.
