摘要： A differential gear mechanism includes a housing, first and second sun gears each including an external gear portion, and first and second planetary gears. The first and second sun gears include axial end surfaces pressed against contact surfaces provided at the housing by the first and second sun gears by means of thrust forces generated at engagement surfaces between the external gear portions and the planetary gears. Each of the sun gears includes a first portion having the external gear portion, a second portion, and a thrust force generating mechanism for generating thrust forces at the first portion and the second portion. A direction of the thrust force generated at the first portion by the thrust force generating mechanism is specified to be equal to a direction of the thrust force generated at the first portion by means of the engagement between the external gear portion and the planetary gear.

摘要： In a vehicle differential unit according to an embodiment of the invention, a planetary carrier that is a rotatable member that rotatably supports planetary gears is formed of cylindrical members that are unable to rotate relative to each other on the rotational axis 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 of the pair of output shafts, and a relative movement limiting portion that limits a relative movement between the cylindrical members along the axial direction due to the thrust force when the vehicle is in the drive mode.

摘要： A driving force transmission apparatus includes: a first cam mechanism that converts rotational force from a housing into first cam thrust force used as clutch force of a main clutch when the first cam mechanism is actuated through clutch action of a pilot clutch; and a second cam mechanism that is actuated prior to conversion of the rotational force into the first cam thrust force by the first cam mechanism, and that generates second cam thrust force for reducing an interval between clutch plates of the main clutch. The second cam mechanism includes an input cam member that rotates upon receiving rotational force used as actuating force of the input cam member from a cam actuating driving source, and an output cam member that generates the second cam thrust force between the output cam member and the input cam member and outputs the second cam thrust force.
