摘要： In a vehicle differential unit according to an embodiment of the invention, a planetary carrier (2A) that is a rotatable member that rotatably supports planetary gears (2B) is formed of cylindrical members (20A, 21A) that are unable to rotate relative to each other on the rotational axis (O) of a pair of output shafts. The vehicle differential unit has a thrust force generation portion that receives a driving force from a drive source of a vehicle and generates a thrust force along the direction of the rotational axis (O) of the pair of output shafts, and a relative movement limiting portion that limits a relative movement between the cylindrical members (20A, 21A) along the axial direction due to the thrust force when the vehicle is in the drive mode.

摘要： A power distribution apparatus of high reliability and long life and that can be reduced in size. A differential gear identified as a power transmission mechanism includes a drive shaft, a diff case provided with an opening that opens towards the drive shaft, constant velocity universal joints connected to the drive shaft, and side gears connected to drive shafts via the constant velocity universal joints. Outer races of the constant velocity universal joints are formed at the end of drive shafts. Inner races of the constant velocity universal joints are formed at side gears. The outer races are arranged so as to block an opening.

摘要： PROBLEM TO BE SOLVED: To provide a differential gear for a vehicle having a large differential limit force. SOLUTION: This differential gear is provided with a housing 2 rotated and driven with a rotary axis line L as a center, a pair of sun gears 3, 4 rotatably arranged in the housing 2 with the rotary axis line as a center, and at least a pair of mutually-engaged planetary gears 5, 6 arranged in the housing 2 to be rotated on their axes while being engaged with the sun gears 3, 4, respectively. The sun gears 3, 4 and the planetary gears 5, 6 are provided with spiral gears. Between the sun gears 3, 4, a main clutch 8 composed of a friction clutch is provided. When an electric current passes through an electromagnet 9, the first and second clutch discs of the main clutch 8 are press-contacted with each other, and friction resistance limiting the relative rotation of the sun gears 3, 4 is generated between them.
