In a power switching apparatus which moves cages respectively corresponding to left and right two driven members in an axial direction, end surfaces of the respective cages are brought into frictional contact with the driven members so as to rotate together therewith, and a wedge connection occurs in a circumferential connection surface of a drive member to each of circumferential connection surfaces in both of the driven members according to an interposition of rolling elements, at a time of switching a power transmitting state from the drive member to both of the driven members. A spacer which is coaxially arranged with the driven members is provided between both of the driven members, and both of the cages are coaxially supported by an outer periphery of the spacer.
