Power switching apparatus

In a power switching apparatus (10) which moves cages (41,42) respectively corresponding to left and right two driven members (21,22) in an axial direction, end surfaces of the respective cages (41,42) are brought into frictional contact with the driven members (21,22) so as to rotate together therewith, and a wedge connection occurs in a circumferential connection surface (30) of a drive member to each of circumferential connection surfaces in both of the driven members according to an interposition of rolling elements (43,44), at a time of switching a power transmitting state from the drive mem
