Differential device

A differential device, comprising:

• a casing rotatable about an axis;
• a differential gear set including
• a pair of side gears housed in the casing and rotatable about the axis,
• a pinion shaft penetrating perpendicular to the axis and being secured to the casing whereby the pinion shaft is rotatable along with the casing about the axis, and
• pinion gears rotatably supported by the pinion shaft and so meshed with the side gears as to enable differential motion between the side gears;
• friction clutches interposed between the side gears and an inner periphery of the casing to limit the differential motion;
• a pair of repulsive bodies respectively applying force in directions along the axis to the friction clutches;
• and
• a block in contact with and supporting, in the directions along the axis, both the repulsive bodies, wherein the block fits on the pinion shaft so as to impose reaction forces via the repulsive bodies from the friction clutches on the pinion shaft, wherein the repulsive bodies are respectively interposed between the block and the side gears to impose the reaction forces on the block,
• wherein the pair of repulsive bodies is in direct contact with the pair of side gears.
