A differential case includes an outer shell wall portion configured to accommodate a pinion gear therein, and a first groove is formed in an inner surface of the outer shell wall portion on a back surface side of the pinion gear. In addition, a convex portion is formed on the inner surface of the outer shell wall portion on the back surface side of the pinion gear, and the first groove is formed in the convex portion. Further, a diameter of the convex portion is equal to or larger than a diameter of a back surface of the pinion gear.

Differential arrangement, e.g., for a drive axle of a motor vehicle. The differential arrangement comprises a drive wheel; a differential gear having an input part; a shift clutch operatively arranged between the drive wheel and the differential gear, wherein in the closed state of the shift clutch torque is transmitted from the drive wheel to the differential gear and in the open state of the shift clutch a torque transmission is interrupted. A first clutch part of the shift clutch is fixedly connected to the input part or to a differential housing of the differential gear, and a second clutch part of the shift clutch is fixedly connected to the respective other one of the input part and the differential housing.

In a support structure for a rotating member, in which a support body supporting a rotating member so as to be rotatable around a predetermined axis is provided with a spherical support face that is recessed toward a side opposite to the rotating member, and a back face of the rotating member is rotatably and slidably supported on the support face, the back face of the rotating member is formed as a convexly curved face that is curved so that portions on opposite sides of the axis each protrude toward the support face when viewed in a cross section containing an entirety of the axis. In order for the back face to be supported on the support face via an apex portion of the convexly curved face, a radius of curvature of at least the apex portion is set smaller than a radius of curvature of the support face.

In a differential device, paired side gears include shaft portions and intermediate wall portions formed in a flat plate shape intersecting an axis of the output shafts, the intermediate wall portions integrally connecting the shaft portions to toothing portions of the side gears separated outward from the shaft portions in a radial direction of an input member, respectively. Each of the intermediate wall portions is formed with a width in the radial direction which is longer than a maximum diameter of a pinion. A cover portion includes a boss portion and a side wall portion connected to the boss portion and having an outer side surface as a surface orthogonal to the axis of the output shafts. A back surface of at least one of the intermediate wall portion and the toothing portion is supported on an inner side surface of the side wall portion.

A side pinion is disclosed for use with a differential of a mobile machine. The side pinion may have a body with a flat bottom and a flat top located at an end opposite the flat bottom. The side pinion may also have a plurality of gear teeth formed adjacent the flat top, and an arcuate outer surface connecting the plurality of gear teeth to the flat bottom.
