Abstract:
A friction engaging device comprising:a first friction engaged member;a second friction engaged member so held as to be relatively rotatable with respect to said first friction engaged member;first friction engaging means used for providing a friction engagement between said first friction engaged member and said second friction engaged member;a variable length joint provided between said first friction engaging means and said first friction engaged member, and including a first operation element facing to said first friction engaging means and movable in an axial direction and a second operation element so held as to be only relatively rotatable with respect to said first friction engaged member, any one of said first and second operation elements rotating with said second friction engaged member, said first and second operation elements moving away from each other in the axial direction corresponding to the relative rotations in order to make said first friction engaging means perform the engaging operation on one hand, and becoming proximal to each other in the axial direction on the other hand, thus making the relative rotations; andsecond friction engaging means used for providing a friction engagement between said first operation element or said second operation element which does not rotate with said second friction engaged member, and said first friction engaged member;said second friction engaging means including a tube type clutch.
