The present disclosure provides a wet friction engaging device. The device includes a plate group engaged with two connecting members and including two groups of friction plates housed in a plate housing chamber and alternately arranged in an axial direction with surfaces facing each other. The plate group is switched between an engaged state in which the friction plates are in close contact with each other, and a disengaged state in which the friction plates are separable from each other. End plates at respective ends of the plate group are kept at a larger distance in the axial direction after a switch to the disengaged state than in the engaged state.
