Differential

A differential comprising:

• a first driving shaft;
• a second driving shaft;
• a first side gear whose rotation relative to the first driving shaft is restricted;
• a second side gear whose rotation relative to the second driving shaft is restricted, the second side gear being disposed coaxially with the first side gear;
• a case housing the first and second side gears, the case being configured to be rotated by a driving force from a driving source of a vehicle;
• a plurality of pinion gears configured to revolve around a rotation axis of the case in conjunction with the rotation of the case and transmit the driving force from the case to the first and second side gears while allowing differential rotations of the first and second side gears;
• a spacing member disposed into the case through an insertion hole of the case, the spacing member being partially disposed in an inter-shaft space between an axial end face of the first driving shaft and an axial end face of the second driving shaft so as to maintain a spacing of a predetermined distance or more between the first and second driving shafts;
• a meshing member disposed such that the meshing member is movable relative to the case in an axial direction and non-rotatable relative to the case, the axial direction being parallel to the rotation axis, the meshing member being configured to mesh with the second side gear so as to restrict rotation of the second side gear relative to the case;
• and
• a mover configured to move the meshing member in the axial direction between a first position where the meshing member is out of mesh with the second side gear and a second position where the meshing member is in mesh with the second side gear, wherein
• the meshing member is disposed between the first side gear and the second side gear.
