徴とするものである。Means for Solving the Problems The present invention provides a mount structure for a differential device as described above, in which the differential member is composed of a U-shaped cross-sectional member having an upper surface, a lower surface, and a vertical surface. A notch is formed in the vertical and lower surfaces of the central portion of the differential member to form a notch into which the boss of the differential device is fitted, and when the boss is fitted into the notch, the vertical surface of the differential member is cut out. A bracket having a substantially L-shaped cross section that is connected to the top surface and the bottom surface is bonded and fixed to the differential member so as to cover a portion of the bottom surface and the vertical surface of the notch, and the boss portion is connected to the top surface of the differential member and the bottom surface of the bracket. It is characterized by a structure in which it is fixed by tightening bolts in a large, recessed state.
